三硫丙酮（2,2,4,4,6,6-六甲基-1,3,5-三噻烷），也稱三聚硫代丙酮，是一種有機物，化學式為C

3。該化合物可以被看作是1,3,5-三硫雜環己烷的衍生物，即一個碳原子和硫原子交替出現的六元環，每個碳再連接兩個甲基，由甲基取代所有的氫原子^[3]^[1]。

該化合物是硫代丙酮（丙烷-2-硫酮）的穩定的環狀三聚物，而硫代丙酮本身是一個不穩定的化合物^[4]^[5]。相比之下，與之類似的化合物三丙酮（2,2,4,4,6,6-六甲基-1,3,5-三噁烷，氧原子代替硫原子）是不穩定的，而單體丙酮（2-丙酮）本身是穩定的。

製備

三硫丙酮最早由歐根·鮑曼（英語：Eugen Baumann）（Eugen Baumann）和E·弗羅姆（E. Fromm）於1889年通過硫化氫與丙酮的反應而合成^[5]。在25℃、酸性、有ZnCl
2催化劑的條件下，得到的產物是60%－70%的三硫丙酮，30%－40%的2,2-丙二硫醇，以及少量的兩種異構體雜質3,3,5,5,6,6-六甲基-1,2,4-三硫雜環己烷和4-巰基-2,2,4,6,6-五甲基-1,3-二硫雜環己烷^[5]。該產品也可以通過烯丙基異丙基硫醚（3-異丙硫基丙-1-烯）的熱解來獲得^[6]^[7]。

反應

三硫丙酮在500－650℃和5－20 mmHg下熱解產生硫丙酮，可通過−78℃的冷阱收集。

用途

三硫丙酮存在於一些香料中。其FEMA編號為3475。^[8]^[9]^[10]^[11]
