从乙烯基乙炔加氯化氢制备氯丁橡胶单体2-氯丁二烯-1,3时,得到副产品1,3-二氯丁烯-2约5％~([1])。此副产物至今尚未充分利用。目前我国年产氯丁橡胶约一万吨,每年有五百吨左右副产物。若能将其利用,不仅可防止环境污染,同时也可为国家节约资金。本文将1,3-二氯丁烯-2制成正丁胺。丁胺可用作裂化汽油防胶剂、石油产品添加剂、彩色相片显影剂,也可用于制杀虫剂、制治精尿病药物,乳化剂等~([2])。 Chlorinated rubber monomer 2-chlorobutadiene-1, 3 was prepared from vinylacetylene and hydrogen chloride to obtain 5% ~ ([1]) byproduct 1,3-dichlorobutene-2. This by-product has not yet been fully utilized. At present, China has an annual output of about 10,000 tons of neoprene, about 500 tons of by-products each year. If they can be used, not only to prevent environmental pollution, but also for the country to save money. In this paper, 1,3-dichlorobutene-2 ​​is made of n-butylamine. Butylamine can be used as a cracked gasoline anti-sealant, petroleum products additives, color photo developer, but also can be used for insecticides, the treatment of fine diabetes drugs, emulsifiers and so on ~ ([2]).
