Paragraph 0045-0050, (2020/11/24)
The invention discloses a preparation method of thiomethylbenzene di (thio) cyanate. The method disclosed by the invention adopts a thiol as a nucleophile, converts TNT into a single-sulfur product 2S - T1, 4 S - T1 or any mixture thereof under the action of an additive, and obtains the reduction product 2S - T2, 4 S - T2 or any mixture thereof under the catalytic hydrogenation conditions; further, the target toluene diisopropylthio-cyanate 2S - T3, 4 S - T3 or any mixture thereof is obtained through light gasification. The preparation method provided by the invention has the characteristics of cleanness and high efficiency; the product toluene diisocynate (sulfur) cyanate ester has wide application prospects in the fields such as polyurethane, polycarbonate and the like; and the method provides technical support for recycling TNT in waste ammunition.
