摘要： Disclosed is a new method for the preparation of metallic acid esters of titanium, zirconium or hafnium wherein a halide of the metal reacts with an organosilane ester, resulting in the formation of partial esters of the metallic acids. The degree of esterification of the metallic acid ester can be controlled based on the organosilane ester and it is possible to obtain complete esterification of the metal halides. The metallic acid partial esters prepared by the method are very pure, and can be separated selectively from the mixture in a simple manner. The metallic acid alkyl esters obtained can very easily be further esterified to the metallic acid tetraalkyl esters with the formation of very pure tetraalkyl esters.

摘要： A method is disclosed for the preparation of 1,2-dichloroethane in a reactor by the reaction of gaseous ethylene with chlorine dissolved in a hot, catalyst-containing, liquid circulating stream that is under elevated pressure and consists of chlorinated hydrocarbons. All of the chlorine is absorbed outside of the reactor, at a temperature above 90.degree. C., a pressure of more than 4 bar, and an average residence time of less than 120 seconds. The reaction takes place at the phase boundary surface of a dispersion produced from gaseous ethylene and the chlorine-containing, liquid, circulating stream, at an energy dissipation density of 0.05 to 1000 kilowatts per cubic meter, a temperature of 90.degree. to 200.degree. C., and a pressure of 7 to 20 bar. Iron(III) chloride is used preferably as catalyst. Oxygen is used preferably as inhibitor for preventing the formation of byproducts. The separation of the unreacted amounts of ethylene and chlorine as well as other gaseous components from the product-containing circulating stream is performed preferably in an expansion tank.

摘要： The invention concerns a homogenous, in particular multicolored plastic sheet or panel, based on ethylene vinyl acetate copolymer (EVA) as binder with a filler content of 30 to 80 wt. % and a process for producing it. In other embodiments the binder contains, in addition to the 70 to 85 wt. % of EVA, polypropylenes to improve the processability (tendency to adhere), EPDM to improve the flexibility, and polyethylenes to reduce the tendency to soiling. In the process described, several additives, each consisting of a binder containing at least some ethylene vinyl acetate copolymer, up to 80 wt. % of fillers and up to 5 wt. % of pigments, are mixed, plasticized and granulated or comminuted to form granules or chips of assorted colours which are mixed and, possibly after other processing operations, pressed to form the plastic web or plates.

摘要： Novel alkoxy titanium(IV)-chelates are used to modify printing inks based on nitrocellulose or other cellulose ester derivatives. The novel chelates comprise citric acid alkyl esters as chelate formers. They delay, as other titanium chelates do, the well-known catalytic effect of the titanium component in cross-linking reactions. When used in printing inks, the novel titanium chelates and their alcoholic solutions have the advantage that they have an insignificant color of their own, so that they practically do not discolor the printing inks. A further advantage of the novel chelates resides in that they do not enter into alteration effects with antioxidants based on phenol, so that they can also be used for printing inks which are to be applied to polymeric substrates containing such antioxidants without the occurence of discoloration.

摘要： A process for the production of homogeneous flat articles of thermoplastic synthetic resins wherein a starting mixture based on thermoplastic synthetic resins is processed into agglomerate or granulated material by a thermal pretreatment above the softening temperature and subsequently, optionally after additional intermediate steps, is mechanically comminuted to a mixture of particles having a random grain size distribution. The mixture of particles is piled continuously onto a conveyor belt to form a uniform layer and is sintered, under the action of heat up to the plasticization of the thermoplastic synthetic resin, into a coherent flat articles and is then press-molded under the effect of pressure and heat. The pourable powders or particles are formed from a blend of differently colored agglomerates or granules prepared in a predetermined mixing ratio; the blend being obtained from several colored batches of thermoplastic resin, each batch having a different color from the other and each batch being heat treated above the softening point of the thermoplastic resin. In one variation of the process, at least one liquid or pourable, meltable, colored medium is applied in predetermined patterns and penetrates into the sintered layer up to a desired depth, in particular throughout the entire layer thickness; and thereafter the dyed, sintered layer is compressed under the action of pressure and heat into a compact flat article.

摘要： In a method of preparing cyanoalkyl-akoxysilanes, which is suitable for the production of these silanes on a large technical scale, the reaction of a chloroalkyl-alkoxysilane with an alkali metal cyanide in the presence of a solvent takes place in a stirring reactor which is provided with means for loading these starting materials and with an outlet opening for the alkali metal chloride by-product, and which is connected through a bypass valve to a column with a superimposed condenser. After the reaction in the reactor has ended, first the solvent is distilled out through the column and then the main part of the cyanosilane, and then the rest of the cyanosilane is distilled out while bypassing the column. The alkali metal chloride is then removed from the reactor through a lock.
