| Zusammenfassung: | Preparation of esters of maleic acid with monohydric alcohol by forming maleic anhydride by oxidizing a hydrocarbon in a maleic anhydride reaction, scrubbing the gaseous effluent to form aqueous maleic solution which is reacted and dehydrated in a first stage with monohydric alcohol in a distillation column. Reacting the product of the first stage under pressure and under conditions such that boiling occurs. |
