Improvement in the process for the production of salicylate of sodium by reaction of sodium phenolate and carbon dioxide

摘要

An improved process for the production of sodium salicylate and salicylic acid from phenol at a high degree of conversion with a concomitant reduction in undesirable by-products. The process comprises reacting a sodium phenolate with carbon dioxide in a direct, single step at a temperature above about 165 DEG C. to produce directly sodium salicylate, which is then converted by conventional means to the salicylic acid.
