Abstract
A refrigeration composition containing at least one ester formed by esterification of a hydroxycarboxylic acid component and an alcohol component, the hydroxycarboxylic acid component chosen from hydroxycarboxylic acids comprising more than one carboxylic acid group, hydroxystearic acid, hydroxylauric acid, hydroxydecanoic acid, hydroxyarachidic acid, hydroxypalmitic acid, hydroxylinoleic acid, hydroxyerucic acid, hydroxyarachidonic acid, ricinoleic acid, and combinations thereof, and the alcohol component containing at least one alcohol; and a base oil lubricant chosen from alkylbenzenes, alkylated naphthenics, polyalkylene glycols, polyvinylethers, polyalphaolefins, mineral oils, polyol esters, and combinations thereof.
Claims17
A refrigeration composition comprising:
- at least one ester, each of the at least one esters formed by esterification of only two components:
- a hydroxycarboxylic acid component and an alcohol component, the hydroxycarboxylic acid component selected from the group consisting of hydroxycarboxylic acids comprising more than one carboxylic acid group, hydroxystearic acid, hydroxylauric acid, hydroxydecanoic acid, hydroxyarachidic acid, hydroxypalmitic acid, hydroxylinoleic acid, hydroxyerucic acid, hydroxyarachidonic acid, ricinoleic acid, and combinations thereof, and the alcohol component comprising a polyalkylene glycol;
- and
- a base oil lubricant selected from the group consisting of alkylbenzenes, alkylated naphthenics, polyalkylene glycols, polyvinylethers, polyalphaolefins, mineral oils, polyol esters, and combinations thereof.
A refrigeration composition comprising:
- an ester formed by esterification of only two components:
- a hydroxycarboxylic acid component selected from the group consisting of hydroxycarboxylic acids comprising more than one carboxylic acid group, hydroxystearic acid, hydroxylauric acid, hydroxydecanoic acid, hydroxyarachidic acid, hydroxypalmitic acid, hydroxylinoleic acid, hydroxyerucic acid, hydroxyarachidonic acid, ricinoleic acid, and combinations thereof, and an alcohol component comprising a polyalkylene glycol, wherein the ester has an alkoxylate portion which comprises one or more oxide monomers higher than ethylene oxide;
- and
- a base oil lubricant selected from the group consisting of alkylbenzenes, alkylated naphthenics, polyalkylene glycols, polyvinylethers, polyalphaolefins, mineral oils, polyol esters, and combinations thereof.
