代森钠制备

其制备方法是在反应釜中预先加入清水，在搅拌下加入乙二胺，控制反应温度小于35℃开始滴加二硫化碳，滴加完毕，保持反应物料温度在30℃左右继续搅拌30min，待反应物料的介质pH≤9时，开始分批向反应釜加入20%氢氧化钠水溶液，加碱时反应温度控制在35℃左右，每批加氢氧化钠后控制反应液的pH≤9后，才能加下一批氢氧化钠。在全部氢氧化钠加完后，继续保温反应1h，取样观察物料中已无明显油珠即为达到反应终点，降温至25℃以下，停止搅拌，静置，将未反应的二硫化碳分离出来，所得淡黄色液体即为代森钠水溶液。

代森钠的合成有一步法和两步法，国内均采用两步法，此法有利于控制副产物三硫代碳酸钠的生成，因此产品质量好，收率亦高。
