二硫化四甲基秋兰姆上游产品

二硫化四甲基秋兰姆下游产品

1、二甲基二硫代氨基甲酸钠的制备在15%的氢氧化钠溶液中，加入二硫化碳和二甲胺，搅拌下控制反应温度在40～45℃，缩合反应1h以上，当pH值为9～10时反应已完全，生成二甲基二硫代氨基甲酸钠。

2、促进剂TMTD的制备在缩合产物中加入10%的亚硝酸钠水溶液，搅拌溶解后，经过滤，加入到氧化反应器中，缓缓滴入硫酸，通入空气，控制温度在8℃左右，进行氧化反应，生成促进剂TMTD。促进剂TMTD在反应体系中，以固体析出。经吸滤、水洗、脱水、干燥、筛分，即得成品。

3.在反应釜中加入二甲胺和事先溶解在溶剂中的催化剂，在此溶剂中加入二硫化碳，加热至适宜温度，搅拌下通入氧气反应。一定时间反应完全后，经过滤、洗涤、干燥即得成品。

4.在三颈瓶中加入9g(0.2mol)二甲胺和0.23g催化剂，20℃以下搅拌，滴加18.04g(0.24mol)二硫化碳，继续搅拌后，滴加30%氢氧化钠26.8g(0.2mol)，此时溶液呈淡黄绿色，除去多余二硫化碳，25～40℃滴加次氯酸钠氧化，抽样检验终点，抽滤，水洗至中性，烘干，即得成品。
