Abstract: N,N,N',N'-Tetracyanomethyl-1,3-diaminopropane is prepared by a reaction of 1,3-diaminopropane and formaldehyde and a compound giving cyanide ions in an aqueous medium, a) by reacting 1,3-diaminopropane, formaldehyde and the compound giving cyanide ions first in the weakly acidic range and at a temperature of 20-60@C to give N,N'-dicyanomethyl-1,3-diaminopropane and b) completing the cyanomethylation to give the tetracyanomethyl compound in the strongly acidic range at a temperature of 40-80@C.

Abstract: Alkanes substituted by chlorine atoms and/or sulfochloride groups are prepared by reacting alkanes with chlorine, with or without sulfur dioxide, in a particular throughput ratio, in a reaction chamber inclined to the horizontal, the starting materials being passed through the reaction chamber in co-current, from below. The substituted alkanes or paraffins obtainable by the process of the invention are pesticides, plasticizers, solvents and starting materials for the preparation of such products, as well as of fat liquors, detergents, lubricating oils, synthetic resins and slip agents.

Abstract: The parent patent describes a method of carrying out exothermic reactions between a gas and liq in the presence of solid catalysts; the gas and liq pass in parallel flow through a long reaction vessel contg packing, the quantity of liq passed through the vessel being such that, with const gas flow the increase in press difference between the vessel ends is >=2- fold, but the fluctuations in press difference normally caused by pulsation are eliminated. In the Patent of Addition, the method is applied to reactions which do not take place in the presence of solid catalysts, but which occur spontaneously or in the presence of dissolved or finely suspended catalysts, opt without special heat conditioning; instead of the catalyst, any kind of packing is used for the reaction vessel.
