Abstract: PROBLEM TO BE SOLVED: To provide a production process for 1,3-propanediol by hydration of acrolein in the presence of an ion-exchange resin, followed by hydrogenation of 3-hydroxypropionaldehyde, and an ion exchanger therefor. SOLUTION: A polyamine resin based on a cross-lined polyacrylamide matrix is allowed to react with acrylic acid, an acrylic acid derivative or a salt of an ω-halogenoalkanoic acid and the resultant polyaminepolycarboxylic acid resin is used as a hydration catalyst. The ion exchanger catalyst is characterized by its extremely low volume change and high whole capacity when activated and can be used in high selectivity with high space time yield.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in a high yield useful as a synthetic material by a catalytic oxidation of a C3 component. SOLUTION: This objective malonic acid or its salt can be obtained by carrying out the catalytic oxidation of the C3 component in water phase by oxygen or oxygen containing gas in the presence of a catalyst containing a noble metal selected from platinum group (e.g. Ru, Rh, Pd, Os, Ir, Pt), at pH >=6, at the temperature range of 20-60 deg.C. Easily purchasable 3-hydroxypropionaldehyde or 3-hydroxypropionic acid or their aqueous solution is used as the C3 component. The catalysts containing Palladium or Platinum is preferred as the reaction catalyst, the amount of the catalyst to the C3 component is preferably 20-50wt.%.

Abstract: Pulverous substituted natural polymers of formula Polymer-A-CH2-CH(OH)-(CH2)n-X (I) having a degree of substitution (DS) below 0.32, in which the polymer component has not been pregelatinised and which is bonded to aminoalcohol compounds via an ether or imino group, are claimed. X = NR1R2 or NR1R2R3 X ; n = 1-3; R1, R2 and R3 = 1-20C alkyl; or R1 = benzyl; A = O or NH; X = chloride, bromide, sulphate, nitrate or acetate, especially chloride. The pulverous polymers also conveniently contain 0.02-2 wt.% finely divided, hydrophobic or hydrophilic silicic acid.

Abstract: The preparation of 3-hydroxy alkanal compounds with 3-4C atoms is by hydration of acrolein or methacrolein with water in the presence of a homogenous phase catalyst at 10-100 deg C and 1-20 bar. The initial concentration of 2-alkenal is 3-30 wt.%. The catalyst has the formula RN(Z)(CH2)n-Y: Z = H, 1-6C alkyl,CH2CHMeY' or (CH2)oY'; R = H, 1-6C alkyl, Bz, Ph, w-hydroxy(1-6C alkyl),CH2CHMeY' or (CH2)oY'; Y,Y' = COOH, P(O)(OH)2, OH, pyridyl or P(O)(CH2OH)OH, where the acid groups may be in the form of their alkali,earth-alkali or ammonium salts; n = 1-6 for Y = COOH, P(O)(OH)2, pyridyl or P(O)(CH2OH)OH, or 2 or 3 for Y = OH; o = 1-6 for Y' = COOH, P(O)(OH)2, pyridyl or P(O)(CH2OH)OH, or 0, 2 or 3 for Y' = OH.
