Application
Inoshandiswa kugadzira chloroformates, isocyanates, polycarbonates uye acyl chloride.
Triphosgene, inozivikanwawo se di(trichloromethyl) carbonate, inhengo yeorganic ine kemikari formula C3Cl6O3, chena crystalline poda inoora zvishoma painofashaira kuti ibudise trichloromethyl chloroformate uye phosgene, inonyanya kushandiswa mukugadzirwa kwechloroformate, isocyanate, polycarbonate. uye chloroformyl chloride, etc. Inoshandiswa zvakanyanya sepakati mumapurasitiki, mishonga, mishonga yesora nemishonga yezvipembenene.
Inoshandiswa mukugadzira chloroformate, isocyanate, polycarbonate uye chloride, etc. Solid phosgene, inozivikanwawo se triphosgene, inogadzirwa kubva ku dimethyl carbonate - makemikari egirini, ayo anoshanda zvakanyanya uye anogona kutsiva phosgene mune akasiyana makemikari maitiro, uye. mhando huru dzemabatiro aanogona kuita ndeaya: chloromethylation, carbonic acid esterification, urelation, isocyanate esterification, chlorination, isonitriles, ring formation reactions, alpha-chlorination yealdehydes Formylation, oxidation of alcohols, etc. In organic synthesis, solid phosgene. inogona kutsiva oxalyl chloride se activator ye dimethyl sulfoxide mune oxidation reaction yezvinwiwa uye kushandiswa zviri nyore uye zvakachengeteka mukugadzira hydroxyl makomisheni;yakasimba phosgene inogonawo kushandura marudzi akasiyana ezvinwiwa muzvikamu zvinoenderana nekloriniti.Muindasitiri yemishonga, phosgene yakasimba inogona kutsiva phosgene mukubatanidzwa kwenhamba huru yemishonga.
