POLYETHERPOLYOL AND PRODUCTION METHOD THEREOF
-
Paragraph 0080, (2016/10/08)
PROBLEM TO BE SOLVED: To provide a method of efficiently producing a polyetherpolyol, and a novel polyetherpolyol compound obtained by the production method. SOLUTION: A compound represented by the specified general formula (1) is subjected to hydrogenation reduction in the presence of a hydrogenation catalyst to produce a polyetherpolyol represented by the specified general formula (2). In the formulas (1) and (2), R1 to R5 may be identical to or different from each other and represent C1-6 linear or branched alkyl groups. COPYRIGHT: (C)2016,JPOandINPIT

-
Paragraph 0109; 0110, (2016/04/19)
A method for producing a polyol-ether compound, wherein a compound represented by the following formula (1) is subjected to hydrogenation reduction in the presence of a hydrogenation catalyst to obtain a polyol-ether compound having a skeleton represented by the following formula (2): wherein R1 and R2, which may be the same as or different from each other, each represent a linear or branched alkyl group having 1 to 6 carbon atoms; and R3 represents a linear or branched alkyl group having 1 to 6 carbon atoms or a hydroxymethyl group.
PROCESS FOR PRODUCTION OF FLAKE-LIKE DRIED 2-(5-ETHYL-5-HYDROXYMETHYL-1,3-DIOXAN-2-YL)-2-METHYLPROPAN-1-OL

Page/Page column 6, (2009/08/15)
A method for producing flake-like dried DOG by making DOG containing from 10 to 50 % by mass of a liquid go through a continuous melt-drying step of a specified condition and then making it go through, as a next step, a vacuum-drying step of a specified condition or a ventilation-drying step of a specified condition while holding a molten state thereof, to obtain DOG in which the liquid in DOG is reduced to not more than 0.5 % by mass (dried DOG), and flaking the obtained dried DOG in a flake production step.
