Abstract
Aspen poplar wood meal has been subjected to catalytic hydrogenolysis in dioxane-water (9:1) at 500 psig initial pressure of hydrogen over a 5% rhodium-on-charcoal catalyst for five hours at 195 plus or minus 5 degrees C. The resulting chloroform-soluble lignin degradation products were separated by cellulose and silica gel column chromatography. The following compounds were isolated and identified: 4-hydroxybenzoic acid, 1-(4-hydroxy-3,4-dimethoxyphenyl)-1-propanone (propiosyringone), 2,2'-dihydroxy-3,3'-dimethoxy- 5,5'-dipropylbiphenyl, 2,3-bis(4-hydroxy-3,5- dimethoxyphenyl)-1-propanol, and a mixture of 3-(4-hydroxy-3,5-dimethoxyphenyl)-2(4-hydroxy- 3-methoxyphenyl)-1-propan and 3-(4-hydroxy-3- methoxyphenyl)-2-(4-hydroxy-3,5-dimethoxyphenyl)-1- propanol. 9 references.
