| abstract | PURPOSE: To produce the subject compound useful as a raw material for preservative, mildew-proofing agent, pharmaceuticals, dyes, etc., without forming by-products, at a low cost, by reacting an alkali metal salt of phenol with carbon dioxide using a specific monocyclic aromatic hydrocarbon as a solvent. n CONSTITUTION: The objective compound is produced by reacting an alkali metal salt of phenol with carbon dioxide in the presence of phenol using a monocyclic aromatic hydrocarbon as a solvent at 170-300°C. The amount of phenol is 0.05-10mol, preferably 0.1-5mol and that of carbon dioxide is 0.1-100mol, preferably 0.5-50mol based on 1mol of the phenol alkali metal salt. The above solvent is a monocyclic aromatic hydrocarbon expressed by formula (R is lower alkyl; n is 1-4; when n≥2, R groups may be same or different), e.g. 1,2,3-trimethylbenzene. n COPYRIGHT: (C)1989,JPO&Japio |
