The conditions of the reaction were as fonows : The reaction times were 3,6,12 hrs. respectively, the alkali concentrations were 5, 10, 15, 20 and 25 Wt. %, and the mol. ratio of ethalnol : sodium hydroxide was 2.4:1. By the hydrogenolysis at the reaction temp. 200℃ and 250℃, humic acid (molecular weight about 2400) was converted into low molecular humic acid (mol. wt. 500?700), and mol. number of the absorbed H_2 by 100 g humic acid was 2.4?2.6,in this case,though the effect of alkali concentration was not conformed. And thus two fractions of the ethanol-soluble humic acid arid the ethanol-insoluble humic acid were obtained, as a result of the above reaction ; the yield of the ethanol-soluble humic acid was about 60?90%. At the reaction temp. 350℃, humic acid was converted into the tar and the hydrogenated oi1.}, pages = {29--37}, title = {泥炭フミン酸に.関する研究(4)泥炭フミン酸のエタノールかせいソーダ法による水添分解に関する考察}, volume = {1}, year = {1965} }
