Product Applications

The divinylbenzene obtained by diethyl benzene dehydration is a cross-linking agent of polystyrene resin, and is also used as an intermediate of ion exchange resin and other organic synthesis, and can also be used as a solvent. P-diethylbenzene is the reverse instant medicines to be mixed with water before administration of Polyester Raw material refined p-xylene adsorption bed.

Production method

In industry, diethylbenzene is a by-product of ethylbenzene production. At present, a large amount of ethylbenzene is prepared by alkylating benzene with ethylene, and a small amount of ethylbenzene is separated from mixed xylene fraction. Industrial diethylbenzene, in which the adjacent position is about 9.4, the intermediate position is 61.5, and the para position is 29.1.
