    摘要： The invention involves spherical particles of magnesium alkoxide and a process for their preparation. Specifically, spherical magnesium alkoxide is produced by spray drying of an alcoholic solution of the corresponding carboxylated magnesium alkoxide and subsequent drying and decarboxylation, characterized in that the solution is sprayed via a two-material nozzle with inner atomization, which is operated in the part-load range at 10 to 30% of its capacity, into an inert accompanying gas which is under a pressure of 1.0 to 1.2 bar, has been preheated to 100.degree.-140.degree. C. and is fed cocurrently, after which the resulting finely divided carboxylated magnesium alkoxide is dried and is decarboxylated. The magnesium alkoxide is used for the preparation of a catalyst for the polymerization of .alpha.-olefins.

    摘要： Monoalkylethers of alkyleneglycols and oligoalkyleneglycols are reacted completely with terminally unsaturated alkenyl halides to form terminally mono unsaturated glycolethers as product, wherein initially a complete reaction to the corresponding alcoholate takes place with only one equivalent of alcoholate former, such as alkali metal alcoholate or hydroxide, and two equivalents of glycolmonoether, then the alcoholate is reacted with one equivalent of alkenyl halide, whereupon a mixture of the desired product and the glycolmonoether of the alkali metal halide is filtered or distilled off, then this mixture is reacted with the second equivalent of the alcoholate former, whereupon the recovery of the product takes place by distillation from the reaction mixture and then, after addition of a further equivalent of glycolmonoether to the residue from the product recovery, the reaction of the first and the subsequent steps is repeated.

    摘要： The invention relates to a process for preparing trisilylamine and polysilazanes in the liquid phase, in which ammonia dissolved in an inert solvent is initially introduced in a substoichiometric amount relative to monochlorosilane which is likewise present in an inert solvent. The reaction is carried out in a reactor in which trisilylamine formed according to the following equation 4NH3+3H3SiCl→3NH4Cl+(SiH3)3N and polysilazanes are formed. The reactor is subsequently depressurized and TSA is separated off in gaseous form from the product mixture. The TSA obtained is purified by filtration and distillation and obtained in high or very high purity. Further ammonia dissolved in an inert solvent is subsequently introduced into the reactor, using, together with the previously introduced amount of ammonia, a stoichiometric excess of ammonia relative to the amount of MCS previously present. Excess ammonia is subsequently discharged, inert gas is introduced and the bottom product mixture from the reactor is passed through a filter unit, with solid ammonium chloride being separated off and a liquid mixture of polysilazanes and solvent being obtained.
