防焦剂CTP

防焦剂CTP用途

【用途一】
主要用于天然橡胶、合成橡胶，尤其与次磺酰胺类促进剂并用时，构成良好的硫化体系
【用途二】
该品是一种很有效的防焦剂，对所有的硫磺硫化的二烯类和低不饱和度的橡胶，如天然胶、丁苯胶、丁腈胶、丁基胶、氯丁胶、异戊胶、顺丁胶、三元乙丙胶等均具有良好的防焦烧效果，而且和其他橡胶助剂配合使用时其活性不受影响。没有发泡、污染等不良的副作用。能大幅度提高胶料的贮存稳定性，防止存放期间发生自然硫化。与以往的防焦剂相比，效果好，用量少，通常的用量是0.1-0.5份。

防焦剂CTP制备

1.由酞酰亚胺与环己基次磺酰氯反应而得。也可由二环己基二硫化物经氯化后与酞酰亚胺缩合。

2.环己硫醇的合成　将环己醇、硫脲和氢溴酸（40%含量）按1:1:25的摩尔比加入反应器中，升温至100℃搅拌回流50h以上得环己基硫脲。然后按氢溴酸量加入50%含量的氢氧化钠水溶液，加热水解2～3h，得硫酚钠。再加入硫酸搅拌下进行酸化，酸化结束停止搅拌，静置分层。油层用无水硫酸钠干燥，经减压蒸馏，收集53～55℃（2.667kPa）馏分即得环己硫醇。反应式如

3.环己基次磺酰氯的合成　环己硫醇在光照下通入氯气进行氯化反应，即

4.缩合反应　上述制备的环己基次磺酰氯在三乙胺存在下，同邻苯二甲酰亚胺缩合，反应温度在0～5℃，即可制得防焦剂CTP
