摘要： Hexamethylcyclotrisiloxane is prepared by heating linear, branched, or cross-linked organopolysiloxanes containing at least 50 mol percent of dimethylsiloxane units to at least 350.degree. C. in the absence of substances which attack the siloxane group during heating and simultaneously distilling off the cyclic dimethylpolysiloxanes thus formed.The hexamethylcyclotrisiloxane thus prepared is an excellent carrier for fragrant materials, especially where the carrier is present in admixture with other carrier substances such as tetramethylcyclobutanedione.

摘要： This invention relates to silanes of the general formulaR.sub.n Si(OCR.sub.2.sup.1 COZR).sub.4-nwhere R represents the same or different monovalent hydrocarbon radicals or substituted monovalent hydrocarbon radicals, R.sup.1 is hydrogen or the same as R, Z is oxygen or the group ##STR1## where R.sup.1 is the same as above, n is 0 or 1 and oligomers thereof. These silanes are prepared by reacting silanes of the general formulaR.sub.n SiX.sub.4-nwhere R and n are the same as above and X represents the same or different hydrolyzable atoms or condensable groups other than RCOCR.sub.2.sup.1 CO groups, with alpha-hydroxycarboxylic acid esters or amides. The silanes, which have at least three condensable groups per molecule, may be mixed with a diorganopolysiloxane containing terminal condensable groups and at least one additional substance to prepare compositions which are storage-stable under anhydrous conditions, but crosslink when exposed to moisture at room temperature to form elastomers.
