nkowa nkenke:

P-TOLUENESULFONYLISOCYANATE (PTSI) bụ otu isocyanate na-arụ ọrụ. P-TOLUENESULFONYLISOCYANATE (PTSI) nwere ọrụ dị elu ma nwee ike imeghachi omume na diisocyanates omenala, dị ka TDI na HDI, na mmiri na polyols na ihe mgbaze. Ihe na-esi na carbamate adịghị eme ka viscosity nke usoro ahụ dịkwuo elu. Ihe ọghọm bụ na nsi nke oxazolidine na mmiri mmiri ndị ọzọ dị ukwuu; P-TOLUENESULFONYLISOCYANATE (PTSI) na-eji mmiri emeghachi omume iji mepụta carbon dioxide na toluenesulfamide, yabụ enweghị ike iji P-TOLUENESULFONYLISOCYANATE (PTSI) mee ihe ozugbo n'ụdị agba ma a na-ejikarị ya eme ihe tupu mmiri gwụ ya. Iji wepụ 1g mmiri n'ime ihe mgbaze, ihe dị ka 12g nke PTSI ka a chọrọ n'ụzọ doro anya, mana ego ole kwesịrị ịdị elu karịa nke a.
