Aroma threshold values

Recognition at 0.02 to 0.025 mg/m3 (air).

一般的な説明

Paraldehyde, 2,4,6-trimethyl-strioxane,paracetaldehyde, is recognizable as the cyclictrimer of acetaldehyde. It is a liquid with a strong characteristicodor detectable in the expired air and an unpleasanttaste. These properties limit its use almost exclusively toan institutional setting (e.g., in the treatment of deliriumtremens). In the past, when containers were opened and airadmitted and then reclosed and allowed to stand, fatalitiesoccurred because of oxidation of paraldehyde to glacialacetic acid.

一般的な説明

A clear colorless liquid with a pleasant odor. Flash point 96°F. Melting point 54°F. Less dense than water. Vapors are heavier than air.

空気と水の反応

Highly flammable. Slightly soluble in water. Decomposed by light and air, on prolonged storage, to acetaldehyde and acetic acid.

反応プロフィール

Paraldehyde is an aldehyde. Paraldehyde is decomposed by light and air, on prolonged storage, to acetaldehyde and acetic acid. Incompatible with alkalis, hydrocyanic acid iodides and oxidizers.

健康ハザード

INHALATION AND INGESTION: Irritation, headache, bronchitis, pulmonary edema. Irritating to digestive tract. Hypnotic and analgesic properties. Incoordination and drowsiness, followed by sleep. Larger doses-coma-weak pulse and shallow respiration, cyanosis-death from respiratory paralysis. EYES: irritation-can cause serious injury. SKIN: Dermatitis (skin inflammation).

安全性プロファイル

A human poison by rectal route. Moderately toxic to humans by intramuscular route. Moderately toxic experimentally by inhalation, ingestion, intraperitoneal, and subcutaneous routes. Human systemic effects by rectal route: necrotic changes. A skin and severe eye irritant. Low doses produce hypnotic and analgesic effects. Larger doses depress the nervous system with loss of reflexes, coma, and respiratory depression leadmg to respiratory paralysis and death. Chronic effects include weight loss, muscular weakness, and mental fatigue. However, poisoning is rare. A hypnotic agent. Dangerous fire hazard when exposed to heat, flame, or oxidzers. Slight explosion hazard when exposed to heat or flame. Dangerous; keep away from heat and open flame. To fight fire, use alcohol foam, CO2, dry chemical. Potentially violent reaction with nitric acid. Incompatible with alkahes, hydrocyanic acid, iodides, oxidzers. When heated to decomposition it emits acrid smoke and irritating fumes.

職業ばく露

Paraldehyde is used primarily in medicine. It is used as a hypnotic agent, in delirium tremens; and in treatment of psychiatric states characterized by excitement when drugs must be given over a long period of time. It also is administered for intractable pain which does not respond to opiates and for basal and obstetrical anesthesia. It is effective against experimentally induced convulsions and has been used in emergency therapy of tetanus, eclampsia, status epilepticus; and poisoning by convulsant drugs. Since it is used primarily in medicine, the chance of accidental human exposure or environmental contamination is low. However, paraldehyde decomposes to acetaldehyde and acetic acid; these compounds have been found to be toxic. In this case, occupational exposure or environmental contamination is possible. Since paraldehyde is prepared from acetaldehyde by polymerization in the presence of an acid catalyst, there exists a potential for adverse effects, although none have been reported in the available literature. It is also used in the manufacture of organic compounds.

輸送方法

UN1264 Paraldehyde, Hazard Class: 3; Labels: 3-Flammable liquid.

純化方法

Wash paraldehyde with water and fractionally distil it. Alternatively, it is purified by drying with anhydrous Na2SO4, then cooled to 5o, and the frozen material is separated by decantation. The solid is distilled (b 121-124o/atm), the distillate is collected, stored over anhydrous Na2SO4 for several days and re-distilled at atmospheric pressure before use [Le Fevre et al. J Chem Soc 290 1950]. The 2r,4c,6t-trimethyl-1,3,5-trioxane has m 14.5o, b 125o/760mm. [Beilstein 19 II 394, 19 III/IV 4715. 19/9 V 112.]

不和合性

Vapor or liquid may form explosive mixture with air. Incompatible with strong oxidants, strong acids; alkalis, ammonia, amines, iodides, hydrocyanic acid. Violent reaction with liquid oxygen. Contact with acids form acetaldehyde. Attacks rubber and plastics.

廃棄物の処理

Incineration in added solvent. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
