谁合成过这个物质？ 这个东西很便宜的。为什么还要自己做啊？ a 2-liter, 4-necked flask equipped with a stirrer, thermometer, condenser and a dropping funnel having a by-pass was charged with 20.4 g (0.10 mole) of 4-nitrophenyl methyl sulfide, 10 g of water and 200 g of monochlorobenzene. then, 94.5 g (0.70 mole) of sulfuryl chloride was added dropwise at 10.deg. c. over a period of about 2 hours. thereafter the mixture was stirred at 10.deg. c. for 6 hours to complete the reaction. after completion of the reaction, the oil layer was separated and 10 g of water was added to accomplish washing. then, the oil layer was separated and left to stand for about 1 hour with the addition of about 5 g of anhydrous sodium sulfate to remove the water. the solvent was distilled off to give crude crystals. the crude crystals were dissolved in monochlorobenzene and a poor solvent was added for recrystallization, giving 21.1 g of 4-nitrobenzenesulfonyl chloride as white crystals in a yield of 95percent as calculated based on 4-nitrophenyl methyl sulfide.查看更多
