CAS, DSC-51-6
nature : colorless and transparent liquid. Slightly fragrant smell. Combustible. -15.4 ° C melting point, boiling point, 205.4 ° C and 189 ° C (66.67kPa), 141 ° C (13.33kPa), 93 ° C (1.33kPa.Conclusion), the relative density of 1.0419 (24 / 4 ° C), the refractive index 1.53955, the flash point of 100.4 ° C and 436 ° C spontaneous combustion point. Slightly soluble in water (1 methanol soluble in benzene 40 parts water), with alcohol, ether, chloroform and other segments. Advances in the presence of natural scent oils, Yilanyilan oil, sesame oil on substances such as under, free state or ester form.
Preparation Methods : benzyl chloride as raw materials, base-catalyzed hydrolysis of heating derived. Spices benzyl alcohol level specifications (QB792-81) : 1.041-1.046 relative density, refractive index 1.538-1.541, 203-206 ° C-boiling distillation capacity is more than 95%, the solubility of insoluble all 30 times the capacity of distilled water, containing Alcohol �98% chlorine test (N.F) for the reaction. The consumption of raw materials fixed : benzyl chloride 1600kg / t, 1000 Soda / t.
purposes : benzyl alcohol is very useful for determining incense, jasmine, on the next fragrance, flavor, etc. Yilanyilan deployment indispensable spices. For the preparation of soap, and daily make-up flavor. But Benzyl Alcohol can slow the natural oxidation, part of formaldehyde and benzene formation benzyl ether, often with products sold almond aromas, it is not appropriate to long storage. Benzyl alcohol in industrial chemicals production a wide range of uses. Solvents used in the coatings, photo developer, PVC stabilizer, medicine, synthetic resin solvent, vitamin B injection of solvent, creams or liquids preservatives. Used nylon yarn, fiber and plastic film desiccant, dyes, cellulose esters, casein protein solvent, preparation benzyl ester or ether intermediates. Meanwhile, widely used in nib (pen oil), paint solvent.
