By constructing a micro catalytic distillation tower and using Hβ zeolite as catalyst,the reaction of lactic acid and n-butanol in the catalytic distillation tower to produce n-butyl lactate and water was studied.The experiment investigated the effects of different acid alcohol feed ratios,lactic acid feed space velocity,reflux ratio,and feed position on the esterification process,and selected the optimal reaction conditions.
