Hot dilute mineral aci ls convert it into a brown substance, ulmic acid, and, in the presence of air, formic acid. It dissolves in concentrated H SO, without coloration, forming sulphoglucic acid. Cold concentrated HNOy converts it into nUro-glucoee hot dilute HNO, oxidizes it to a mixture of oxalic aud oxysaocharic acids. With organic acids it forms ethers. Its solutions dissolve potash, soda, lime, bf ta, and the oxides... [Pg.185]
