Abstract

The paper describes the pyrolytic transformation of hydrolysis lignin in 1,4-dioxane at a temperature of 250°C and a pressure of 13.0 MPa and the subsequent Ru/C-catalyzed hydrogenation of the products at a temperature of 250°C and a pressure of 10.0 MPa in an autoclave. It has been found that the thermal pyrolysis of hydrolysis lignin with 1,4-dioxane and the catalytic hydrogenation of pyrolysis products are accompanied by C−O and C−C bond cleavage and formation of a products mixture consisting of soluble oligomer and monomer phenol derivatives, products of their hydrogenolysis and hydrogenation, and also mixtures of C1−C5 gas hydrocarbons and C2−C5 alcohols, and ethers formed mainly during the destruction of the solvent (1,4-dioxane) under the reaction conditions.

水解木质素在1,4-二氧六烷中的热非均相催化转化
本文描述了水解木质素在1,4-二氧六烷中在250℃、13.0 MPa压力下的热解转化,以及随后在250℃、10.0 MPa压力下Ru/C催化产物在高压釜中的加氢反应。研究发现,木质素与1,4-二氧六环的热裂解和热解产物的催化加氢伴随着C−O和C−C键的裂解,形成了由可溶性低聚物和单体苯酚衍生物及其氢解和加氢产物组成的混合物,以及C1−C5气态烃和C2−C5醇的混合物。在反应条件下,溶剂(1,4-二恶烷)的破坏过程中主要形成醚。

期刊介绍: Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
