Abstract

본 고안은 목재를 화학처리하지 않고 직접 용액화하는 방법에 관한 것이다.The present invention relates to a method of directly liquefying wood without chemical treatment.

종래 목재의 용액화방법은 목재칩 또는 목분을 아세칠화, 메칠화 등의 화학처리를 하고 이 화학처리된 목재를 다시 용액화하는 2단계방법으로 하는 것이었기 때문에 용액화공정이 간단하지 못하고 용액화율도 낮은 문제가 있는 것이다.The conventional method of liquefaction of wood is that the wood chip or wood powder is chemically treated, such as acetylation, methylation, etc., and a two-step method of liquefying the chemically treated wood. There is also a low problem.

또 목재를 화학처리하지 않고 직접 용액화하는 방법으로서 유기용제를 사용하여 250℃ 이상의 온도로 30-150분간 처리하는 방법이 알려져 있으나 아직 연구단계로서 그 구체적 방법은 제시되지 않고 있다.In addition, as a method of directly liquefying wood without chemical treatment, a method of treating 30-150 minutes at a temperature of 250 ° C. or more using an organic solvent is known, but a specific method has not yet been proposed as a research step.

본 발명은 화학처리하지 않은 목재칩 또는 목분(木粉)을 크레졸과 각종산의 수용액을 혼합한 혼합용액과 함께 밀폐용기에 넣고 200℃ 이하의 온도로 가열증해하므로서 용액화율이 높으면서 간단하게 목재가 용액화되도록한 것이다.In the present invention, the wood chips or wood flour without chemical treatment are put together in a sealed container with a mixed solution of cresol and aqueous solution of various acids. Is to be liquefied.
