叔戊醇下游产品

叔戊醇制备

1. 以丙酮、乙炔为原料，经炔化，加氢而得。将乙炔溶于液氨中，与丙酮、催化剂混合后送入炔化反应器，反应液经闪蒸，分出未反应的乙炔和氨，蒸出未反应的丙酮，得到的甲基丁炔醇进入加氢反应器反应，生成叔戊醇，经脱水、精制而得产品。

2. 由异戊烯加水而成。

3. 用由戊烷经氯化和水解后生成的混合醇分馏制得。原料戊烷先用无水氯化氢脱水，蒸发后与氯气混合进入反应器，反应温度为250-300℃。反应生成物经四个精馏塔精馏分离得到氯戊烷。在水解器中以油酸钠为催化剂，用氢氧化钠水溶液使氯戊烷水解，粗戊醇与水分离、蒸馏可得含伯醇59%、仲醇36%、叔醇5%的戊醇。采用以丙酮和乙炔为原料的方法，可获得纯度为99%的产品。原料消耗定额：丙酮1040kg/t、电石1500kg/t、氢气（99.5%）650m3、液氨135kg/t、碳酸钾340kg/t。

精制方法用无水碳酸钾、氧化钙、氢化钙或金属钠回流后分馏。

4.制法：

由丙酸乙酯(2)102g(1.0mol)和由49g(2mol)铁屑与284g(2.0mol)碘甲烷反应制备的碘化甲基镁作用，按上述2-甲基-2-戊醇的操作方法，收集100～102℃的馏分，得2-甲基-2-丁醇(1)。
