At present , aniline and acetone are used as raw materials in the production of RD , condensed at 150-165 ℃ in the presence of sulfinic acids , polymerized in hydrochloric acid solutions .

目前，RD的生产方法是采用苯胺和丙酮为原料，苯磺酸为催化剂，在150～165℃下进行缩合反应，然后在盐酸介质中聚合而成聚合物，在氢氧化钠溶液中析出。

Initial reaction of alcohols with sulfinyl chlorides yield sulfinate esters that are ready to decompose in the presence of byproduct HCl , and the resulting carbocations and sulfinic ' acids are coupled to afford sulfones .

醇和亚磺酰氯反应生成亚磺酸酯，然后在副产物氯化氢的催化下生成碳正离子和亚磺酸，两者结合便生成砜。
