N-乙酰苯胺下游产品

N-乙酰苯胺制备

1.由苯胺经乙酸乙酰化而得。将苯胺和冰醋酸（过量100%）置于带夹套的搪玻璃反应器内，回流6-14h直至无游离苯胺为止。若用稀乙酸，则反应温度为150-160℃，反应结束后趁热过滤，除去残渣，滤液冷却、结晶，离心过滤，水洗并干燥，即得产品。也可采用乙酐作酰化剂，反应在苯溶液中进行，乙酐过量150%。操作示例1将四只反应罐成梯形排列，最高一只反应罐装有分馏柱。苯胺从分馏柱顶部连续加入，回收乙酸与苯胺混合物从第二只反应罐连续加入，乙酸从第三只反应罐连续加入。控制不同的反应温度（第三只为160-170℃，第四只为200-210℃），使乙酸与苯胺进行气液相对流反应，反应生成的水从分馏柱顶部蒸出，乙酰化物流入第四只反应罐，再抽入蒸馏罐，减压蒸出未转化的苯胺及乙酸，反应产物经冷却成片状，得乙酰苯胺。重量配料比：苯胺：乙酸＝1：（0.65-0.70），收率99.5%。操作示例2先向酰化锅投入苯胺及3/10量的乙酸（含量60%以上），加热，同时缓缓加入1/10量乙酸，加热至沸腾，收集分馏出的稀乙酸，并缓缓向锅内补充4/10量的浓乙酸或冰醋酸，反应7h。最后一次加入剩余的2/10量的冰醋酸，回流分馏，当分馏出的乙酸浓度达85%以上时，进行真空蒸馏，蒸出剩余的乙酸。出料、冷却、粉碎即为成品。苯胺酰化生产乙酰苯胺大多采用冰醋酸作酰化剂。原料消耗定额：苯胺（99%）690kg/t、冰醋酸500kg/t。实验室制备可按下法：在带回流冷凝器的500ml烧瓶中，加入20.5g（0.22mol）苯胺，21.5g（0.21mol）乙酐，21g（0.35mol)冰醋酸及0.1g锌粉。混匀后缓缓加热煮沸半小时。然后将热反应物呈细流状傾入500ml冷水中，搅拌，用冰冷却。过滤，干燥，得粗品26g。熔点113℃。用乙醇、水重结晶提纯，熔点114℃。
