Aug 29, 2022

Salicylic acid is white crystalline powder, odorless, slightly bitter and then acrid. The melting point is 157-159℃, and it gradually changes color when exposed to light. Relative density 1.44. The boiling point is about 211°C/2.67kPa. Sublimation at 76°C. Rapid heating under normal pressure decomposes into phenol and carbon dioxide. 1g of salicylic acid can be dissolved in 460ml of water, 15ml of boiling water, 2.7ml of ethanol, 3ml of acetone, 3ml of ether, 42ml of chloroform, 135ml of benzene, 52ml of turpentine, about 60ml of glycerol and 80ml of petroleum ether. It is derived from the alcohol exchange reaction between methyl salicylate and phenethyl alcohol under the action of sodium ethoxide. Used in a variety of flower-flavored daily chemical essences, and in trace amounts in edible essences such as peach, apricot, and molasses.

Features:
