FIELD: chemical industry; new method of production of 2,4,4,6-tetrabromine-2,5-cyclohexadienon. ^ SUBSTANCE: the invention is pertaining to the new method of production of 2,4,4,6-tetrabromine-2,5-cyclohexadienon, which one has the wide application as the semi-finished product in chemistry of organic synthesis, for example at production of the linear poly(phenylene oxides). The method consists in production of 2,4,4,6-tetrabromine-2,5-cyclohexadienon in one container and provides for interaction of phenol with the brominating substance consisting of the mixture of the alkaline metal /alkaline earth metal bromide and the alkaline metal /alkaline earth metal bromate soluted in the deionized water at presence of the acid, extraction, washing and drying of the deposit with production of 2,4,4,6-tetrabromine-2,5-cyclohexadienon. The technical result of the invention is simplification of the production process due to usage of phenol as the original substance and the combination of the alkaline metal /alkaline earth metal bromides and the alkaline metal /alkaline earth metal bromates. ^ EFFECT: the invention ensures simplification of the production process due to usage of phenol as the original substance and the combination of the alkaline metal /alkaline earth metal bromides and the alkaline metal /alkaline earth metal bromates. ^ 15 cl, 4 ex |
