Abstract: 2-Methyl-3-(3-methylphenyl)-propan-1-ol, 2-methyl-3-(3,5-dimethylphenyl)-propan-1-ol, 1-(3-methylphenyl)-2-methylbutan-3-ol and 1-(3,5-dimethylphenyl)-2-methylbutan-3-ol, their preparation and use as fragrances.

Abstract: Compounds of the general formulae ##STR1## in which R may be a methyl or ethyl radical and R.sup.1 may be a hydrogen, methyl or ethyl radical are disclosed. Also provided as part of the present invention are processes for the preparation of the above compounds. The compounds of the invention are useful as scents.

Abstract: 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:ROOCCH.sub.2 CH(COOR)CH.sub.2 CHR'CH.sub.2 Si(CH.sub.3).sub.a X.sub.3-a'where R, R' and a are the same as above and X represents the same or different hydrolyzable atoms or groups. Also, they may be prepared by the addition of a diester of allyl succinic acid and/or methallyl succinic acid to an organosiloxane containing Si-bonded hydrogen. These new organosiloxanes may be used as lubricants for inorganic and organic fibers, metal surfaces and as hydraulic fluids.

Abstract: 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.
