    • 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.

    • 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.
    • 新型烷氧基钛(IV) - 螯合物用于改性基于硝化纤维素或其它纤维素酯衍生物的印刷油墨。 新型螯合物包括柠檬酸烷基酯作为螯合物。 与其他钛螯合物一样,它们延迟钛组分在交联反应中的众所周知的催化作用。 当用于印刷油墨时,新型钛螯合物及其醇溶液的优点在于它们本身具有无色的颜色,因此它们实际上不会使印刷油墨变色。 新型螯合物的另一个优点在于它们不会以基于苯酚的抗氧化剂引起改变效果,因此它们也可以用于印刷油墨,这些油墨应用于含有这种抗氧化剂的聚合物基材上,而不发生变色。

    • 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.

    • 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.
