1-萘甲醛制备

1.制法：

于装有搅拌器、滴液漏斗、通气导管（伸入反应瓶底部）、回流冷凝器的反应瓶中，加入β-萘甲酰氯（2）57g（0.3mol），200mL金属钠干燥的二甲苯，6gPd-BaSO4催化剂。用氢气置换反应瓶中的空气。于油浴140～150℃、剧烈搅拌下通入氢气，通气速度1～2个气泡/秒。有氯化氢气体逸出（可用碱吸收）。反应约2h完成（可通过检验有无氯化氢逸出来判断）。冷却，滤去催化剂。活性碳脱色。蒸出二甲苯。而后减压蒸馏，收集147～149℃/2.0kPa的馏分，冷后固化，得β-萘甲醛（1）19g，mp59～60℃.收率80%。

2.制法：

于装有搅拌器、滴液漏斗、通气导管、回流冷凝器的反应瓶中，加入无水乙醚400mL，无水氯化亚锡76g。冷却下通入干燥的氯化氢气体，直至饱和，反应液分为两层。搅拌下滴加β-萘甲腈（2）30.6g（0.2mol）溶于200mL无水乙醚的溶液，再通入干燥的氯化氢气体。快速搅拌，而后放置过夜。滤出固体，用乙醚洗涤。将固体物加入另一反应瓶中，加入水，进行水蒸汽蒸馏。馏出液冷却后析出固体。抽滤，干燥，得β-萘甲醛（1）25g，收率80%。减压蒸馏，收集156～158℃/2.0kPa的馏分，冷后固化。mp57～58℃
