General description
苯甲醛（苦杏仁油）是一种常用的芳香族化合物，主要用于化妆品和香料工业。苯甲醛的天然来源是苦杏仁苷，一种存在于杏子、苦杏仁、苹果、樱桃中的糖苷。苯甲醛是通过液相氯化和甲苯氧化生成。其他已报道的苯甲醛生产方法包括苯甲醇氧化法、苯甲醛氯水解法和苯羰基化法。
Application
苯甲醛可用作合成以下成分的前体：
- 肉桂醛、肉桂酸、肉桂酸乙酯、苯甲酸、苯甲醇、苯甲酸苄酯和三亚苄二胺等。
- 通过与酚类、芳香胺类和苯的缩合生成的三苯甲烷衍生物。该反应可用于孔雀石绿染料的生产。
- 与硼酰溴化镁反应的苯甲酰硼烷。
- 多苯甲醛功能化聚乙二醇类似物作为交联剂开发可注射水凝胶体系。
