Use of polyalkoxysiloxane base oils as lubricants

The present invention relates to the use of a polyalkoxysiloxane base oil of formula (I) or a mixture of polyalkoxysiloxane base oils of formula (I) wherein each R1 is independently C1 to C4 alkyl, or phenyl, each R2 is independently C2 to C22 alkyl or alkenyl, or phenyl, R3 is methyl or a CH2 group linked by a single bond to another R3 group, or a mixture of polyalkoxysiloxane base oils of formula (I), or a mixture of polyalkoxysiloxane base oils of formula (I), as a lubricant, where R1 is independently C1 to C4 alkyl, or phenyl, each R2 is independently C2 to C22 alkyl or alkenyl, or phenyl, R3 is methyl or a CH2 group linked by a single bond to another R3 group, the present invention relates to a method for producing a silicon-containing ring, in which two terminal silicon atoms are connected by a CH2-CH2 bridge, x is an integer between 0 and 50, y is an integer between 1 and 500 and such that the ratio of y/x is strictly greater than 0.5. # imgabs0 # 本发明涉及式(I)的聚烷氧基硅氧烷基础油或式(I)的聚烷氧基硅氧烷基础油的混合物作为润滑剂的用途，其中每个R1
