| titleOfInvention | Tetrafluoroethane composition for a refrigerator |
| abstract | A tetrafluoroethane composition for a refrigerator, which comprises a tetrafluoroethane and at least one polyether selected from the group consisting of: R2-O-(R1O)l-R3 (1) (see formulas II and III) wherein R1 is an alkylene group, each of R2, R3, R4, R5, R6, R7 and R8 which may be the same or different is a hydrogen atom, an alkyl group, an aralkyl group, an aryl group, an acyl group, a glycidyl group, -SO2R9, (see formula IV) (see formula V) or -Y1~(OR1)p~OR12 wherein R1 is as defined above, each of R9, R10, R11 and R12 is an alkyl group, an aralkyl group or an aryl group, and Y1 is a residue of a dicarboxylic compound having at least 3 caroon atoms, provided that at least one of R2 and R3 and at least one of R4 and R5 are not hydrogen atoms, and when R2 is a hydrogen atom, an alkyl group for R3 has 1 or 2 carbon atoms, and when R3 is a hydrogen atom, an alkyl group for R2 has 1 or 2 carbon atoms, l, m, n and p which may be the same or different are integers which bring the kinematic viscosity of the compounds of the formulas (1) to (3) to a level of from 5 to 300 cSt at 40°c, X1 is a residue obtained by removing hydroxyl groups from a dihydroxy,compound or a dicarboxylic compound, and X2 is a residue obtained by removing hydroxyl groups from a trihydroxy compound or a tricarboxylic compound. |
