正戊醇制备
1.戊烷混合物光氯化法 戊烷馏分经无水氯化氢脱水后与氯气混合，温度120-300℃，产物经冷却、精馏，再以油酸钠作催化剂，用氢氧化钠水溶液使氯代戊烷水解，粗戊醇与水分离，蒸馏可得含伯醇59%，仲醇36%、叔醇5%的的戊醇。据报道，美国主要采用此法生产。
2.碳四烯烃羰基合成法 碳四烯烃用65%硫酸处理后，以钴盐为催化剂进行羰基化，水煤气压力14.7-19.6MPa，反应温度140-170℃。羰基化反应物用氢气或稀硫酸处理，使羰基钴分解为金属钴，在17.7-19.6MPa的氢压下，温度180-200℃以下还原，再经分离精制而得戊醇。
杂质除水分外，还含有少量异戊醇等异构体。精制时用无水碳酸钾或无水硫酸铜干燥，过滤，分馏。也可用1%~2%的金属钠处理，加热回流15个小时以除去水和氯化物。微量的水可用少量的金属钠在2%~3%的邻苯二甲酸二戊酯或丁二酸二戊酯存在下，加热回流后再蒸馏除去。欲得高纯度的戊醇可以用羟基苯甲酸酯化，二硫化碳重结晶，再用氢氧化钾醇溶液皂化，硫酸钙干燥后分馏。此外也可加入5%~10%的苯进行共沸蒸馏除去戊醇中的水分。
3.以工业品正戊醇为原料，先用无水碳酸钠或硫酸钙脱水干燥，过滤后精馏，常压下收集137～139℃馏分，即得纯品。
4制法：
于装有搅拌器、温度计、回流冷凝器的反应瓶中，加入戊酸乙酯(2)130g(1.0mol),无水乙醇2000mL，搅拌下分批加入新鲜金属钠(切成小块)238g(10.25mol),加入速度保持反应液剧烈回流。加完后继续回流1h，以使金属钠完全反应。安上分馏装置，蒸出乙醇约700mL。加入水800mL，继续油浴加热分馏，直至分馏柱顶端温度达到83℃，表明乙醇己基本蒸完，约瘦集大约90%的乙醇1500mL。撤去分馏装置，进行水蒸汽蒸馏，大约收集600mL的溜出液，1-戊醇基本蒸完。分出粗戊醇，无水碳酸甲干燥，分馏，收集137～139℃的馏分，得1-戊醇(1)63g，收率71%。
