【摘要】 研究了浓硫酸用量对正丁醚产率的影响． 采用减压蒸馏分离出粗产品， 重复利用蒸馏残酸溶液与正丁醇反应，可以得到较高产率的正丁醚更多还原

【Abstract】 The effect of quantity of sulfuric acid on the yield of n butylether has been studied. The crude product can be separated from reaction mixture by vacuum distillation. It can give higher yield by reaction of n bytyl alcohol with destillation rasidual acid,which is used repeatedly.更多还原
