Abstract

fluido de trabalho para um dispositivo de transferência de calor e processo para preparação de uma composição lubrificante de poliol éster. composições lubrificantes compreendendo certas misturas de ésteres de pentaeritritol, dipentaeritrol, tripentaeritritol e oligômeros de pentaeritritol maiores são idealmente adequados para uso com co~2~ como refrigerante em dispositivos de transferência de calor providos de modo que pelo menos 30% em peso dos ésteres de oligômeros de pentaeritritol contendo 4 ou mais unidades de monômero de pentaeritritol e em que a maioria dos grupos alquilcarboxilato são grupos alcanoíla c~3~-~6~ de cadeia linear, tais como n-pentanoil. a referida mistura de alquilcarboxilato de ésteres não apenas mostraram ter viscosidade maior que o esperado e miscibilidade de co~2~ excepcional, mas também possui lubricidade excelente, propriedades de construção de película e priopriedades de suporte de carga até mesmo como parte de uma solução lubrificante/co~2~.
