摘要
一步法顺酐加氢生产丁二酸酐的最佳条件为:加氢压力1~1.6MPa,反应温度50-100℃,反应时间1-2h,骨架镍催化剂用量是顺酐用量的4%-6%,搅拌速度300r/min,在此条件,丁二酸酐的最高收率可达90%以上。
The best condition for manufacturing succinic anhydride from maleic anhydride by one step way is: pressure of hydrogenation 1- 1.6 MPa, reaction temperature 50-100℃, reaction time 1 - 2 h. The amount of catalyst remains 4%-6% of maleic anhydride, stiring speed keeps 300 r/min. Under this condition,the yield of suecinic anhydride can be more than 90%.
