    摘要: A method for producing an alkenyl or alkynyl-containing organosilicon precursor composition, the method comprising the steps of distilling at least once a composition comprising an alkenyl or alkynyl-containing organosilicon compound having the formula R n SiR 1 4-n wherein R is selected a linear or branched C 2 to C 6 alkenyl group, a linear or branched C 2 to C 6 alkynyl group; R 1 is selected from hydrogen, a linear or branched C 1 to C 10 alkyl group, and a C 3 to C 10 cyclic alkyl group; and n is a number selected from 1 to 4, wherein a distilled alkenyl or alkynyl-containing organosilicon precursor composition is produced after distilling; and packaging the distilled alkenyl or alkynyl-containing organosilicon precursor composition in a container, wherein the container permits transmission into the container of no more than 10% of ultraviolet and visible light having a wavelength of between 290 nm to 450 nm.

    摘要: The invention relates to a method for the separation by distillation of a three- or multi-component mixture, containing at least one light volatile, at least one medium volatile and at least one heavy volatile, wherein the three- or multi-component mixture is fed to a first column, by means of which the at least one heavy volatile is separated off as a bottom fraction and a top fraction is fed to a second column, wherein, in the second column, the at least one medium volatile is separated off via a side outlet and the at least one light volatile is separated off as a top fraction, and a bottom outlet from the second column is fed to the first column again as recyclate, wherein both distillation columns have vertical partitions. The invention further relates to a corresponding apparatus.
