Product Description
Propylene oxide is also known as ethylene chloride, 1, 2-propylene oxide, propylene oxide, methyl ethylene oxide, referred to as P.O. It is a colorless, flammable and volatile liquid with ether-like odor. Molecular weight 58.08. The relative density is 0.823(25ºC). Melting point -112.13ºC. Boiling point 34.23ºC. Refractive index 1.3664. Flash point -35ºC(closed). Ignition point 420ºC. Vapor pressure (Pa) : 1.04 x 104 (20 ºC), 104 (0 ºC) 2.80 x, 6.53 x 104 (20 ºC), 7.59 x 104 (25 ºC). It is soluble in water (40.5 at 20 ° C, 60 at 30 ° C) and miscible with most general reagents. It is composed of binary azeotrope with water (1%), and the azeotrope point is 39.9ºC. It can also form binary azeotrope with dichloromethane, ethyl ether, cyclohexane, cyclopentane, pentene, etc. Vapor and air can form an explosive mixture with an explosion limit of 1.9% to 24%(volume fraction). It is optically active, with D-body specific rotation +12.72°(18 ° C) and lChemicalbook -8.26°(18 ° C). The epoxy group with high chemical activity exists in the molecule, which can carry out many chemical reactions. The chemical activity is slightly lower than that of ethylene oxide, which reacts with substances containing active hydrogen (such as water, alcohols, acids, amines) to produce diols, alcohol ethers, alcoholamines, etc. The hydrolysis reaction produces propylene glycol. Etherification reaction to produce alcohol ether. Under the action of catalyst, polyether polyols can be formed. Reacting with glycerol, polyether ternary alcohol is formed. Reacts with carboxylic acid to form ester. It reacts with ammonia to form an alkanol amine. It reacts with hydrogen halide to form halogenated alcohols. It reacts with hydrogen sulfide to form mercaptan. It reacts with phenthiophenol to form hydroxypropyl phenthioether. Under the action of trimethylamine catalyst, it reacts with carbon disulfide to produce allyl trithiocarbonate. Under the action of catalyst, it can be isomerized to produce propionaldehyde. Propylene oxide is toxic and irritating to the skin and eyes, even in a 1% dilute solution. Vapor stimulates respiratory organs and eyes, and has inhibitory effect on central nervous system after inhalation. Rat transoral LD50930mg/kg. The maximum allowable concentration in the workplace is 20×10-6.
