Magnetic field effect on photochemical synthesis of ultrafine organosilicon particles from a gaseous mixture of trimethyl(2-propynyloxy) silane and carbon disulphide

Original language description

With the application of a magnetic field of up to 5T, sedimentary aerosol particles which were rich in organosilicon compounds were produced from a gaseous mixture of trimethyl(2-propynyloxy) silane (TMPSi) and carbon disulphide (CS2) under UV light irradiation at 313 nm. From measurements of monitoring (He - Ne laser) light intensity scattered by the aerosol particles, it was found that the nucleation process of aerosol particles was accelerated by application of a magnetic field. Analyses of FT-IR andX-ray photoelectron spectra (XPS) of the sedimentary aerosol particles revealed that under a magnetic field, incorporation of TMPSi molecules into the aerosol particles decreased, and resulted in a greater abundance of sulphur atoms in C - S bonding than in > C=S bonding. Chemical reactions between TMPSi and CS2 that were responsive to the magnetic field were briefly discussed.

Efekt magnetického pole ve fotochemické syntéze ultračistých organosilikonových částic v plynné směsi trimethyl(2-propynyloxy)silanu a sirouhlíku

Czech description

Aerosolové částice byly připraveny za současného působení magnetického pole do 5 T a UV záření o vlnové délce 313 nm na plynnou směs trimethyl(2-propynyloxy)silanu a sirouhlíku. Bylo zjištěno, že magnetické pole urychluje nukleaci částic aerosolu. Vzniklé aerosolové částice byly charakterizovány metodami FTIR a XPS. Na základě výsledků byly diskutovány chemické reakce vedoucí ke vzniku aerosolu.
