paraldehyde usage and synthesis |
chemical properties | colourless to yellowish clear liquid |
usage | paraldehyde is used as solvent for fats, oils, waxes, rubber and resins; as substitute for acetaldehyde; as intermediate for organic chemicals, dyestuffs, accelerators for vulcanizations, rubber oxidants, etc. product data sheet |
usage | reactant involved in:• ;modified sanford reaction1• ;synthesis of n-arylbenzoquinaldinium derivatives with antimicrobial activity2• ;hydroformylation of alkenylamines3• ;studies of molecules with inhibitory activity against hiv-1 integrase4• ;irregular wittig reactions for the formation of α-hydroxyketones5 |
general description | 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. |
air & water reactions | highly flammable. slightly soluble in water. decomposed by light and air, on prolonged storage, to acetaldehyde and acetic acid. |
reactivity profile | 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. |
health hazard | 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). |
