Description
Описываемый способ очистки бензольной головки от ненасыщенных соединений в отличие от известных способов нозвол ет выделить нолимерные соединени и использовать их в производстве лаков, клеев и пластических масс. Дл этого свежую обезвоженную бензольную головку обрабатывают комплексом фтористого бора с органическими соединени ми , например диэтиловым эфиром, метиловым и этиловым спиртами , уксусной КИСЛОТОЙ, СЛОЖНЫМИ эфирами.The described method of cleaning the benzene head from unsaturated compounds, in contrast to the known methods, makes it possible to isolate polymer compounds and use them in the production of varnishes, adhesives and plastics. To do this, fresh dehydrated benzene head is treated with a complex of boron fluoride with organic compounds, for example diethyl ether, methyl and ethyl alcohols, acetic acid, COMPLEX ethers.
Процесс очистки осуществл етс при небольшом (0,3-0,4% от сырь ) расходе катализатора (комплекса фтористого бора), который может быть сравнительно легко регенерирован.The cleaning process is carried out with a small (0.3-0.4% of the raw material) consumption of the catalyst (boron fluoride complex), which can be relatively easily regenerated.
Пример. В реактор, снабженный мещалкой, обратным холодильником и вод ной рубашкой, заливают бензольную головку и при ненрерывно работающей мепталке добавл ют раствор катализатора в ароматических углеводородах (бензоле, ксилоле, сольвенте и др.) из расчета 0,3-0,4% от веса бензольной головки (счита на фтористый бор). Врем реакции 30-40 мин. Далее реакционную массу, с целью ее нейтрализации и регенерации катализатора, обрабатывают сухим аммиаком, после чего подвергают фильтрации дл отделени вьшавщего осадка аммиаката фтористого бора. Путем обработки аммиаката фтористого бора серной КИСЛОТОЙ снова получают фтористый бор. Из фильтрата отгон ют сероуглерод и бензол. Остаток представл ет собою раствор смолы желтого цвета в углеводородах. Выход полимерных соединений около 20-30% зависит от содержани ненредельных углеводородов в составе,Example. The benzene head is poured into the reactor, equipped with a broom, a reflux condenser and a water jacket, and with a continuously operating meptalka, a solution of the catalyst in aromatic hydrocarbons (benzene, xylene, solvent, etc.) is added at a rate of 0.3-0.4% by weight benzene head (counting on fluoride boron). The reaction time is 30-40 minutes. Next, the reaction mass, in order to neutralize it and regenerate the catalyst, is treated with dry ammonia, after which it is subjected to filtration in order to separate the total precipitate of ammonium fluoride boron. By treating boric ammonium fluoride with sulfuric acid, boron fluoride is again obtained. Carbon disulfide and benzene are distilled off from the filtrate. The residue is a solution of a yellow resin in hydrocarbons. The yield of polymeric compounds of about 20-30% depends on the content of non-specific hydrocarbons in the composition,
