This invention relates to a composition comprising: (A) a major amount of a fluorine-containing hydrocarbon containing one or two carbon atoms; and (B) a minor amount of at least one soluble boron-containing composition prepared by reacting a boron source with a monohydroxy alcohol, an alkylene glycol, a polyoxyalkylene glycol, hydrocarbyloxyalkylene glycol, a hydrocarbylcarbonyl polyoxyalkylene glycol, a hydroxy amine, or mixtures of two or more thereof, provided that the boron-containing composition is substantially free of hydroxyl groups. The present invention provides compositions which are useful in refrigerators or air conditioners including auto, home and industrial air conditioners. The invention provides boron-containing compositions which are compatible with fluorine-containing hydrocarbons used in refrigerators and air conditioners.
A composition, comprising:
The composition of 1 wherein the boron-containing composition is prepared from a mixture of an N-alkyl alkanolamine and an alkyl terminated polyoxyethylene glycol or polyoxypropylene glycol, or mixtures thereof.
The composition of 1 wherein the boron-containing composition is formed by reacting the boron source with an amount of the mixture of an alkyl terminated polyoxyalkylene glycol and an N-alkyl alkanolamine which provides three hydroxyl groups for every one boron atom.
A composition, comprising:
