English title : dimethyl-benzene; Xylene; Dimethylbenzene; AI3 - 02209-x; dimethyl-benzen; caswell no 906; accessible pesticide chemical code 086802; ksylen

nature Description : right-xylene; o 2 toluene; among ethylbenzene and xylene mixtures. The relative density of about 0.86, 27.2-46.1 ° C flashpoint. For transparent colorless liquid. Soluble ethanol and ether, do not dissolve in water.

production methods : 1. Coking-product recovery of benzene-product coking high temperature hot tar, the part containing benzene. By the beginning of the first distillation tower early run, a light tower benzene, benzene bottom heavy (benzene for Preparation Coumarone resin raw materials). Benzene first light by early distillation tower, the bottom mixed fractions by acid washing to remove impurities, and then blowing into benzene tower steam blowing, and then in pure benzene distillation column distillation.

2. Platinum restructuring atmospheric distillation method using the light gasoline (initial boiling point of about 138 ° C) and interception fraction greater than 65 ° C, the first by molybdenum catalyst, catalytic hydrogenation emerge harmful impurities, and then platinum catalyst to revitalize, use two glycol ether solvent extraction, and then by distillation tower again, to be benzene; toluene; xylene and other products.

purposes : it is mixed xylene neighbors; Among; Right ethylbenzene and xylene mixtures. As the use of chemical raw materials, can be pre-isomer separation. The mixture is mainly used for the coating of paint solvents and aviation fuel additives.
