Description
Известный способ получени пирокатехина из газогенераторной смолы не нап1е,т практического применени .A known method of producing pyrocatechol from a gas generating resin is not practical, t.
Пред.;гагаетс способ получени пирокатехнновых концентратов из древееных смо;г, пригодный дл промышленного производства.Previously, a method for the production of pyrocatechnic concentrates from wooden resin, suitable for industrial production, is being developed.
Пирокатехиновые концентраты с содержаннем пирокатехина 70% и BHHje вл ютс ценными продуктами дл народного хоз йства, так как могут с.тужит1 дл различных композиций топлива. Из смолы, остави:ейс после извлече1п-1Я пирокатехина разгонкой, нолучаютс также цепные вещества: флотационное масло, антнокис.лители, крезол и другие.Pyrocatechol concentrates containing 70% pyrocatechol and BHHje are valuable products for the national economy, as they can be exhausted for various fuel compositions. From the resin, leave: it after the extraction of pyrocatechol by distillation, the chain substances are also obtained: flotation oil, anthelcite agents, cresol and others.
Суниюсть способа состоит в экстракции древесной смолы водой или.водой с метиловым спиртом при температуре 60-100°, т. е. в использовании высокой растворимости в воде пирокатехина, увеличивающейс в присутствии жпрных спиртов.The sunshine of the process consists in the extraction of wood resin with water or water with methyl alcohol at a temperature of 60-100 °, i.e., the use of high water solubility of pyrocatechin, increasing in the presence of surface alcohols.
В целом процесс получени пирокатехиновых концентратов из древесных смол сводитс к следующим онераци м:In general, the process of obtaining catechol concentrates from wood resins is reduced to the following operations:
I. Подогрев поступаюп ей смолы и растворител до температурыI. Preheating of resin and solvent to it
60-80 и фнльтрацн гор чей смолы .60-80 and fnltratsn hot resin.
2.Экстракци древесных смол при новыи1еппой температуре в противотоке одной водой и.ли водой с добавкой 10-20% жпрных спиртов.2. Extraction of wood resins at a new temperature in countercurrent with one water or with water with the addition of 10-20% of surface alcohols.
3.Охлажде1П1е водного экстракта и отделеипе от ув.гюченной смолы илн унарнвание водного экстракта под вакуу.мом до удалешш из )iero 75-80% воды.3. Cool the water extract and separate from the UV-treated resin or water extract under vacuum to remove 75-80% water from iero.
4.Экстракци пирокатехина пз водного экстракта серным эфиром, этилацетатом или его гомологами, смес дги сложных эфиров и т. п.4. Extraction of pyrocatechin pz of aqueous extract with sulfuric ether, ethyl acetate or its homologues, mixtures of esters, etc.
5.Отгонка раетворнтел из пирокатехина .5. Distillation of pyrotecatechol retarder.
6.Вакуум-разгонка ппрокатехипового остатка с отбором (фракций пирокатехина и его гомолов (110- 140 при 9 МЛ1 рт. ст.), жирных кислот и других продуктов.6. Vacuum-distillation of the catechip residue with the selection (fractions of pyrocatechol and its homols (110-140 at 9 ML1 Hg), fatty acids and other products.
7.Регенераци раетворител из нроэкс рагированиой воды.7. Recovery of the solvent from Nroex Extensions of water.
8.Переработка смол ного остатка на антнокислитель, флотационное масло и другие продукты.8. Processing of the pitch residue on the ant-oxidant, flotation oil and other products.
В результате обработки древесной смолы по указанной схеме извлекаетс 3-4% органических веществ , среди которых основным компонентом вл етс пирокатехин; содержанне пирокатехина в получсппом остатке составл ет около . Пр вакуум-разгонке этого остатка получаетс пирокатехнповый концентрат с содержанием пирокатехина 70%н . Выход такого концентрата составл ет около /о от безводной газогенераторной смолы .As a result of processing the wood resin according to this scheme, 3-4% of organic substances are extracted, among which the main component is pyrocatechin; the pyrocatechol content in the residue is about. By vacuum distillation of this residue, a pyrocatechol concentrate with a pyrocatechin content of 70% n is obtained. The yield of such a concentrate is about / o from the anhydrous gas generating resin.
