甲基庚烯酮制备

1、乙炔丙酮法以乙炔、丙酮为原料首先制得甲基丁炔醇，后者还原成烯醇后与乙酰乙酸乙酯或二乙烯酮反应得甲基庚烯酮。

2、异丁烯法以异丁烯为原料，与丙酮和甲醛在250℃、30MPa条件下一步合成α-甲基庚烯酮，然后在钯、羰基铁催化剂作用下加热转化得到甲基庚烯酮。以异丁烯、丙酮及甲醛为原料一步法合成得到甲基庚烯酮。在反应压力30MPa、反应温度310~320℃，异丁烯：丙酮：甲醛为5：4：1（摩尔比），反应停留时间115h的反应条件下，得到甲基庚烯酮的收率达34%（以进料甲醛为基准），时空收率达35g/（h·L）。研究结果表明，添加磷酸或烧碱均不能起到催化作用，反应温度越低，α-甲基庚烯酮与β-甲基庚烯酮的比值越高。由于该工艺是三分子之间的缩合反应，副反应较多，产品分离纯化要求较高。

3、异戊二烯法该法由法国Rhodia公司首先提出，以异戊二烯为原料，与盐酸作用生成异戊烯氯，后者与丙酮反应成本品，是在无水体系中进行间歇反应过程。目前，Rhodia法已停止使用。日本可乐丽公司对该工艺进行了改进，采用季铵盐为相转移催化剂，在氢氧化钠水溶液中进行连续反应，该公司建有生产装置。
