Abstract
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 succinic anhydride can be more than 90%.
