芳香硫醚是一类重要的有机化合物,某些芳香族混合硫醚如对氯苯基对氯苄基硫醚,对溴苯基对溴苄基硫醚等是优良的杀螨剂。另外一些硫醚如二苄基硫醚,苯基苄基硫醚是高聚物如聚乙烯的有效抗氧剂。硫氰酸酯如2,4—二硝基苯基硫氰酸酯(商品名为二消散)等是优良的杀菌剂,能防治许多农作物的各种病害。因此研究探讨合成芳香族硫醚和硫氰酸酯的新方法,以提高生产能力,对工农业生产有着重要的现实意义。
Aromatic thioethers are an important class of organic compounds. Some aromatic mixed sulfides, such as p-chlorophenyl p-chlorobenzyl sulfide and p-bromophenyl p-bromobenzyl sulfide, are excellent acaricides. Additional thioethers such as dibenzylsulfide and phenylbenzylsulfide are effective antioxidants for polymers such as polyethylene. Thiocyanates such as 2,4-dinitrophenylthiocyanate (trade name II dissipates) are good bactericidal agents that can prevent many diseases of many crops. Therefore, it is of great practical significance to study new methods of synthesizing aromatic thioethers and thiocyanates in order to increase the production capacity and to make industrial and agricultural production.
