| titleOfInvention | Method of obtaining polyquinones |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to method of obtaining polyquinone by oxidative dehydration of initial monomer: hydroquinone, and/or benzoquinone, and/or quinhydrone, and/or pyrocatechol, and/or their mixtures in presence of mild dehydrating agent, spatially substituted diphenoquinone of general formula (1) with obtaining final product: polyquinone and equimolar quantity of spatially substituted bisphenol of general formula (2). Reaction can take place in presence of water in neutral medium, and/or acidic medium, and/or alkaline medium in mixture with hydrocarbon solvent, in which dehydrating agent and initial monomer are dissolved, in interval of temperatures from 50 to 200°C and reaction duration not more than 3 hours. Claimed method makes it possible to obtain polyquinone with output to 95% with conversion on initial spatially substituted diphenoquinone to 100%. (1), (2). In formulae (1) and (2) R1-4 stand for alkyl radical, and/or halogen, and/or cyano group. n EFFECT: increase of output. n 3 cl, 1 tbl, 13 ex |
