Title of Invention | HIGHLY-PURIFIED1,3-BUTYLENE GLYCOL |
---|---|
Abstract | High purity 1,3-butylene glycol obtained from acetaldol by a liquid phase hydrogen reduction method, by adding a base to crude 1,3-butylene glycol free of high-boiling material, heat treating the mixture and then distilling off 1,3-butylene glycol. In high performance liquid chromatography analysis under specified condition, each peak eluted in a relative time of 1,3-butylene as 1.0, has an absorbance of 0.02 or less at a measuring wavelength of 210 nm. This has no odor and shows less change with time. |
