Chaw tsim tshuaj paus tus nqi p-toluenesulfonyiryananate (PTSI) CAS 4083-64-1

Chaw tsim tshuaj paus tus nqi p-toluenesulfonyLisocyananate (PTSI) CAS 4083-64-1 featured duab

Cov lus piav qhia luv luv:

P-Toluenesulfoningulfonyocyananate (PTSI) yog ib qho haujlwm ortocyanate. P-ToluenesulfoningulfonYocyananate (PTSI) muaj kev ua haujlwm siab thiab muaj peev xwm ua rau muaj txiaj ntsig zoo, xws li TDI thiab HDI, nrog dej hauv polyols thiab cov kuab tshuaj. Lub resulting carbamate tsis nce viscosity ntawm lub system. Qhov tsis zoo yog qhov lom ntawm oxazolidine thiab lwm yam dej nyab yog loj; P-ToluenesulfoningulfonYocyananate (PTSI) reacts nrog dej los tsim cov pa roj carbon dioxide, yog li ptsi) tsis tuaj yeem siv ncaj qha rau hauv cov xim ua kom ncaj thiab feem ntau yog siv rau cov dej qhuav. Txhawm rau tshem tawm 1G dej hauv cov kuab tshuaj, txog 12G ntawm PTSI yog qhov xav tau, tab sis tus nqi tiag tiag yuav tsum tau siab dua qhov no.
