二正丁胺

二正丁胺用途

【用途一】
用于石油添加剂、橡胶促进剂、矿物浮选剂、腐蚀抑制剂、乳化剂、杀虫剂、阻聚剂及染料等
【用途二】
用于有机合成，也用作橡胶硫化促进剂和抗腐蚀剂
【用途三】
二正丁胺是一种有机合成原料，在农药上可用来合成丁硫克百威，还可用于染料、橡胶硫化促进剂(BZTP)、防老化剂(NBC)、POP聚合催化剂、抗腐蚀剂、药物以及油品添加剂二丁基二硫代氨基甲酸盐(钼、铅、锑、锌)的生产。
【用途四】
作用机合成中间体。用于染料、橡胶硫化促进剂、抗腐蚀剂、药物、油品添加剂的生产。该品有毒，小鼠口服LD50550mg/kg。用二丁胺生产二硫代氨基甲酸盐类促进剂，例如，二丁基二硫代氨基甲酸锌（促进剂BZ）是由促进剂TP与ZnCI2经置换而得的。而促进剂TP（二丁基二硫代氨基甲酸钠）是由二丁胺与二硫化碳和氢氧化钠反应得到的。这类产品属超促进剂，因焦烧时间太短，一般用于胶乳生产。促进剂TP与NiSO4反应可得防老剂NBC。该品在天然橡胶、丁苯、氯丁等合成橡胶中防护热、臭氧、天候的老化。二丁基二硫代氨基甲酸盐（钼、铅、锑），例如二丁铅。用作石油添加剂，有抗氧化、抗磨、抗极压的功能。促进剂TP用氧化剂铁氰化钾在低于0℃条件下氧化而生成二硫化四丁基秋兰姆。也是天然橡胶及合成橡胶的超促进剂，亦可作硫化剂。
【用途五】
用于生产医药、农药、染料、矿物浮选剂、乳化剂以及精细化学品的中间体等。用作腐蚀称职制剂，橡胶促进剂，杀虫剂，阻聚剂等。

二正丁胺制备

二正丁胺有两种生产方法。
1.正丁醇法
由正丁醇与氨作用而得。反应方程式如下：n-C₄H₉OH+NH₃+H₂→n-C₄H₉NH₂+(n-C₄H₉)₂NH+(n-C₄H₉)₃N
工艺过程为：将正丁醇、氨气、氢气经流量计控制，按配比通入不锈钢反应塔，塔内填充铜镍酸性白土催化剂，反应温度在200℃左右。反应结束后将反应气体冷凝，得到的粗产品含一丁胺2%～4.82%、二丁胺17%～26%、三丁胺31%～61%，通过精馏分离可得一丁胺、二丁胺和三丁胺。

2.石灰氮(氰氨化钙)法
反应方程式如下：CaCN[NaOH]→Na₂NCN[C₄H₉Br]→(C₄H₉)₂NCN[H₂O]→[H₂SO₄](C₄H₉)₂NH
工艺过程为：将石灰氮悬浮在冰水中，慢慢加入冷却的氢氧化钠溶液，温度保持在25℃以下，剧烈搅拌1h，得到氰氨化钠溶液。向此溶液中加入溴丁烷乙醇溶液，搅拌回流2.5h，然后进行蒸馏，将剩余物冷却吸滤，滤饼用乙醇洗涤，将滤液和洗液合并，用苯萃取，将萃取液用无水硫酸钙干燥，经蒸除苯后将剩余物减压蒸馏，收集147～151℃/4.66kPa馏分，得二丁基氰胺。依次将水和浓硫酸、二丁基氰胺加入反应器，缓慢回流6h，冷却，沿器壁倒入冷却的氢氧化钠溶液(流至反应器底部而不与反应物料混合)，使游离胺分离；然后加热，将胺和水一起蒸出。向馏出物中加入粒状氢氧化钾，并用冰冷却，分出胺层，干燥，蒸馏，收集157～160℃馏分得成品。
