Present domestic ethyl butyrate manufacturer adopts traditional single pot of esterification technique intermittently mostly, this technology is summarized as follows: adopting butyric acid and ethanol is raw material, in the preparation process of industrial ethyl butyrate, generally adopting materials such as benzene to form ternary azeotrope with ethanol, water, thus except that the method for anhydrating comparatively common; In the preparation process of edible ethyl butyrate, for pure property and the edible security that keeps product, do not allow material such as benzene to participate in the technological process, so the production of edible ethyl butyrate generally adopts butyric acid and excess ethanol to carry out esterification, after esterification finishes, add in the liquid caustic soda and nonesterified butyric acid, make it to generate Sodium propanecarboxylate and layering, ethyl butyrate thick ester in upper strata is after washing, rectifying, get the ethyl butyrate finished product, lower floor's Sodium propanecarboxylate solution adds the vitriol oil and carries out acidifying, dehydration after reclaiming ethanol, concentrating, thus the recovery part butyric acid.The subject matter that this traditional technology exists is; The butyric acid productive rate only is 7380%, the raw material consumption height, the production cycle is long, equipment capacity is low, facility investment is big, wastewater discharge is big etc. Whole go out finished product during, vapor pressure 0.150.20MPa (gauge pressure) in the serious reciprocal of duty cycle 0.07330.0753MPa of control tower, 8285 of tower top temperatures, 9295 of tower still feed temperatures, the chuck.In early stage that goes out finished product and mid-term, the control reflux rate is 90100 liters/hour, to go out finished product speed be 150160 liters/hour; In the later stage that goes out finished product, reflux rate is reduced to 5030 liters/hour gradually, goes out that finished product speed is also corresponding reduces to 5030 liters/hour; When going out finished product speed and reduce to about 20 liters/hour, fragrance is commented in sampling at any time, changes slightly as fragrance, promptly finishes finished product.
