该化合物是硫代丙酮(丙烷-2-硫酮)的稳定的环状三聚物,而硫代丙酮本身是一个不稳定的化合物[4][5]。相比之下,与之类似的化合物三丙酮(2,2,4,4,6,6-六甲基-1,3,5-三噁烷,氧原子代替硫原子)是不稳定的,而单体丙酮(2-丙酮)本身是稳定的。
制备
三硫丙酮最早由欧根·鲍曼(Eugen Baumann)和E·弗罗姆(E. Fromm)于1889年通过硫化氢与丙酮的反应而合成[5]。在25℃、酸性、有ZnCl
2催化剂的条件下,得到的产物是60%-70%的三硫丙酮,30%-40%的2,2-丙二硫醇,以及少量的两种异构体杂质3,3,5,5,6,6-六甲基-1,2,4-三硫雜環己烷和4-巯基-2,2,4,6,6-五甲基-1,3-二硫雜環己烷[5]。该产品也可以通过烯丙基异丙基硫醚(3-异丙硫基丙-1-烯)的热解来获得[6][7]。
反应
三硫丙酮在500-650℃和5-20 mmHg下热解产生硫丙酮,可通过−78℃的冷阱收集。
