Abstract
Functional fluid systems, i.e., hydraulic fluid and heat transfer fluid systems, containing alkoxysilanol cluster compounds having the formula RSi[OSi(OR').sub.3 ].sub.2 OH wherein R is hydrogen, an alkyl, alkenyl, aryl or aralkyl group and each R' is independently selected from the same group as R with the proviso that at least a majority of R' radicals are sterically hindered alkyl groups having at least 3 carbon atoms, are described.
Claims14
In a method wherein a first mechanical effort is converted to pressure at a first location, the pressure is transmitted from said first location to a second location via a hydraulic fluid, and said pressure is converted to a second mechanical effort at said second location, the improvement which comprises using as said hydraulic fluid one which comprises an effective amount of a compound having the formula:
- ##STR2## wherein R is hydrogen, an alkyl, alkenyl, aryl or aralkyl, and each R' is independently selected from the same group as R with the proviso that at least a majority of R' radicals are sterically hindered alkyl groups having at least 3 carbon atoms.
In a method wherein heat is passed from a first heat conductor to a heat transfer fluid at a first location, the heat is transmitted from said first location to a second location, via said heat transfer fluid and said heat is passed from said heat transfer fluid to a second heat conductor at said second location, the improvement which comprises using as said heat transfer fluid one which comprises an effective amount of a compound having the formula:
- ##STR3## wherein R is hydrogen, an alkyl, alkenyl, aryl or aralkyl, and each R' is independently selected from the same group as R with the proviso that at least a majority of R' radicals are sterically hindered alkyl groups having at least 3 carbon atoms.
