Properties and stability

Stable at room temperature and pressure, avoid contact with oxides.

Storage method

1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging is sealed. should be kept away from oxidizer, do not store together.

2. Equip with corresponding varieties and quantities of fire-fighting equipment. Suitable materials should be available in the storage area to contain spills.

Synthesis method

1. Obtained from the reaction of salicylic acid and benzyl alcohol.

2. It can be obtained by the reaction of sodium salicylate and benzyl chloride. Add a small amount of diethylamine to the mixture of sodium salicylate and a slight excess of benzyl chloride, heat to 130-140°C and react for 17 hours. After cooling, wash the reactant with water. Excess benzyl chloride is removed by steam distillation, and the remaining The oil is vacuum distilled and the 170-175°C (0.93kPa) fraction is collected. Yield 85%.

2. From salicylic acid and Derived from esterification of phenylethyl alcohol.

Purpose

1. Mainly used for preparing apricot, peach, banana, raspberry and other flavors. It can also be used as a bactericidal preservative. A good solvent for the synthesis of nitromusk. It is a good fixative for floral scents such as clove, carnation, lily of the valley, and jasmine. It is also used in small amounts in food flavors to prepare raisin and red currant flavors. Product quality: content ≥98%.

2.Used as ultraviolet absorber, spice, fixative and bactericidal preservative.

3. Used for the preparation of spices, suitable for the preparation of solvents for artificial nitro musk and fixatives for floral fragrances.
