Isingeniso

I-4-Methyl-5-vinylthiazole iyinhlanganisela yezinto eziphilayo,

 

Izinto ezibonakalayo ze-4-methyl-5-vinylthiazole zifaka uketshezi olungenambala olunephunga elingavamile le-thiol. Iyancibilika kuzincibilikisi zemvelo njenge-ethanol ne-ether futhi ayincibiliki emanzini.

Ibuye isetshenziswe ekwenzeni ama-catalysts nezinto ze-polymer.

 

Ukulungiswa kwe-4-methyl-5-vinylthiazole kuhilela i-vinyl thiazole, ebuye iphendule nge-methyl sulfide ukuze kutholwe umkhiqizo ohlosiwe. Indlela ethile yokulungiselela ingakhethwa ngokuya ngezidingo kanye nobumsulwa obudingekayo.

Kungacasula futhi kudle emehlweni nasesikhumbeni, futhi izibuko zokuzivikela namagilavu ​​kufanele kugqokwe ngesikhathi sokusebenza. Iphinde ivuthe futhi kufanele igwenywe emazingeni okushisa aphezulu kanye nemithombo yokuthungela.
