福美双 制备方法及用途
制备方法
-
福美钠的制备 二甲胺盐酸盐和二硫化碳在氢氧化钠存在下生成二甲氨基二硫代甲酸钠(福美钠),反应温度50～55℃,pH值为8～9。福美双的制备 福美钠(或福美铵)与双氧水在硫酸存在下生成福美双,温度控制在10℃以下,终点pH值3～4。也可用氯气代替双氧水和硫酸,反应在筛板塔中进行,氯气经稀释从塔底部进入,塔顶喷淋5%福美钠溶液,称氯气-空气氧化法。也可采用亚硝酸钠氧化法或电解氧化法。
合成制备方法
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。
用途简介
-
该品作为农药通常称为福美双，主要用于处理种子和土壤，防治禾谷类白粉病、黑穗病及蔬菜病害。该品作为天然胶、合成胶及胶乳的超促进剂，通常称促进剂TMTD，是秋兰姆硫化促进剂的代表，占同类产品总量的85%。作为天然胶、二烯类合成胶、Ⅱ、R、EPDM的超级促进剂，是利用率最高的一种。硫化促进力非常强，但无氧化锌存在时，则完全不硫化。
用途
1.农业上用作种子杀菌剂、杀虫剂、防霉剂；工业上用作润滑油添加剂。本品是天然橡胶、合成橡胶及乳胶用的超硫化促进剂。常与噻唑类促进剂并用，也可与其他促进剂并用作为连续胶料的促进剂。本品因在100℃以上即缓缓分解，析出游离硫，故可作硫化剂。制品的老化性和耐热性极好。主要用作制造轮胎、内胎、胶鞋、医疗用品、电缆和工业制品等。尤其适用于透明、白色和有色的橡胶工业制品中。在氯丁橡胶中用作硫化延缓剂。
2.属广谱的保护性杀菌剂，残效期达7d左右。主要用于处理种子和土壤，防治禾谷类作物白粉病、黑穗病、稻秧苗立枯病，也可用于一些果树、蔬菜病害。如用50%可湿性粉剂500g拌种，可防治稻瘟病，稻胡麻叶斑病，大麦、小麦黑穗病。
3.用作丁腈橡胶等胶黏剂的促进剂。
4.用于香皂的抑菌剂和除臭剂。农业的杀虫剂。
