Abstract: Disclosed herein are a method of preparing a product including one or more product compounds selected from the group consisting of aliphatic polyols having three or more hydroxy groups and a total number of carbon atoms of 5 or more, a method of using compounds selected from the group consisting of aliphatic tricarboxylic acids, esters thereof, anhydrides thereof, and salts thereof as starting compounds for making the product compounds, and a method of using a heterogeneous hydrogenation catalyst in a method of preparing a product including one or more of the product compounds.

Abstract: Disclosed herein are a method of preparing a product including one or more product compounds selected from the group consisting of lactones having at least one group selected from the group consisting of carboxyl, carboalkoxy, hydroxy and carboxylate, a method of using compounds selected from the group consisting of aliphatic tricarboxylic acids, esters thereof, anhydrides thereof, and salts thereof as starting compounds for making the product compounds, and a method of using a heterogeneous hydrogenation catalyst in a method of preparing a product including one or more the product compounds.

Abstract: The present invention relates to polyester polyols comprising units derived from a) at least one component (A) carrying at least one COOH group or a derivative thereof, wherein component (A) comprises (i) at least one compound carrying two COOH groups or derivatives thereof (A1), and b) at least one component (B) carrying at least one OH group and no COOH group, wherein component (B) comprises (ii) optionally at least one compound or oligomer carrying at least three OH groups and no COOH group (B1), (iii) at least one compound carrying two OH groups (B2) of formula wherein n and m are independently from each other 0 or 1, and R1 and R2 are independently selected from the group consisting of H, CH3 and CH2CH3, and (iv) optionally at least one compound, oligomer or polymer carrying two OH groups and no COOH group, which is different from B2 (B3), and to an organic solvent-based two-component coating composition comprising a) a first component (K1) comprising (i) at least one polyester pol
