Title (EN) PHOSPHORUS-CONTAINING COMPOSITIONS FOR REFRIGERATION SYSTEMS
(FR) COMPOSITIONS A TENEUR EN PHOSPHORE POUR SYSTEMES DE REFRIGERATION
Abstract:
(EN) 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 a phosphorus-containing composition comprising at least one compound characterized by formula (1) or (2) wherein R1 and R2 are each independently hydrocarbyl groups or hydrocarbyloxyalkylene groups and R1 and R2 taken together have a total of 2 to about 24 carbon atoms excluding any oxyalkylene carbon atom; a is 0 or 1; b is 1 or 2; c is 1, 2 or 3; d is 0, 1 or 2, provided that c+d=3; if b is 1, Z is selected from the group consisting of -R5, -XR5, -N(H)R5, -N(R5)2, -C(X)R5, -CN, -S(O)R5, -S(O)2R5, -S(O)2N(R3)(R4) and ($g(a)); if b is 2, Z is -N(R5)-, X is oxygen or sulfur; Y is a hydrocarbylene group having 1 to about 20 carbon atoms; R5 is a hydrocarbyl group having 1 to about 18 carbon atoms; R3 and R4 are each independently hydrogen; or a hydrocarbyl group having 1 to about 24 carbon atoms; or R3 and R4 taken together form a heterocyclic ring. The present invention provides compositions which are useful as refrigeration liquids in refrigerators and air-conditioners including auto, home and industrial air-conditioners. The invention provides phosphorus-containing compositions which are compatible with fluorine-containing hydrocarbons used in refrigerators and air-conditioners. The phosphorus-containing compositions act as a lubricant additive for air-conditioners.
(FR) L'invention se rapporte à une composition comprenant: (A) une grande quantité d'un hydrocarbure à teneur en fluor contenant un ou deux atomes de carbone, et (B) une petite quantité d'une composition à teneur en phosphore comprenant au moins un composé caractérisé par la formule (1) ou (2), où R1 et R2 représentent chacun séparément des groupes hydrocarbyle ou des groupes hydrocarbyloxyalkylène et R1 et R2 possèdent ensemble un total de 2 à environ 24 atomes de carbone, à l'exclusion des atomes de carbone oxyalkylène; a est égal à 0 ou à 1; b est égal à 1 ou à 2; c est égal à 1, à 2 ou à 3; d est égal à 0, à 1 ou à 2, à condition que c+d=3; lorsque b est égal à 1, Z est choisi dans le groupe composé de -R5, -XR5, -N(H)R5, -N(R5)2, -C(X)R5, -CN, -S(O)R5, -S(O)2R5, -S(O)2N(R3)(R4) et ($g(a)); lorsque b est égal à 2, Z représente -N(R5)-, X représente l'oxygène ou le soufre; Y représente un groupe hydrocarbylène ayant 1 à environ 20 atomes de carbone; R5 représente un groupe hydrocarbyle ayant 1 à environ 18 atomes de carbone; R3 et R4 représentent chacun séparément l'hydrogène; ou un groupe hydrocarbyle ayant 1 à environ 24 atomes de carbone; ou R3 et R4 forment ensemble une chaîne fermée hétérocyclique. L'invention se rapporte à des compositions qui sont utilisables comme liquides de réfrigération dans des réfrigérateurs et des climatiseurs tels que des climatiseurs pour automobiles, des climatiseurs à usage domestique et des climatiseurs à usage industriel. L'invention se rapporte à des compositions à teneur en phosphore qui sont compatibles avec des hydrocarbures à teneur en fluor utilisés dans les réfrigérateurs et des climatiseurs. Des compositions à teneur en phosphore servent d'additif de lubrifiant pour climatiseurs.
