Batch esterification |
| abstract |
To reduce batch cycle time in a process for producing a plasticizer ester for polyvinyl chloride (PVC) using a catalyst from a reactant comprising an acid or anhydride and a C4 to C15 monohydric alcohol Provide a method. A process comprising the following batch reaction procedure: (i) supplying an alcohol to a mixture of acids or anhydrides at an initial temperature in a reaction vessel; and (ii) performing the esterification at a temperature of the mixture. And (iii) removing by-product water produced in the esterification reaction by boiling, in which case as the temperature of the mixture is increased at least in the initial stages of increasing the temperature of the mixture, A pre-determined increase in pressure in the reaction vessel, thereby reducing the evaporation of the reactants, and the esterification catalyst is below the desired esterification reaction temperature and above the initial temperature of the mixture It is introduced into the mixture at the temperature of the mixture.
