| titleOfInvention | A kind of production method of n-propyl acetate |
| abstract | The present invention relates to a kind of production method of n-propyl acetate is it is characterised in that described step is：Acetic acid and propanol preheated rear entrance react generation n-propyl acetate in esterification column, obtain thick n-propyl acetate through condensing；Send into treating column after thick n-propyl acetate preheating and n-propyl acetate finished product is obtained in bottom of towe；Treating column top gaseous phase thing is sent in scalp pomade tank after partial condensation, includes liquid and gas in scalp pomade tank simultaneously：Scalp pomade tank internal upper part is low boiling gaseous component, controls scalp pomade pressure tank, and then by pipeline, low boiling gaseous component is passed directly into the continuation participation reaction of esterification column bottom.Provide part of heat energy for reaction, the yield of product can be effectively improved, reduce the energy being lost because low boiling point component circulates in refining system for a long time；Meanwhile, by controlling the pressure of scalp pomade tank, the heating for esterification that treating column gas phase is stable can be made, increased the stable of system and operability. |
