Abstract

Process for the production of alkaline salts of terephthalic acid by thermal isomerization, in the presence or absence of alkaline salts catalysts of benzene carbonic acids with or without pressure in a heatable, multi-axis screw apparatus, characterized in that the isomerization is carried out in a screw device with two or more screws of the same gear that mesh very closely together.
