Title: 2-Hydroxy-3-naphthoic acid by carboxylation of beta naphtholate - using high shear agitation in the presence of beta naphthol
Inventor: BACHMANN WILFRIED DIPL ING DR
IPC: C07C51/15
Filed: 1975-05-17
Abstract: 2-Hydroxy-3-naphthoic acid (I) is prepared by reacting carbon dioxide on alkali metal salts of beta-naphthol in the presence of beta-naphthol at high temp. and pressure and the reaction is carried out being subjected to a continuous shearing action in time and space.
