nature Description : gentle liquid. The boiling point of 320 ° C and 208 ° C (3.33kPa), 170 ° C (0.67kPa), the relative density of 1.1799 (20 / 4 ° C), the refractive index 1.5805. With ethanol; Compatibility ether slightly soluble in water. Weak with sweet fragrance.
production methods : by acid reaction with benzyl alcohol derived. May also sodium salicylate and benzyl chloride derived reaction. The sodium salicylate and slightly excessive amount of benzyl chloride mixture, by adding a small amount of diethylamine, heated to 130-140 ° C17 (h), cooling water after washing reaction, excessive use of benzyl chloride steam distillation to remove the remaining oil to the bar for vacuum distillation, collecting 170-175 ° C ( 0.93kPa) fractions. The yield of 85%.
purposes : as spices, especially nitro musk solvents, artificial musk perfume and the scent of incense fixed dose. Biocide.
