The consumption of raw materials fixed : 1600kg benzyl chloride, t; Soda 1000, t.
purposes : benzyl alcohol is very useful for determining incense, jasmine; On the next incense; Yilanyilan Flavorings such as when an indispensable spices. For the preparation of soap; Daily makeup 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. For paint solvents; Photo reagent; PVC stabilizer; Medicine; Synthetic resin solvent; Vitamin B injection of solvent; Solution ointment or preservatives. Used nylon yarn; Fibers and plastic film desiccant dye; Cellulose acetate; Casein protein solvent, preparation benzyl ester or ether intermediates. Meanwhile, widely used in nib (pen oil); Paint solvent.
