Известный способ получени органосилоксициа оалканов взаимодействием органохлорсилано1В с ацетонциапгидрином (В присутст вии акцептора хлористого водорода обладает р дом недостатков: необходимостью удал ть из реа.кциоИИой смеси образующийс хлоргидрат пиридина путем фильтрации и промывки, необходимостью вести процесс при пониженной температуре в присутствии растворител , а также «едостаточной устойчивостью некоторых производных ацетонциангидрина, создающей неудобства.A known method of obtaining organosiloxy-o-alkanes by the interaction of organochlorosilano-1B with acetone cyapgidrine (In the presence of hydrogen chloride acceptor, there are several drawbacks: the need to remove pyridine hydrochloride formed by filtration and washing from a reactive mixture, and the need to remove the process at a temperature in a nitrothermal mixture. Food-resistant some acetone cyanohydrin derivatives, creating inconvenience.
