    Abstract: Basic copper chloride is produced by oxidising cuprous chloride in an aqueous solution containing at least 20% sodium chloride, by weight, with oxygen or air, the pH of the solution being maintained at 3.5 to 5, preferably at 4.0-4.5, and the temperature being 0 DEG C.-120 DEG C., preferably 60 DEG -75 DEG C. The pH range may be obtained by the addition of alkali or alkaline earth liquors, compounds which are alkaline on hydrolysis, and amines, for example by adding solutions of sodium or potassium hydroxide, calcium hydroxide, ammonia, alkylamines, alkali metal phosphates or carbonates, and sodium methylate or ethylate. A dispersing agent, for example alkaryl sulphonates, ethoxylated long chain alcohols or carboxylic acids, alkyl sulphonates, or sulphosuccinic acid esters, such as succinic acid dinonyl sulphonate, may be added.

    Abstract: 1. Technical Result Simplification of technological process. 2. Essence Substantially dust-free granules are prepared by reacting methylamine (II) with carbon disulfide and formaldehyde or by reacting the methylammonium salt of N-methyldithiocarbamic acid with formaldehyde in the presence of 0,1-10 mol diaminoalkylene of the formula R1 - NH-A-NH-R2 VI where R1 and R2 independently of one another are each hydrogen or C1-C4 alkyl and A is 1,2-ethylene, 1,3-propylene or 1,4-butylene bridge; these bridges can contain 1-4 C1-C4 alkyl groups counting to (II). The soil is disinfected from nematodes, germinating plants and soil fungi by effective amount of said granulate. 3. Field of Application Chemical industry, agriculture.
