Abstract
The present invention relates to compounds according to formula (Ia) or formula (Ib); wherein each W is independently selected from the group consisting of H, F, Cl, Br, I and (CY2)mCY3; each Y is independently selected from the group consisting of F, Cl, Br and I; each Z is independently selected from the group consisting of H, OH, (CW2)pCW3, CY3, OCW3, O(CW2)pCW3, OCW((CY2)mCY3)CWCW2, (CW2)pOH, polyalkylene glycol and 15 polyolester; n is an integer from 2 to 49; m is an integer from 0 to 3; p is an integer from 0 to 9; the molecular weight average (Mw) is ≤5500; and the polydispersity index is ≤1.45; compositions comprising these compounds and methods for their production.
Claims23
A composition comprising a heat transfer portion and a lubricating portion, wherein the lubricating portion comprises one or more compounds according to formula (Ia) or formula (Ib);
- wherein
- each W is independently selected from the group consisting of H, F, Cl, Br, I, and (CY2)mCY3, provided that at least one W in the compound according to formula (Ia) is (CY2)mCY3;
- each Y is independently selected from the group consisting of F, Cl, Br, and I;
- each Z is independently selected from the group consisting of H, OH, (CW2)pCW3, CY3, OCW3, O(CW2)pCW3, OCW((CY2)mCY3)CWCW2, (CW2)pOH, polyalkylene glycol (“PAG”), and polyester;
- n is an integer from 2 to 49;
- m is an integer from 0 to 3;
- p is an integer from 0 to 9;
- the weight average molecular weight (Mw) is ≤5500;
- and
- the polydispersity index is ≤1.45;
- and
- wherein the heat transfer portion comprises one or more heat transfer compounds selected from the group consisting of (hydro)fluoroolefins (HFOs), hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), perfluoroalkyl iodides, and hydrocarbons.
