丁二烯是合成橡胶的主要原料 ,发展合成橡胶工业的技术关键首先是扩大丁二烯的来源 ,从炼厂气中的正丁烯合成丁二烯。中科院兰州化物所未走美国等催化脱氢生产丁二烯的老路 ,而是大胆探索国际上刚露苗头的丁烯氧化脱氢制丁二烯新反应。与此同时 ,长春应化所对钛、钴、镍等不同 Butadiene is the main raw material of synthetic rubber. The key to the development of synthetic rubber industry technology is firstly to expand the source of butadiene and to synthesize butadiene from n-butene in refinery gas. The Lanzhou Institute of Chemicals of the Chinese Academy of Sciences did not take the old road of catalyzed dehydrogenation to produce butadiene in the United States. Instead, it boldly explored the emerging new phenomenon of butadiene oxide oxidative dehydrogenation to butadiene. At the same time, Changchun Chemical Industry Co., Ltd. is different from titanium, cobalt, and nickel.
