Zusammenfassung:	organic chemistry, chemical technology, lubricant materials. SUBSTANCE: invention describes oligodiethylethyloctylsiloxans of branched structure of the general formula (I) R[(C2H5SiO]m[C2H5C8H17SiO]n[(CH3)3SiO0,5]a, where R is m = 18-36; n = 21-42; a = 3, 4, 6 as a base for oils and lubricants and method of their synthesis. Method of synthesis involves interaction of oligodiethylethyloctylsiloxanes of the general formula R[(C2H5SiO]m[C2H5HSiO]n[(CH3)3SiO0,5]a (II) where R is m = 18-36; n = 21-42; a = 3, 4, 6 with n-octane in the presence chloroplatinous acid in isopropanol at 120-140 C followed by distillation off of fraction with boiling point below 150 C under pressure 400-661.6 Pa. The proposed compounds can be used as a base for low-temperature oils and lubricants. EFFECT: improved lubricating properties. 2 cl, 5 ex
