4-硝基肉桂酸制备

1.将对硝基肉桂腈、浓盐酸和水一起加热回流8h，静置过夜。滤出沉淀物，溶于热30%氢氧化钠溶液中，滤除不溶物，滤液用50%硫酸酸化析出沉啶，过滤得粗品，用乙醇重结晶，得对硝基肉桂酸。

2.制法：

于装有搅拌器、回流冷凝器的反应瓶中，加入对硝基肉桂腈（2）20g（0.12mol），300mL浓盐酸和150mL水，搅拌下加热回流反应8h。回流过程中沉淀的盐酸逐渐变为灰色。反应完后室温放置过夜。抽滤。将固体物溶于热的氢氧化钠溶液中，滤去不溶物，再用盐酸调至对刚果红试纸呈酸性。冷却后抽滤，得灰白色固体。用约100mL乙醇重结晶，得对硝基肉桂酸（1）9g，mp283～285℃，收率41%。
