Ukusetyenziswa kweTriphosgene
Njengemveliso ethatha indawo ye-phosgene enetyhefu kakhulu kunye ne-diphosgene kwi-synthesis, imveliso inobuthi obuphantsi, usetyenziso olukhuselekileyo kunye nolufanelekileyo, iimeko zokusabela kancinci, ukukhetha okulungileyo kunye nesivuno esiphezulu.
Ukwenza i-chloroformate, isocyanate, i-polycarbonate kunye ne-asidi chloride, ii-isocyanates ezahlukeneyo zinokulungiswa nge-carbonylation ye-phosgene ene-amine yokuqala, kodwa ukuphendula okusemacaleni kaninzi kwenzeka ngenxa yokuba iphosgene kunzima ukuyilinganisa ngokuchanekileyo.I-Triphosgene iqinile, inokulinganiswa ngokuchanekileyo, kwaye i-triphosgene isetyenziselwa ukutshintsha i-phosgene, ephucula kakhulu ukhuseleko lwayo, ngoko inokubuyisela ngokukhuselekileyo i-phosgene.Ukusabela kwe-Triphosgene kunye ne-amine compounds yintsimi esetyenziswa ngokubanzi.Ukusabela kunokukhetha okunamandla.Amanye amaqela asebenzayo ayifuni ukukhuselwa, kwaye anokuvelisa ngokuthe ngqo i-isocyanates, urea kunye nezinye iikhompawundi.Ii-isocyanates ezahlukeneyo zinokudityaniswa yi-carbonylation reaction ye-Triphosgene kunye nee-amine ezahlukeneyo eziphambili.Imveliso ekujoliswe kuyo inokufumaneka ngokulawula ngokuchanekileyo umlinganiselo we-Triphosgene kunye ne-amine ngaphandle kweemveliso.Ngokomzekelo, i-2,4-dimethyldisocyanate (TDI) inokuqulunqwa ngokusabela kwe-Triphosgene kunye nencwadi yeekhemikhali 2,4-Diaminotoluene;I-Triphosgene isabela nge-4,4 '- diaminodiphenylmethane ukuvelisa i-4,4′ - i-diphenylmethane diisocyanate (MDI);I-sodium hexamethylene diisocyanate (HDI) inokuveliswa yi-triphosgene kunye ne-hexamethylene diamine.Kwi-carbonylation reaction ye-BTC, ukusabela kwe-cyclization condensation nako kunokwenziwa.I-Triphosgene isetyenziswa ngokubanzi kolu hlobo lokuphendula, olungasetyenziselwa ukulungisa i-n-carbonyl anhydride, i-heterocyclic compounds ebalulekileyo eyahlukeneyo kunye ne-cyclic carbonate compounds.Eyangaphambili ingasetyenziselwa ukulungiselela i-amino acids esebenzayo kunye neekhompawundi ze-polypeptide, kwaye le yokugqibela ingasetyenziselwa ukulungisa amayeza ahlukeneyo kunye ne-pesticide intermediates.
