METHOD AND APPARATUS FOR PURIFYING ORGANOSILICON COMPOUNDS FROM VOLATILE COMPONENTS

FIELD: chemical or physical processes.SUBSTANCE: invention relates to methods of purifying organosilicon compounds and devices for their implementation. Disclosed is a method of purifying organosilicon compounds from volatile components, wherein a heated stream of the purified organosilicon compound is supplied in form of a bundle of multiple filaments or jets, wherein the beam axis creates a space free from filaments, wherein the desorbing agent gas stream is distributed and directed through the filament bundle axially symmetrically from the beam center to the periphery or from the periphery to the center, wherein the transverse component of the linear velocity of the gas desorbing agent during flow of each of the multiple filaments corresponds to the value of the criterion of hydrodynamic similarity Re in range from 0.01 to 5.0. Disclosed also apparatus for implementing the disclosed method, in which high degree of extraction of volatile impurities is achieved due to the fact that perforations in the tray are located in several concentric annular rows with formation on the plate of the annular perforations and the central non-perforated (solid) zone, wherein one, lower, distributor of inlet or outlet gas desorbing agent is located along the apparatus axis between the conical bottom and the perforated plate, in the lower one-third of the cylindrical housing the upper one is located concentrically in the upper part of the apparatus above the distributing device for the organosilicon compound.EFFECT: technical result is proposed method makes it possible to considerably increase extraction efficiency of volatile components from organosilicon compounds.6 cl, 2 dwg, 1 tbl, 4 ex Изобретение относится к способам очистки кремнийорганических соединений и устройствам для их реализации. Предложен способ очистки кремнийорганических соединений от летучих компонентов, при котором нагретый поток очищаемого кремнийорганического соединения подается в виде пучка множественных филаментов или струй, причем по оси пучка создается свободное от филаментов пространство, при этом газовый поток десорбирующего агента распределяют и направляют сквозь пучок филаментов осесимметрично от центра пучка к периферии или от периферии к центру, при этом поперечная составляющая линейной скорости движения газового десорбирующего агента при обтекании каждого из множественных филаментов соответствует значению критерия гидродинамического подобия Re в диапазоне от 0,01 до 5,0.
