Claim Text:
1. A process for the purification of an alcohol comprising: (1) providing a reaction zone (C) comprising an acid type catalyst; (2) providing a reaction zone (B) comprising an adsorbent material and/or a combination of sorbent materials; (3) providing an alcohol stream comprising impurities, wherein the impurities comprise nitriles, carboxylic acids, amides and the corresponding thio-compounds, or imines; (4) introducing the alcohol stream of (3) into the reaction zone (B) and bringing said alcohol stream into contact with the adsorbent material and/or combination of sorbent materials at conditions effective to reduce the amount of impurities having an adverse effect on the acid type catalyst of the reaction zone (C); (5) recovering from step (4) an alcohol stream and introducing it into the reaction zone (C); (6) introducing one or more reactants (R) into the reaction zone (C); (7) operating said reaction zone (C) at conditions effective to recover a valuable effluent, wherein the reaction zone (C) provides the dehydration of the alcohol.
