USE OF ACID ANHYDRIDE ACCELERANTS FOR THE PRODUCTION OF HIGH PURITY POLYOL ESTERS

A method of producing high purity polyol esters comprises reacting a polyol with an excess amount of a linear or branched aliphatic monocarboxylic C3-20 acid to esterify less than the total amount of the polyol present to form an intermediate reaction composition having a hydroxyl value of from 7 to about 50 mg KOH/g. An anhydride of the corresponding linear or branched aliphatic monocarboxylic C3-20 acid is added to the intermediate reaction composition in an amount of from 1 to about 2.5 equivalents of available OH in the intermediate composition to form a reaction mixture. The reaction mixture is heated for 5-30 minutes or until all of the corresponding anhydride has reacted to form a reaction product. The reaction product is then de-acidified. No metal or acid catalyst or bleaching agents are present in any of the above reaction steps at a concentration above about 15 ppm.

HEXAESTER OF MONO-FORMAL BIS PENTAERYTHRITOL

To provide hexaester of bispentaerythritol monoformal, which is a mixed ester of bispentaerythritol monoformal represented by the following formula (I), and carboxylic acids: wherein the carboxylic acids comprise C9 branched aliphatic monocarboxylic acid, and any one of carboxylic acids selected from C4 to C8 aliphatic monocarboxylic acids. The hexaester is used as one component of a refrigerant oil composition, and gives excellent characteristics, such as oxidation stability, lubricity, and low temperature properties, to a refrigerant oil composition.

Ti-Crossed-Claisen condensation between carboxylic esters and acid chlorides or acids: A highly selective and general method for the preparation of various β-keto esters

Ti-crossed-Claisen condensation between a 1:1 mixture of carboxylic esters and acid chlorides promoted by TiCl4-Bu3N-N-methylimidazole proceeded successfully to give various β-keto esters in good yields with excellent selectivities (19 examples, ～48-95% yield; cross/self-selectivity = ～96/4-99/1). The present method was extended to the condensation between a 1:1 mixture of carboxylic acids and carboxylic esters (six examples, ～70-92% yield; cross/self-selectivity = ～91/9-99/1). To demonstrate the utility of the present two Ti-crossed-Claisen condensations, we performed a couple of efficient short-step syntheses of two natural, representative, and useful perfumes, cis-jasmone and (R)-muscone.
