Description

За влено 16 апрел  1948 г. за .Yg 377468 в Комитет по изобретени м и открыти м при Совете Л инистров СССРIt was filed on April 16, 1948 for. Yg 377468 to the Committee on Inventions and Discoveries at the Council of Ministers of the USSR

Древесину в виде кружков толщиной около 100 мм подвергают пирогенетической обработке в среде керосина при 275° и- нормальном давлении. При этом в интервале температур 100-220° вместе с керосином отгон етс  влага, а при 220-275° отгон етс  концентрированный погон лесохимикатов. Остатки керосина удал ют из древесины путем продувки ее вод ным паром (лучше перегретым до 150-200°).Wood in the form of circles with a thickness of about 100 mm is subjected to pyrogenetic treatment in kerosene at 275 ° and normal pressure. At the same time, moisture is distilled off along with kerosene in the temperature range of 100–220 ° C, and at 220–275 ° C, concentrated condensate of chemical chemicals is distilled. Kerosene residues are removed from the wood by blowing it out with water vapor (preferably overheated to 150-200 °).

Полученную бурую древесину измельчают в щепу и подвергают экстракционной обработке ацетоном или спиртом. После отгонки экстракта до концентрации 30-40% получаетс  лак темно-красного цвета. Выход сухой смолы составл ет около 5% от веса исходной сухой древесины . Из 1 кг исходной сухой древесины можно получить до 15-17% (по весу) спиртового лака с 35%-ной концентрацией смолы (в среднем).The obtained brown wood is crushed into chips and subjected to extraction treatment with acetone or alcohol. After distilling off the extract to a concentration of 30-40%, a dark red lacquer is obtained. The dry resin yield is about 5% by weight of the original dry wood. From 1 kg of the original dry wood, you can get up to 15-17% (by weight) of alcohol varnish with a 35% resin concentration (on average).

Предмет изобретени Subject invention

1.Способ получени  смолы из древесины, подвергнутой пирогенетической обработке в среде нефтедестиллатов при температуре до 275°. отличающийс  тем, что обработанную древесину после пропаривани  дл  удалени  остатков нефтедестиллатов измельчают и обрабатывают пол рными органическими растворител ми, в частности, спиртом ИЛИ; ацетоном, с последующей отгонкой растворителей из экстракта.1. A method of obtaining resin from wood subjected to pyrogenic treatment in the environment of petroleum distillates at temperatures up to 275 °. characterized in that the treated wood after steaming is crushed and treated with polar organic solvents, in particular, OR alcohol, to remove residues of petroleum distillates; acetone, followed by distillation of the solvent from the extract.

2.Применение смолы, полученной согласно п. 1, в качестве пленкообразующего .2. The use of the resin obtained according to p. 1, as a film-forming.
