<p>1.由对硝基苯乙腈水解而得。将对硝基苯乙腈、浓硫酸和水混合,加热回流15min。再把反应物倒入冰水中,析出结晶,过滤,用冰水洗涤滤饼,再用水重结晶,即得对硝基苯乙酸。收率92%以上。 <br>2.制法: 于装有搅拌器、回流冷凝器的反应瓶中,加入水150mL,慢慢加入浓硫酸150mL。而后加入对硝基苯乙腈<br>(2)50g(0.3mol),搅拌下加热回流反应0.5h。反应完后,加入等体积的水,冷却后抽滤析出的液体。用约1000mL热水重结晶,活性炭脱色,趁热过滤,冷却析晶。抽滤,水洗,干燥,得浅黄色针状结晶对硝基苯乙酸<br>(1)53g,mp151～153℃,收率95%。 </p> | |
