摘要：
An investigation of the derivatives of water-soluble acids from an ethanol-benzene extract of weathered brown coal with o-phenylene-diamine has shown that the mean molecular weight of the acids investigated is about 300 and that not less than half these acids have the atomic grouping of an alpha -keto acid in their structure.
