Abstract
Process for the preparation of alkoxymethylsilazanes of the general formula ** (see formula) ** Wherein x is an alkoxy group, which is derived from a primary or secondary alcohol with up to 4 carbon atoms and is preferably the methoxy group, and the radicals y are in each case equal to x or mean a methyl group is already 0 1, by reaction with ammonia of silanes of the general formula ** (see formula) ** Wherein x and y have the meanings indicated above, using a solvent and separating the silazanes formed from nh4cl, characterized in that the silazanes of the general formula indicated are used as solvents and then the ammonium chloride formed is washed off with water, or disilazane is distilled off from ammonium chloride, or ammonium chloride and disilazane are separated from each other by centrifugation.
