Method for Separating Methanol from the reaction product obtained in a reactor in the C4 to C7 isoolefinas Esterification with methanol.

摘要

Method for Separating Methanol from the reaction product obtained in a reactor in the Esterification isoolefinas C C 4 to 7 with methanol.The alcohol extraction with water, methanol / water extracts in a ratio of 1: 15 to 1: 10 temperature of 20 c to 60 C; then the aqueous extract obtained is distilled to separate the serving of Alcohol and Methanol to remove the top of the distillation column and the Tertiary alcohols are removed as a Retrograde flow from a plate with A high concentration of the same, recirculandolos a scrubbing column.
