Usage: Acetophenone can be made by the reaction of benzene with acetyl chloride and acetic anhydride or acetic acid in the presence of alcl3. In addition, acetophenone is a by-product when ethylbenzene is catalyzed and oxidized to styrene. Acetophenone can have an addition reaction of carbonyl, a reaction of active hydrogen, and an electrophilic substitution reaction on the benzene ring, which mainly produces the interposition product. Acetophenone is used mainly as a raw material for pharmaceutical and other organic synthesis, and is also used in the preparation of spices. For making soap and cigarettes, it can also be used as a solvent for cellulose ether, cellulose ester and resin, as well as plastic plasticizer, which is hypnotic. When the solvent is used, it has high boiling point, stable, pleasant odor and so on. Solubility is similar to cyclohexanone, which can dissolve nitrocellulose, cellulose acetate, ethylene resin, coumarone resin, alkyd resin, glycerol alkyd resin and so on. It is often used in combination with ethanol, ketone, ester and other solvents. When used for spices, it is hawthorn; Mimosa; lilacs and other essential ingredients, and are widely used in soaping and tobacco essence.

Packaging, storage and transportation: 200KG/ drum, according to the general chemical goods transport. Shipment to complete the packing, loading should be safe. In the course of transportation, we should ensure that the container does not leak, does not collapse, does not fall, and does not damage. Non oxidizing agents, acids, edible chemicals mixed mixed transport. In transit, insolation, rain, and high temperature should be prevented. The vehicle should be thoroughly cleaned after the transportation of the vehicle.
