【Abstract】 Taking acrylic acid, n\|butyl alcohol as material,cation exchange resin as catalyst,the n\|butyl acrlate is synthesized.The condition of the kind and quantity of catalyst,the material mix ratio,the reaction time,the quantity retarder and the using times of catalyst is discussed.The experiment confirmed the kind of catalyst and the best technical condition.The result shows,731 strong acidity ion exchange resin is the best catalyze and high selection,it can be used serval times,esterify rate in 80.2%.The quality of production accord with country standard with satistactory results.The operation of technics is simple,the control of condition is easy,it hasn’t pollution.更多还原
