uses | salicylic acid esters have many varieties of spices, of which the most commonly used are methyl salicylate, isoamyl salicylate, benzyl salicylate. The content of methyl salicylate in birch bark oil is up to 96%, in addition in essential oils such as cinnamon oil, ylang oil, violet oil, tuberose oil and so on, however, the inclusion of other salicylates in essential oils has not been reported. Isoamyl salicylate is the most important species of amyl ester, which is the main agent for blending Clover essence. In the preparation of Carnation flavor, it is used as a multi-tone agent and fixative. It can be well blended with oak moss extract, perilla oil, geraniol, etc. This product is a raw material for organic synthesis. Also used as soap flavor and solvent. |
production method | prepared by reaction of salicylic acid in the presence of sulfuric acid. In the presence of sulfuric acid, salicylic acid dissolved in isoamyl alcohol is reacted by heating, the isoamyl alcohol formed from the reaction and remaining is distilled off, and the isoamyl alcohol after removal of water is returned to the reaction. After completion of the reaction, the resulting product was washed with water and sodium carbonate solution to remove salicylic acid. An aqueous solution of salicylate is acidified to precipitate salicylic acid, which can be reused in the reaction. The crude isoamyl salicylate was subjected to vacuum distillation. In order to improve the flavor quality, impurities may be removed by steam evaporation in advance. The yield of isoamyl salicylate was 80%. |
