Yintoni i-pharmaceutical intermediates?

I-Pharmaceutical intermediates, ngokufutshane, zizinto zemichiza ekrwada okanye iimveliso zekhemikhali ezisetyenziswa kwinkqubo yokudibanisa amayeza. Ziimveliso ezineempawu ezikhethekileyo ezenziwe ngokusabela kweekhemikhali ezimbini okanye ngaphezulu ezahlukeneyo zemathiriyeli ekrwada ngokwemilinganiselo efanelekileyo. Ezi ziphakathi ziyafana kodwa zahlukile kwisakhiwo sekhemikhali, njenge-ethyl acetate kunye ne-n-butyl propionate, i-methyl methacrylate kunye ne-methyl acrylate, njl. njengozinzo, ukunyibilika, njl.njl Uphawu olubalulekileyo lwabaphakathi bamayeza kukuba nangona bedlala indima ebalulekileyo kwinkqubo yokuvelisa amachiza, abafuni mvume yokuvelisa ichiza. Oku kuthetha ukuba zinokuveliswa kwizityalo eziqhelekileyo zeekhemikhali kwaye, nje ukuba zihlangabezane nemigangatho ethile yemigangatho, zingasetyenziselwa ukudibanisa amayeza. Kuyafaneleka ukuba uqaphele ukuba i-pharmaceutical intermediates ngokuqhelekileyo ibiza kakhulu, ehambelana neenkqubo zabo zokuvelisa eziyinkimbinkimbi kunye neemfuno ezingqongqo zomgangatho. Kodwa kobu buntsonkotha kunye nobuchule obenza ukuba abaphakathi bamayeza bathathe indawo ebaluleke kakhulu kwishishini loxubo mayeza. Ukongeza, abaphakathi bamayeza bayinxalenye ebalulekileyo yeshishini lamayeza laseTshayina. Emva kwamashumi eminyaka yophuhliso, izinto zemichiza ekrwada kunye neziphakathi ezifunekayo kwimveliso yamayeza eTshayina ziye zadityaniswa ngokusisiseko, kwaye inxenye encinci kuphela ekufuneka ingeniswe kumazwe angaphandle. Ngaphezu koko, ngenxa yobutyebi obuninzi belizwe lam kunye namaxabiso aphantsi ezinto eziphathekayo, abaninzi abalamleli baye bathunyelwa kumazwe angaphandle ngezixa ezikhulu, bezuza udumo lwamazwe ngamazwe kwishishini lelizwe lam loxubo-mayeza.

Ngokubanzi, abaphakathi bamayeza bayinxalenye ebalulekileyo yekhonkco loshishino lwamayeza. Ngeempawu zabo zeekhemikhali ezikhethekileyo kunye neenkqubo zokuvelisa, babonelela ngesiseko esiqinileyo sezinto eziphathekayo ekwenzeni amachiza kwaye baye benza igalelo elibalulekileyo kwimpilo yabantu. negalelo.
