P-TOLUENESULFONYLISOCYANATE (PTSI)

P-TOLUENESULFONYLISOCYANATE (PTSI) is a single functional isocyanate. P-TOLUENESULFONYLISOCYANATE (PTSI) has high activity and can react with conventional diisocyanates, such as TDI and HDI, with water in polyols and solvents. The resulting carbamate does not increase the viscosity of the system. The disadvantage is that the toxicity of oxazolidine and other dehydrants is large; P-TOLUENESULFONYLISOCYANATE (PTSI) reacts with water to produce carbon dioxide and toluenesulfamide, so P-TOLUENESULFONYLISOCYANATE (PTSI) cannot be used directly in paint formulations and is generally used for pre-dehydration. To remove 1g of water in the solvent, about 12g of PTSI is theoretically required, but the actual amount should be higher than this.
