Abstract

Aqueous solutions of difficulty soluble phenolic substances are prepared by dissolving them in presence of one or more water soluble salts of cinnamic acid. Evaporation of the solution to dryness yields a readily soluble preparation. The term phenolic substances includes phenols, cresols, substituted phenols such as thymol or chlor-phenol, or phenolic ethers, such as guaiacol. In examples employing sodium cinnamate (1) a solution containing 45 per cent phenol is produced, (2) 19 grams of o-cresol or 18 grams of m-cresol or 16 grams of guaiacol are dissolved in 100 ccs. of aqueous sodium cinnamate at room temperature, (3) 100 ccs. of 5 per cent sodium cinnamate dissolve 35 grams of p-chlorphenol and about 3 grams of vanillin. The solutions may be diluted to a large extent with water.ALSO:Aqueous solutions of difficultly soluble phenolic substances for pharmaceutical or disinfecting purposes are prepared by dissolving the substances in presence of one or more water soluble salts of cinnamic acid. Evaporated to dryness the solutions yield readily soluble phenolic preparations. Examples describe the preparation of solutions of phenol, o-cresol, m-cresol, guaiacol, p-chlorphenol and vanillin, using sodium cinnamate.
