2-亚硝基-1-萘酚合成路线

2-亚硝基-1-萘酚制备

生产方法简介

1.由1-萘酚经亚硝化而得。1.亚硝化将氢氧化钠溶于水后，在搅拦下加入1-萘酚。过滤，滤液保持在0-5℃下，加旱灾亚硝酸钠水溶液，加完再慢慢加入乙酸。然后用1：4的稀盐酸调整pH，使刚果红试纸呈蓝色为止。用淀粉碘化钾试纸控制点，继续搅拌半小时，滤出硝化物，水洗至不呈酸性为止，干燥。2.除去异构物亚硝化还生成4-亚硝基-1-萘酚，可用下法除去即把氢氧化钾溶于酒精后，在搅拌下慢慢加入干燥的硝化物，此时反应温度保持在60℃，加毕，继续搅拌10min。冷却，滤出粗品，加入乙醇浸泡，过滤。最后精制即得成品。

2. 搅拌下将α- 萘酚加到氢氧化钠水溶液中，滤去不溶物。控制滤液温度为0～5℃，依次加入亚硝酸钠溶液和醋酸，然后再用1∶ 4的稀盐酸调狆犎值，使刚果红试纸呈蓝色，用淀粉碘化钾试纸控制反应终点。反应结束后继续搅拌半小时，过滤，然后用水洗涤硝化物结晶至不呈酸性，干燥。将干燥的硝化物结晶在搅拌下慢慢地加到氢氧化钾的乙醇溶液中，保持温度为60℃，之后，继续搅拌10min，静置自然冷却，过滤所得结晶用乙醇浸泡后再过滤，以除去异构物将所得结晶溶于热的蒸馏水中，加入活性炭脱色，搅拌下加入盐酸至滤液ph值为5，析出的沉淀用蒸馏水洗涤一次，再用乙醇重结晶，即得成品。
