    Abstract: An alcohol production method whereby high quality alcohol can be easily and effectively produced includes a step in which an alcohol solution, which contains sugar and/or sugar alcohol as an impurity and an alcohol other than sugar alcohol as a main component, has the sugar and/or sugar alcohol adsorptively removed therefrom by contacting the alcohol solution with one type or a mixture of two or more types of adsorbents selected from zeolite, an ion-exchange resin, silica alumina, and alumina.

    Abstract: A diol composition comprising 95% by weight or more of a diol selected from the group consisting of ethylene glycol, 1,2-propanediol, 1,3-propanediol, 1,3-butanediol, 1,4-butanediol, 2,3-butanediol, 1,5-pentanediol, 1,2-pentanediol, 1,3-pentanediol, 1,4-pentanediol, neopentyl glycol, 1,6-hexanediol, 1,7-heptanediol, 1,8-octanediol, 1,9-nonanediol, 1,10-decanediol, diethylene glycol, polyethylene glycol, polypropylene glycol, polytetramethylene glycol, 2-methyl 1,3-propanediol, 3-methyl-1,5-pentanediol, 2-methyl-1,8-octanediol, 2,2-diethyl-1,3-propanediol, 1,2-cyclohexanediol, 1,4-cyclohexanediol, 1,2-cyclohexanedimethanol, 1,4-cyclohexanedimethanol, 1,3-cyclobutanediol, 2,2,4,4,-tetramethyl-1,3-cyclobutanediol, hydrogenated bisphenol A, isosorbide, isomannide, isoidide, hydroquinone, resorcin, dihydroxybiphenyl, naphthalene diol, dihydroxybenzene, and dihydroxytoluene and impurities in an amount sufficient to cause the diol composition to have an electrical conductivity of 0.6 to 30 mS/m. The diol composition may be used in the production of a polyester material having a reduced thermal weight loss rate and improved mechanical properties and molding stability.

    Abstract: Lactic acid obtained by a method for producing lactic acid, the method comprising: (A) a step of continuous fermentation wherein a fermentation culture medium of a microorganism having an ability of lactic acid fermentation is filtered through a porous membrane having an average pore size of not less than 0.01 µm and less than 1 µm with a transmembrane pressure difference within the range of 0.1 to 20 kPa, and the permeate is collected, while retaining the non-permeated liquid in or returning the non-permeated liquid to the culture, and adding a fermentation feedstock to the culture; (B) a step of filtering the permeate obtained in Step (A) through a nanofiltration membrane; and (C) a step of distilling the permeate obtained in Step (B) under a pressure of not less than 1 Pa and not more than atmospheric pressure, at 25°C to 200°C to recover lactic acid; comprises only small amounts of impurities, and a polylactic acid obtained using the lactic acid as a raw material has excellent thermal stability, mechanical strength and hue.

    Abstract: High purity butanol can be manufactured by means of the disclosed butanol manufacturing method which comprises: a manufacturing step (A) wherein a butanol-containing solution is filtered by being passed through a nano-filtration membrane, and the butanol-containing solution is collected from the permeation side; a manufacturing step (B) wherein the butanol-containing solution obtained in step (A) is concentrated by being passed through a reverse osmosis membrane, and separated into two phases, namely a butanol phase and a water phase; and a manufacturing step (C) wherein butanol is collected from the butanol phase obtained in step (B).
