This invention relates to organosiloxanes which have SiC-bonded ester groups and contain at least one unit of the general formula: ##EQU1## is which R represents the same or different monovalent hydrocarbon radicals having from 1 to 12 carbons atoms, which are free of aliphatic unsaturation and which may contain one ether oxygen atom; R' represents hydrogen or a methyl group (CH.sub.3) and a is O, 1 or 2. These organosiloxanes can be prepared by hydrolyzing or co-hydrolyzing silanes of the general formula:

This invention relates to organosiloxanes which have SiC-bonded ester groups and contain at least one unit of the general formula: ##EQU1## in which R represents the same or different monovalent hydrocarbon radicals having from 1 to 12 carbon atoms, which are free of aliphatic unsaturation and which may contain one ether oxygen atom; R' represents hydrogen or a methyl group (CH.sub.3) and a is 0, 1 or 2. These organosiloxanes can be prepared by hydrolyzing or co-hydrolyzing silanes of the general formula:

Organosiloxanes with SiC-bonded groups and a process for preparing the

Stabilized organopolysiloxane oils having at least one aliphatic hydrocarbon radical with at least two carbon atoms and containing rubidium and/or cesium compounds which are at least partially soluble in the oil, in which the amount of rubidium and/or cesium present in the oil is from 0.01 to 3 percent by weight, based on the weight of the oil. The stabilized organopolysiloxane oils are useful as lubricants or as additives for lubricating compositions.
