PROCESS FOR PREPARING 3-PICOLINE

摘要

Process for the production of 3-picoline. Acrolein or a mixture of acrolein and formaldehyde is reacted in a liquid aqueous phase at a temperature of 180 DEG to 280 DEG C. in a closed vessel. Ammonia and/or ammonium ions, and anions of an inorganic or organic acid, which has an acid dissociation constant of 106 to 10-12, at 20 DEG C., are also present.
