Chemical Properties:

Propylene oxide, tseem hu ua propylene oxide, methyl ethylene oxide, 1,2-epoxypropane, yog cov organic compound nrog cov tshuaj formula C3H6O. Nws yog ib qho tseem ceeb raw khoom rau cov organic tebchaw thiab yog qhov thib peb tseem ceeb tshaj plaws propylene derivative tom qab polypropylene thiab acrylonitrile. Epoxypropane yog cov kua tsis muaj xim etheric, tsis tshua muaj kub kub taw tes, flammable, chiral, thiab cov khoom lag luam feem ntau yog sib xyaw ntawm cov enantiomers. Ib nrab miscible nrog dej, miscible nrog ethanol thiab ether. Tsim binary azeotropic sib tov nrog pentane, pentene, cyclopentane, cyclopentene thiab dichloromethane. Toxic, irritating rau mucous daim nyias nyias thiab daim tawv nqaij, tuaj yeem ua rau lub ntsej muag thiab conjunctiva, ua rau mob ua pa, tawv nqaij kub hnyiab thiab o, thiab txawm tias cov ntaub so ntswg necrosis.

Daim ntawv thov:

Nws tuaj yeem siv los ua tus neeg ua kom lub cev qhuav dej rau kev npaj cov slides hauv electron microscopy. Kev ua haujlwm dermatitis kuj tau tshaj tawm thaum siv cov tshuaj tua kab mob ntawm daim tawv nqaij.

Tshuaj intermediate hauv kev npaj ntawm polyethers los ua polyurethanes; nyob rau hauv kev npaj ntawm urethane polyols thiab propylene thiab dipropylene glycols; nyob rau hauv kev npaj ntawm lubricants, surfactants, roj demulsifiers. Raws li hnyav; fumigant; av sterilant.

propylene oxide yog siv los ua fumigant rau zaub mov; raws li ib tug stabilizer rau fuels, tshav kub-ing roj, thiab chlorinated hydrocarbons; asa fuel-air explosive in munitions; thiab toenhance qhov lwj tsis kam ntawm ntoo thiab particleboard (Mallari li al. 1989). Cov kev tshawb fawb tsis ntev los no qhia tau hais tias qhov fumigant muaj peev xwm ntawm propylene oxide txhim kho ntawm qhov tsis tshua muaj siab ntawm 100 mm Hg uas tuaj yeem ua rau nws hloov pauv rau methyl bromide rau kev tua kab mob sai ntawm cov khoom lag luam.
