2-乙基苯胺

2-乙基苯胺用途

【用途一】
是重要的农药、染料及医药中间体，农药方面是合成新型杀虫剂的关键中间体
【用途二】
邻乙苯胺与2-溴丙烷进行N-烷基化反应后，再用氯乙酸-三氯化磷直接酰化，可制得杀草胺。这是一种对禾本科杂草及某些阔叶杂草除效果好的苗前选择性除草剂。邻乙苯胺也是灭草胺及杀虫剂乙基杀虫脒的原料。在染料工业方面，本品可用于制造硫化耐晒蓝。

2-乙基苯胺制备

1.生产方法：由邻硝基乙苯还原而得。1.铁粉还原法利用该方法每生产1t产品原料消耗为：邻硝基乙苯（100%）1.66t，氯化铵（工业品）350kg、烧碱（100%）160kg、铁粉（工业品）1.65t、精盐（工业品）1.4t。2.硫化钠还原法硫化钠和邻硝基乙苯在120-130℃下反应，将反应混合物分离后得产品，产品收率95%。

包装采用小开口钢桶，螺纹口玻璃瓶、铁盖压口玻璃瓶、塑料瓶或金属桶（罐）外木板箱。贮存于阴凉、通风仓间内。远离火种、热源。贮存期不可太长，规定三个月轮换一次。保持容器密封。应与氧化剂、酸类、食品化学品分开存放。搬运时要轻装轻卸，防止包装及容器损坏。
