Isicelo
Isetshenziselwa ukuhlanganiswa kwe-chloroformates, isocyanates, polycarbonates ne-acyl chloride.
I-Triphosgene, eyaziwa nangokuthi i-di(trichloromethyl) carbonate, iyinhlanganisela ye-organic enefomula yamakhemikhali i-C3Cl6O3, i-crystalline powder emhlophe ebola kancane endaweni yokubilisa ukuze ikhiqize i-trichloromethyl chloroformate ne-phosgene, esetshenziswa kakhulu ekuhlanganiseni kwe-chloroformate, isocyanate, polycarbonate. kanye ne-chloroformyl chloride, njll. Isetshenziswa kabanzi njengendawo ephakathi kumapulasitiki, emithini yemithi, emithini yokubulala ukhula nezibulala-zinambuzane.
Isetshenziswa ekuhlanganiseni kwe-chloroformate, isocyanate, polycarbonate kanye ne-chloride, njll. I-phosgene eqinile, eyaziwa nangokuthi i-triphosgene, ihlanganiswa ne-dimethyl carbonate - into yamakhemikhali eluhlaza, esebenza kakhulu futhi engathatha indawo ye-phosgene ekuphenduleni kwamakhemikhali okuhlukahlukene, futhi izinhlobo eziyinhloko zokusabela okungahileleka kuzo yilezi: i-chloromethylation, i-carbonic acid esterification, i-urelation, i-isocyanate esterification, i-chlorination, i-isonitriles, ukusabela kokwakheka kwendandatho, i-alpha-chlorination ye-aldehydes Formylation, i-oxidation ye-alcohols, njll. Ku-organic synthesis, i-phosgene eqinile ingangena esikhundleni se-oxalyl chloride njenge-activator ye-dimethyl sulfoxide ekuphenduleni kwe-oxidation ye-alcohol futhi isetshenziswe kalula nangokuphepha ekulungiseleleni izinhlanganisela ze-hydroxyl;i-phosgene eqinile nayo ingashintsha izinhlobo ezahlukene zotshwala zibe izinhlanganisela ezihambisana ne-chlorinated.Embonini yezemithi, i-phosgene eqinile ingangena esikhundleni se-phosgene ekuhlanganisweni kwenani elikhulu lemithi.
