摘要： PURPOSE:To enable the use of an inexpensive ruthenium catalyst, reduce the formation of impurities and economically and economically and advantageously produce the subject compound by hydrogenating a dialkyl isophthalate in two divided stages. CONSTITUTION:Hydrogen is introduced into the upper or lower end of a fixed bed continuous type hydrogenation apparatus filled with a ruthenium hydrogenating catalyst and a raw material dialkyl isophthalate or a hydrogenation product in the first stage or in both are then subjected to hydrogenating reaction under constant conditions. The resultant reactional product and the excess hydrogen are subsequently discharged. Hydrogen is then introduced into the upper or lower end of the fixed bed continuous type hydrogenation apparatus filled with a copper chromite hydrogenating catalyst and the reactional product in the first stage or compounds expressed by formula I (R is alkyl), formula II or III and the hydrogenation product in the first stage are hydrogenated under constant conditions to discharge 1,3-cyclohexanedimethanol and the excess hydrogen from the lower or upper end of the apparatus. Furthermore, the hydrogenation apparatus equipped with a perforated plate in the lower part thereof is preferably used. The resultant 1,3-cyclohexanedimethanol is useful as a raw material for polyester-based compounds.

摘要： PURPOSE:To increase purity of 1,4-cyclohexanedicarboxylic acid obtained through hydrogenation of terephthalic acid by using a reactor lined with a highly acid resistant or acid resistant material to prevent decreasing of a catalyst activity and subjecting to contact the product with steam. CONSTITUTION:A highly acid resistant vessel or a vessel lined with an acid resistant material is used as a reactor and a solution containing terephthalic acid is hydrogenated in the presence of a palladium catalyst(the first step). Then, the obtained solution containing 1,4-cyclohexanedicarboxylic acid is subjected to contact with steam and impure materials are removed by taking out to the steam side(the second process). 1,4-Cyclohexanedicarboxylic acid(1,4- CHDA) is obtained in this way. The hydrogenation can be carried out at >=2 to hydrogen pressure. It is preferable to use a vessel lined with glassy material as the reaction vessel. It is preferable to subject a solution containing 1,4-CHDA to countercurrently contact with steam and absorb the steam containing impurities in the alkaline solution, then reuse the steam.

摘要： PURPOSE:To obtain an improver for rising of coat of bean-jam pancake capable of stably providing a fine-grained product having good rising without paying attention to fine frothing by using lactitol as an active ingredient. CONSTITUTION:The objective improver is obtained by blending (A) 3-40wt.% (preferably 0.5-20wt.%) lactitol with (B) 60-97wt.% (preferably 8-30wt.%) saccharide other than the component A, e.g. sugar or sugar alcohol. Furthermore, as the component B, glucose, lactose, maltase erythritol, etc., is advantageously used.

摘要： PURPOSE:To obtain the subject composition, excellent in biodegradability, having high ion capturing power and useful as a detergent builder, a dyeing assistant, a sequestering agent, etc., by condensing a sugaralcohol such as sorbitol with excess succinic anhydride, etc., in the presence of pyridine. CONSTITUTION:The objective condensed composition is obtained by reacting one or more sugaralcohols such as sorbitol, mannitol, galactitol, xylitol or erythritol with succinic anhydride and/or maleic anhydride in a molar amount of >=3 times based on the sugaralcohols in the presence of pyridine in a molar amount of >=0.9 based on the acid at 90 deg.C temperature for 5hr, then allowing the resultant reactional product to cool overnight, subsequently dissolving the cooled product in water and neutralizing the resultant solution with an aqueous solution of sodium carbonate while stirring the solution. This composition providers main spots at Rf=0.22, 0.44 and 0.76 when the composition is dissolved in acetic acid and developed by the thin-layer chromatography using a mixed solvent of dichloromethane:methanol:acetic acid at 5:2:2 ratio and an infrared absorption spectrum having remarkable adsorptions at 1450, 1570 and 1740cm .
