Description
СПОСОБ ПОЛУЧЕНИЯ МНОГОАТОМНЫХ ФЕНОЛОВMETHOD OF OBTAINING MULTIHEADABLE PHENOLS
Изобретение относитс к области получени многоатомных фенолов, вл ющихс ценным сырьем дл химической промышленности. This invention relates to the field of producing polyatomic phenols, which are valuable raw materials for the chemical industry.
Известен способ получени многоатомных фбноло в, состо щий в том, что древесную смолу подвергают парофазному пиролизу при 450-600°С С последующей фракционной разгонкой лолученного пиролизата.A known method for producing polyatomic fbnolo in consists in that the wood resin is subjected to vapor phase pyrolysis at 450-600 ° C With the subsequent fractional distillation of the obtained pyrolysate.
Выход пиролизата 57%.The output of pyrolysate 57%.
Дл уокорепи процесса и увеличени выхода целевого продукта предлагаетс процесс вести в присутствии катализатора - аммиака.In order to increase the yield of the target product, the process is proposed to be carried out in the presence of an ammonia catalyst.
Пример. Пиролиз газогенераторной смолы .провод т в терМОконтактном аппарате с твердым теплоносителем при 350-550°С. Одповременно со смолой в аппарат ввод тExample. The pyrolysis of the gas-generating resin is carried out in a thermal-contact apparatus with a solid heat carrier at 350-550 ° C. Along with the resin is introduced into the apparatus
аммиак 10%-ной концентрации. Деметилирование эфиров фенолов смолы протекает в паровой фазе. Полученный пиролизат подвергают фракционной нерегонке.ammonia 10% concentration. Demethylation of phenol resin esters occurs in the vapor phase. The resulting pyrolysate is subjected to fractional non-distillation.
Предмет изобретени Subject invention
Способ получени многоатомных фенолов путем парофазного пиролиза древесной смоjibi при повышенной температуре.с носледуюи;ей фракционной разгонкой полученного пиролизата , отличающийс тем, что, с целью увеличени выхода пиролизата и сокращени продолжительности процесса, последний ведут в присутствии аммиака в качестве катализатора .The method of producing polyatomic phenols by vapor-phase pyrolysis of wood smibi at elevated temperature is followed by fractional distillation of the resulting pyrolysate, characterized in that, in order to increase the yield of pyrolysate and reduce the duration of the process, the latter is carried out in the presence of ammonia as a catalyst.
