Process for producing esters |
| abstract |
A process for producing esters comprises esterifying an acid or anhydride with an excess of an alcohol to produce a crude ester, recovering excess alcohol from the crude ester and recycling recovered excess alcohol to the esterification reaction together with fresh alcohol. The process is improved by controlling the ratio of the amount of recycled alcohol and the amount of fresh alcohol in dependence on the level of impurities in the recycle alcohol. Further improvements come from feed forwarding fresh alcohol analysis results and from preheating the alcohol before loading into the reactor. Preferably, ester product quality is improved by stripping the alcohol for oxygen removal prior to esterification. |
