Triphosgene Kushandiswa
Sechinotsiva chigadzirwa cheiyo yakanyanya muchetura phosgene uye diphosgene mune synthesis, chigadzirwa chine yakaderera chepfu, yakachengeteka uye iri nyore kushandisa, zvinyoro maitiro mamiriro, kusarudza kwakanaka uye goho repamusoro.
Nekuumbwa kwe chloroformate, isocyanate, polycarbonate uye acid chloride,Isocyanates dzakasiyana-siyana dzinogona kugadzirwa necarbonylation yephosgene ine primary amine, asi mhinduro yemudivi inowanzoitika nekuti phosgene inonetsa kuyera nemazvo.Triphosgene yakasimba, inogona kuyerwa nemazvo, uye triphosgene inoshandiswa kutsiva phosgene, iyo inovandudza zvakanyanya kuchengetedzwa kwayo, saka inogona kutsiva yakachengeteka phosgene.Kuita kweTriphosgene ine amine makomboni inzvimbo inoshandiswa zvakanyanya.The reaction has strong selectivity.Mamwe mapoka anoshanda haadi kuchengetedzwa, uye anogona kuburitsa zvakananga isocyanates, urea uye mamwe makomisheni.Akasiyana-siyana isocyanates anogona kugadzirwa necarbonylation reaction yeTriphosgene uye akasiyana ekutanga amines.Chigadzirwa chinonangwa chinogona kuwanikwa nekunyatso kudzora reshiyo yeTriphosgene uye amine pasina ne-zvigadzirwa.Semuenzaniso, 2,4-dimethyldisocyanate (TDI) inogona kugadzirwa nekuita kweTriphosgene nebhuku remakemikari 2,4-Diaminotoluene;Triphosgene inopindirana ne 4,4 '- diaminodiphenylmethane kugadzira 4,4′ - diphenylmethane diisocyanate (MDI);Sodium hexamethylene diisocyanate (HDI) inogona kugadzirwa netriphosgene uye hexamethylene diamine.Mune iyo carbonylation reaction yeBTC, cyclization condensation reaction inogona zvakare kuitwa.Triphosgene inoshandiswa zvakanyanya mumhando iyi yekuita, iyo inogona kushandiswa kugadzira n-carbonyl anhydride, akasiyana akakosha heterocyclic makomisheni uye cyclic carbonate makomisheni.Iyo yekutanga inogona kushandiswa kugadzirira inoshanda amino acids uye polypeptide makomisheni, uye iyo yekupedzisira inogona kushandiswa kugadzirira akasiyana emishonga nemishonga yezvipembenene.
