| abstract | PROBLEM TO BE SOLVED: To provide an object of the present invention, wherein 2-methyl- with low odor It is to provide 2,4-pentanediol and a method for producing the same. SOLUTION: The present invention provides the following [1] to [4]. [1] 2-Methyl-2,4-pentanediol having an absorbance of 0.1 or less at a measurement wavelength of 220 nm when an optical path length of a sample is 1.0 cm in an analysis by a spectrophotometer. [2] Crude 2-methyl-2,4-pentanediol is mixed with water and an organic solvent to separate phases into an aqueous layer and an organic layer, and then the aqueous layer containing 2-methyl-2,4-pentanediol is separated. A method for producing 2-methyl-2,4-pentanediol comprising a step of obtaining. [3] The method for producing 2-methyl-2,4-pentanediol according to [2], wherein the organic solvent is an aliphatic hydrocarbon. [4] The method for producing 2-methyl-2,4-pentanediol according to [2] or [3], comprising a step of subjecting an aqueous layer containing 2-methyl-2,4-pentanediol to distillation. |
