Daim ntawv thov
Nws yog siv los ua ke chloroformates, isocyanates, polycarbonates thiab acyl chloride.
Triphosgene, tseem hu ua di (trichloromethyl) carbonate, yog cov organic compound nrog cov tshuaj formula C3Cl6O3, ib tug dawb crystalline hmoov uas decomposes me ntsis ntawm lub boiling point los tsim trichloromethyl chloroformate thiab phosgene, feem ntau yog siv nyob rau hauv lub synthesis ntawm chloroformate, isocyanate, polycarbonate. thiab chloroformyl chloride, thiab lwm yam. Nws yog dav siv los ua ib qho nruab nrab hauv plastics, pharmaceuticals, herbicides thiab tshuaj tua kab.
Nws yog siv nyob rau hauv lub synthesis ntawm chloroformate, isocyanate, polycarbonate thiab chloride, thiab lwm yam. Khoom phosgene, tseem hu ua triphosgene, yog synthesized los ntawm dimethyl carbonate - ib tug ntsuab chemical khoom, uas yog heev reactive thiab muaj peev xwm hloov phosgene nyob rau hauv ntau yam tshuaj tiv thaiv, thiab Cov tshuaj tiv thaiv tseem ceeb uas nws tuaj yeem koom nrog yog: chloromethylation, carbonic acid esterification, urelation, isocyanate esterification, chlorination, isonitriles, lub nplhaib tsim cov tshuaj tiv thaiv, alpha-chlorination ntawm aldehydes Formylation, oxidation ntawm cawv, thiab lwm yam hauv cov organic synthesis, khoom phosgene. tuaj yeem hloov oxalyl chloride ua tus activator ntawm dimethyl sulfoxide hauv cov tshuaj tiv thaiv oxidation ntawm cawv thiab siv tau yooj yim thiab nyab xeeb hauv kev npaj cov tshuaj hydroxyl;khoom phosgene kuj tuaj yeem hloov ntau hom cawv rau hauv cov tshuaj chlorinated sib xyaw.Hauv kev lag luam kws tshuaj, khoom phosgene tuaj yeem hloov phosgene hauv kev sib txuas ntawm ntau tus kws tshuaj.
