乙腈市场需求情况与技术分析

Analysis on market demand and production technologies of acetonitrile

介绍了乙腈的用途及市场需求情况,综述了国内外合成乙腈的主要工艺方法,在与乙酸氨化路线、乙醇氨氧化路线对比分析的基础上,着重分析了乙醇脱氢氨化法合成乙腈技术,结果表明,用乙醇作为原料直接合成乙腈,原料相对易得、价格低廉,设备腐蚀性小,并且可以副产氢气。从长远来看,只要开发出高效的催化剂,乙醇脱氢氨化合成乙腈技术更有工业应用前景。

The application and market demand of acetonitrile are presented, and the domestic and overseas advances in production technonlgies of acetonitrile are reviewed. Based on comparing with ammonolysis of acetic acid and ammoxidation of eth anol, the synthesis of acetonitrile by ethanol dehydrogenation ammoniation is analyzed emphatically, owing to easily available and cheap raw materials, slight corrosion to equipment and by-produced hydrogen gas. In the long term, as long as the high efficient catalyst is developed, the industrial prospects of synthesis of acetonitrile by ethanol dehydrogenation amination wilt be more promising.
