丙醛制备
丙醛虽然有多种制备方法，但直至五十年代初才开始工业生产，1975年美国联合碳化物公司建成以铑-膦为催化剂；由乙烯低压经羰基合成制丙醛的第一个年产4.5万t的大型装置后，低压羰基合成法逐渐成为丙醛生产的主要方法和发展方向。1981年美国；日本和西欧丙醛总生产能力23万t中，95%以上是采用低压羰基合成法生产的。
1.羰基合成法 由乙烯与一氧化碳；氢气经一步反应而成。最初以羰基钴为催化剂，在高压（14.7-19.6MPa）下进行。近年发展了以铑膦络合物为催化剂的合成法，反应温度100℃，压力1.27-1.47MPa。该法无异构体产生，分离简便。
2.环氧丙烷异构化法 1,2-环氧丙烷在铬钒催化剂存在下经气相异构化而得。此外，尚有丙醇氧化法及丙烯醛加氢法等。丙烯以氯化钯为催化剂直接氧化生产丙酮时的0.5-1.5%的副产品丙醛，当提高催化剂中氯化钯含量的反应温度时，丙醛副产的比例可增大到50%。
3.制法：
于装有分馏装置（接受瓶用冰水浴冷却）、滴液漏斗（底部伸入瓶底）的反应瓶中，加入丙醇（2）34g（0.567mol）和几粒沸石，加热至沸。滴加由重铬酸钾56g（0.188mol）、300mL水和40mL浓硫酸配成的溶液，约20min加完。保持反应体系沸腾，分馏柱顶温度不超过75℃，当氧化剂全部加完后，继续反应15min，收集80℃以下的馏分。从镏出液中分出水，无水硫酸钠干燥，分馏，收集47～50℃的馏分，得丙醛（1）12g，收率36%。
