A catalyst and process for preparation of dihydroxy esters from specified hydroxy aldehydes is disclosed. In one embodiment, a catalyst liquid is provided which comprises from 10 percent to 60 percent magnesium salt of a specified alkanoic acid or acids, and from 90 percent to 40 percent of a particular alkanoic acid or acids, the molar ratio of alkanoic acid to magnesium salt being from about 1.5 to 20.3. The catalyst solution or liquid contacts or is contacted with a specified hydroxy aldehyde under suitable reaction conditions to form the desired dihydroxy ester. In another embodiment, dihydroxy esters are derived from specified hydroxy aldehydes by first forming a magnesium catalyst containing liquid by reacting magnesium or magnesium oxide, under suitable conditions, with a suitable alkanoic acid or acids, the acid or acids being provided in excess in specified molar ratios. The magnesium salt-alkanoic acid liquid produced is then employed as a catalyst liquid to convert the respective hydroxy aldehyde under suitable reaction conditions to form the desired dihydroxy ester.

Disclosed is a process for the recovery of purified hydroxypivalyl hydroxypivalate (HPHP) from a crude, HPHP containing material containing inorganic catalyst residues and low-boiling and high-boiling (with respect to the boiling point of HPHP) impurities. The purification process employs two distillation zones, a first distillation zone wherein inorganic and high-boiling impurities are removed and a second distillation zone wherein low- and high-boiling impurities are removed.

Disclosed are animal feed supplement formulations comprising (a) mixtures of calcium salts of certain volatile fatty acids and (b) coconut oil or mixtures of coconut oil with tallow. Such formulations are easily pelletizable and resistant to caking and dusting.

Animal feed supplement formulation

The present invention provides imide-containing and amide-containing polyester resins which are useful in the formulation of coating compositions and inks. The resins comprise the reaction product of an imide or amide, a polyester-forming polyol. a polyester-forming multifunctional acid or derivative thereof, and, optionally, a fatty oil or an unsaturated fatty acid derived from a fatty oil. The imide or amide is derived from a specified alkanolamine and an imide-forming or amide-forming reactant. The alkanolamine is a primary branched alkanolamine wherein the branched alkyl group preferably contains about 2 to 10 carbon atoms. A preferred alkanolamine is 2,2-dimethyl-3-amino-1-propanol.
