Abstract
1277376 Dicarboxylic esters CHEMIEFASERKOMBINAT SCHWARZA WILHELM-PIECK VEB 2 Feb 1970 4873/70 Heading C2C In a process for the continuous esterification of dicarboxylic acids with alcohols, especially of terephthalic acid with ethylene glycol, a ground dicarboxylic acid is intensively mixed with a vaporized alcohol, the alcohol condensing on the surface of the dicarboxylic acid particles and providing the necessary reaction temperature of 240-320‹ C. whereafter the liquid-enveloped dicarboxylic acid particles are deposited on heating surfaces and the dissolving and esterification is carried out in a reaction chamber, provided with heated inserts, in the presence of excess alcohol vapour and/or of an inert gas, heated to the reaction temperature as flushing agent from the water formed by the reaction. In the example, using the device in the figure, ethylene glycol passes through vaporizer 2 and pipe 3 to mixing nozzle 4 where it is mixed with ethylene glycol from preheater 20 and ground terephthalic acid introduced through charging valve 5. The liquid enveloped terephthalic acid particles flow through heated chamber 11 and are further heated by inserts 8b and the esterified product is removed from sump 12 by pump 19. Heated nitrogen passes into sump 12 and acts as flushing agent.
