glycol late

[Eng. glycoll ( ic ); -ate.] Chem.: A salt of glycollic acid (q. v.). gly-col-lic, a. [Eng., ., glycol , I connective, -ic.] Derived from or pertaining to glycol (q. v.). glycollic-acid, s. Chem.: Oxyacetic acid, oxacetic acid, C2H4O3, or A diatomic monobasic fatty acid, con CH2OH соон. taining an alcohol and an acid radical. It occurs in sour grapes and in the leaves of Ampelopsis he deracea. Glycollic acid can be obtained by the oxidation of glycol, by the action of nitric acid on alcohol, by heating a solution of oxalic acid to 100° for week with granulated zinc, the oxalic acid being reduced by the nascent hydrogen, but it is best obtained by boiling in a flask connected with a condenser a mixture of one part of chloracetic acid, CH2Cl-COOH, with twenty-four parts of water, some hours; the product is evaporated water bath. Glycollic acid crystallizes out of water in needles, which melt at 80°. It is soluble in alcohol and in ether; by the action of concent rat ed nitric acid it is oxidized into oxalic acid, COOH. Glycollic acid forms crystalline salts called COOH. glycollates. glycollic-anhydride, s. CH2-COOH Chem.: C4H6O5, or O
