Abstract: Magnesium ethoxide with a content of large particles, consisting of less than 40 wt. % particles with a size of not more than 500 microns and at least 60 wt. % with a particle size of more than 500 microns. An Independent claim is also included for a process for the production of this material by reacting optionally activated metallic magnesium with ethanol in the liquid phase under pressure at above 78 degrees C and then isolating the product.

Abstract: Preparation of organoalkoxy siloxanes involves mixing at least one organotrichlorosilane, water and alcohol with simultaneous removal of hydrogen chloride and passage of the crude product following an average residence time of 0.5-180 minutes to a reaction-distillation column at 50-200 degrees C to separate volatile components as an overhead product and yield the organoalkoxysiloxanes at the sump product. Preparation of organoalkoxy siloxanes of formula (I) involves: (A) mixing: (1) at least one organotrichlorosilane, optionally mixed with tetrachlorosilane; (2) water; and (3) alcohol in a molar ratio of (A1):(A2):(A3) of 1:0.59-0.95:0.5:100 respectively at 0-150 degrees C with simultaneous removal of hydrogen chloride from the system and passage of the crude product following an average residence time of 0.5-180 minutes to (B) a reaction-distillation column at 50-200 degrees C to separate volatile components as an overhead product and yield the organoalkoxysiloxanes at the sump product. R, R'' = methyl, ethyl, vinyl, n-propyl, i-propyl, gamma -chloropropyl, n-butyl, i-butyl, n-pentyl, i-pentyl, n-hexyl, n-heptyl, i-heptyl, n-octyl, i-octyl, hexadecyl, octadecyl or alkoxy; R' = methyl or ethyl; n, m = 0-20; and n+m = at least 2.
