PENTAERYTHRITOL

Pentaerythritol is used in the manufacture of the high explosive pentaerythritol tetranitrate, or PETN. Another common use is in synthetic alkyd resins used for surface coatings such as paints and varnishes, and in the production of pentaerythritol triacrylate (ACGIH, 1991; Budavari, 1989) Hathaway, 1991).
Other uses for pentaerythritol include the production of rosin and tall oil esters, pharmaceuticals, insecticides, synthetic lubricants, paint-swelling agents, plasticizers, and stabilizers (ACGIH, 1991; Lewis, 1993; Lewis, 1996).

FORMS

The technical grade of pentaerythritol consists of 88% monopentaerythritol and 12% dipentaerythritol, with a very small amount of the trimer (Lewis, 1993; ACGIH, 1991).

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

Pentaerythritol is mildly toxic. Exposure in experimental animals has caused eye irritation, ataxia, tremors, loss of righting reflex, and diarrhea.

POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 134 (ERG, 2004)

SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 134 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
For minor skin contact, avoid spreading material on unaffected skin.
Keep victim warm and quiet.
Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

FIRST AID

FIRST AID

EYE EXPOSURE - Immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical.
DERMAL EXPOSURE - Wash the contaminated skin with water.
INHALATION EXPOSURE - Move the exposed person to fresh air at once. Other measures are usually unnecessary.
ORAL EXPOSURE - If this chemical has been swallowed, get medical attention immediately.
TARGET ORGANS - Eyes and respiratory tract (National Institute for Occupational Safety and Health, 2007).

GENERAL -

Move victims of inhalation exposure from the toxic environment and administer 100% humidified supplemental oxygen with assisted ventilation as required. Exposed skin and eyes should be copiously flushed with water. Following ingestion, measures to decrease absorption may be useful if the patient is seen soon after the exposure.

INHALATION EXPOSURE -

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.

DERMAL EXPOSURE -

DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999).

EYE EXPOSURE -

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

ORAL EXPOSURE -

GASTRIC LAVAGE: Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in the head down left lateral decubitus position or by endotracheal intubation. Control any seizures first.

CONTRAINDICATIONS: Loss of airway protective reflexes or decreased level of consciousness in unintubated patients; following ingestion of corrosives; hydrocarbons (high aspiration potential); patients at risk of hemorrhage or gastrointestinal perforation; and trivial or non-toxic ingestion.

ACTIVATED CHARCOAL: Administer charcoal as a slurry (240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old.
Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury.

ANIMAL DATA

Pentaerythritol has been shown to be of very low toxicity (Hathaway, 1991).
Exposure to 8000 mg/m(3) of technical pentaerythritol for 6 hours per day for 90 days caused no adverse effects in rats, dogs, and guinea pigs (ACGIH, 1991).
Oral doses of up to 16 g/kg were not lethal in rats (ACGIH, 1991).
Laxative effects were observed in guinea pigs exposed to 20 g/kg and albino rats exposed to 40 g/kg. No serious effects were noticed (HSDB , 1996).
Only slight temporary eye irritation was observed in rabbits exposed to a 50 percent aqueous suspension placed into the conjunctival sac (ACGIH, 1991).
No dermal absorption or irritation has been observed in rabbit studies (ACGIH, 1991) Hathaway, 1991).

CONTAINMENT/WASTE TREATMENT OPTIONS

SUMMARY

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 134 (ERG, 2004)
- Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire.
- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
- Stop leak if you can do it without risk.
- Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
- Prevent entry into waterways, sewers, basements or confined areas.
- Use clean non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 134 (ERG, 2004)
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
- Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.

WASTE TREATMENT OPTIONS

BIOREMEDIATION

Biological treatment may be an effective means for treating pentaerythritol-contaminated wastewater streams (HSDB , 1996).
Waste management activities associated with material disposition are unique to individual situations. Proper waste characterization and decisions regarding waste management should be coordinated with the appropriate local, state, or federal authorities to ensure compliance with all applicable rules and regulations.

-ENVIRONMENTAL HAZARD MANAGEMENT

POLLUTION HAZARD

Pentaerythritol may be released to the environment through its production, use, and disposal (HSDB , 1996).

ENVIRONMENTAL FATE AND KINETICS

Pentaerythritol is most likely to be present in the particulate phase in the atmosphere. It may be removed by dry deposition or partially removed by wet deposition. Vapor phase pentaerythritol is not likely to occur because of its low volatility; however if reaction with photochemically-produced hydroxyl radicals does occur, it is estimated to have a half-life of 1 day (HSDB , 1996).

WATER

SURFACE WATER
- Pentaerythritol is likely to be present in the aquatic phase in water. Biodegradation in water may be an important removal process. Hydrolysis and photolysis are not expected to occur. Based on the estimated Koc of 9, adsorption to suspended solids and sediments should not be an important fate process (HSDB , 1996).

SOIL

TERRESTRIAL
- Biodegradation is expected to be an important removal process for pentaerythritol in soil. It is likely to be highly mobile in soil, based on its estimated Koc of 9. However, mobility may be retarded because of pentaerythritol's tendency to form complexes with many metals under favorable conditions. Volatilization from soil should not be an important fate process (HSDB , 1996).

ABIOTIC DEGRADATION

Pentaerythritol has no functional groups which are amenable to either hydrolysis or photolysis (HSDB , 1996).

BIODEGRADATION

Anaerobic biodegradation of pentaerythritol is likely to occur. However, differences in test methods and conditions have led to differing conclusions in studies done to determine the chemical's susceptibility to aerobic biodegradation (HSDB , 1996).

BIOACCUMULATION

FISH

Bioconcentration of pentaerythritol is not likely in aquatic organisms (HSDB , 1996).

BIOCONCENTRATION FACTOR

The bioconcentration of pentaerythritol is estimated at 1, indicating that bioconcentration is not expected in aquatic organisms (HSDB , 1996).

ENVIRONMENTAL TOXICITY

The effect of low concentrations of pentaerythritol on aquatic life is unknown ((CHRIS, 1996)).

SOLUBILITY

IN WATER

Pentaerythritol is very soluble in hot water (772 g/100 g at 97 degrees C). It is moderately soluble in cold water (7.23 g/100 g at 25 degrees C) (ACGIH, 1991).
Its solubility in water at 59 degrees F is 6 percent by weight (NIOSH , 1996).
On gram pentaerythritol dissolves in 18 mL water at 15 degrees C (Budavari, 1989).
The estimated water solubility is 72,300 mg/L (HSDB , 1996).

IN ORGANIC SOLVENTS

It is soluble in formamide, ethylene glycol, ethanol, and glycerol (ACGIH, 1991; Budavari, 1989).
It is insoluble in carbon tetrachloride, ether, benzene, acetone, petroleum ether, and paraffin (ACGIH, 1991; Lewis, 1993; Budavari, 1989).
