异丁醇制备
丁醇丙烯羰基合成法分为高压法、中压法和低压法。高压羰基合成技术由于选择性较差、副产品(丙烷和高沸物)多，已被以铑为催化剂的低压羰基合成技术所取代。
就世界范围而言，目前具有竞争力的羰基合成技术有鲁尔-化学的中压技术以及伊士曼、三菱化成和戴维的低压技术。中压的鲁尔-化学技术消耗最低，技术水平最高，但因工业推广晚，目前世界上采用该技术的装置能力仅占世界羰基合成能力的9%。伊士曼技术具有产品可依市场灵活调节的优点，但没有成套技术转让的经验。戴维技术自20世纪70年代以后便在世界迅速发展，在美国、瑞典、日本、波兰、匈牙利、南朝鲜、德国等欧亚及北美地区就有13套装置应用该种专利技术。戴维的铑法工艺技术占低压羰基合成技术总能力的69%，在世界羰基合成工业中占领先地位。
1.羰基合成法（丙烯制丁醇时的副产品） 以丙烯与合成气为原料，经羰基合成制得正、异丁醛，脱催化剂后，加氢成正、异丁醇，经脱水分离，分别得成品正、异丁醇。
2.异丁醛加氢法 异丁醛在镍的催化下，进行液相加氢反应，制得异丁醇。
3.从生产甲醇厂副产的异丁基油中回收 合成甲醇精馏的副产物--异丁基油，经脱甲醇、盐析脱水，再经共沸精馏，得异丁醇。
4.以工业品异丁醇为原料，加入氧化钙脱水干燥，5h后蒸出异丁醇，馏出液再经精馏，得纯品。与环己烷共沸精馏，可制得无水异丁醇。
