1. The method of producing complex manganese-zinc ethylene-bis-dithiocarbamate consists in carrying out a reaction of ethylene-di-amine with a surplus of carbon disulphide, in the presence of alkaline metal hydroxide or anion, followed by the precipitation of manganese ethylene-bis-dithiocarbamate in the presence of a dispersing agent. Then, the precipitate is contacted with a solution of a zinc salt. Characterized in that: Imides with the general formula 1 are used as the dispersing agent. In the formula: n is equal to 1 to 6; X refers to a radical of an amide of an aliphatic acid with formula 2, where: R1 refers to an alkyl radical with 12 to 24 atoms of carbon, or X refers to a radical of an amide of alkenyl succinic acid with formula 3, where R2 is an alkenyl radical with 3 to 160 atoms of carbon, or X refers to a radical of imidazoline with formula 4, where R3 refers to an alkyl radical with 12 to 24 atoms of carbon. The amount of the dispersing agent is equal to 5-20 percent by mass of the initial amount of ethylene-diamine. |
