wehewehe pōkole:

ʻO P-TOLUENESULFONYLISOCYANATE (PTSI) kahi isocyanate hana hoʻokahi. Loaʻa iā P-TOLUENESULFONYLISOCYANATE (PTSI) ka hana kiʻekiʻe a hiki ke hana me nā diisocyanates maʻamau, e like me TDI a me HDI, me ka wai i loko o nā polyols a me nā solvents. ʻAʻole hoʻonui ka carbamate hopena i ka viscosity o ka ʻōnaehana. ʻO ka hemahema, ʻo ia ka nui o ka ʻawaʻawa o ka oxazolidine a me nā dehydrants ʻē aʻe; Hana ʻo P-TOLUENESULFONYLISOCYANATE (PTSI) me ka wai e hana i ke kalapona dioxide a me toluenesulfamide, no laila ʻaʻole hiki ke hoʻohana pololei ʻia ʻo P-TOLUENESULFONYLISOCYANATE (PTSI) i nā ʻano pena a hoʻohana pinepine ʻia no ka pre-dehydration. No ka wehe ʻana i ka 1g o ka wai i loko o ka solvent, ma kahi o 12g o PTSI e pono ai ke kumumanaʻo, akā ʻoi aku ka nui o ka nui maoli ma mua o kēia.
