2-乙基己醇下游产品

2-乙基己醇制备

1. 羰基合成法　以丙烯和合成气为原料，经羰基合成反应生成丁醛，两分子丁醛经缩合脱水得2-乙基（-2-）己烯醛，再经加氢得2-乙基（-1-）己醇。

2. 乙醛缩合法　以乙醛缩合成丁醇醛，脱水得巴豆醛，加氢得正丁醛，然后将两分子正丁醛缩合脱水得2-乙基（-2-）己烯醛，再加氢得2-乙基（-1-）己醇。 3. 还可以采用铑催化剂催化庚烯羰化一步制辛醇，铑系催化剂Rh2AcO4和[RH（NH3）5Cl]Cl2均可用作反应的催化剂前体（使用时要在催化剂中加入磷，如三丁基膦使催化剂活化，从而使主要产物为正构醇，而不是醛）。 4. 也使用椰子油为原料，在铜-铬催化剂的存在下高压虽氢得到。 5. 乙醛缩合法是先由两分子乙醇缩合生成丁醇醛；然后脱水生成丁烯醛(巴豆醛),丁烯醛经加氢得正丁醛;正丁醛再加氢得正丁醇；如经缩合脱水则生成2-乙基己烯醛，进一步加氢即得到最终产品2-乙基己醇。或者采用高压羰基合成法，以丙烯、一氧化碳和氢为原料，以四羰基氢钴为催化剂进行反应合成正丁醛和异丁醛。正丁醛和异丁醛以铜或镍为催化剂进行加氢反应。正丁醛以气相或固相加氢生成正丁醇；再经初馏后，于两塔蒸馏系统内提纯得到正丁醇。以氢氧化钠为催化剂使正丁醇进行缩合、脱水制得2-乙基己烯醛。2-乙基己烯醛加氢在镍催化剂存在下，在一定温度和压力下加氢制得异2-乙基己醇。
