Abstract
Inventia se refera la un procedeu de obtinere a sarii complexe de mangan si zinc a acidului etilenbisditiocarbamic, cu stabilitate superioara, prin interactiunea în mediu apos a sarii de amoniu a acidului etilenbisditiocarbamic cu sarurile de mangan si zinc ale acizilor anorganici. Reactia decurge la o temperatura de 20...50 degree C, sub amestecarea treptata a componentilor reactiei într-un interval de timp de peste 30 min, iar produsul obtinut din care mai mult de 50% masa sunt constituite din particule de peste 40 mium, se separa prin filtrare de solutia mama, se dilueaza cu apa pîna la formarea unei suspensii care se supune unei macinari unde pîna la obtinerea unui produs care contine cel putin 60% masa de particule cu dimensiunea de pîna la 32 miu m, dupa care produsul rezultat, se usuca într-un uscator de tipul cu pulverizare pîna la un continut de 10% apa din masa substratului, apoi se mai usuca suplimentar sub vid, sub amestecare, la o temperatura de cel mult 100 degree C si un vid de 0,133-4,0 Kpa pîna la un continut de apa de 0,2...2,0% din masa produsului.The invention relates to a process for obtaining complex manganese and zinc salts of ethylenebisdithiocarbamic acid with superior stability by the aqueous ammonium salt interaction of ethylenebisdithiocarbamic acid with manganese and zinc salts of inorganic acids. The reaction proceeds at a temperature of 20 ... 50 ° C, under the gradual mixing of the reaction components over a period of time greater than 30 minutes, and the product obtained of which more than 50% of the mass consists of particles above 40 mium , separating by filtration of the mother liquor, diluting with water until a suspension is subjected to grinding to obtain a product containing at least 60% of the mass of particles up to 32mM, after which the product the result is dried in a spray-type dryer up to 10% water content of the substrate mass, then further dried under vacuum, under stirring, at a temperature of at most 100 ° C and a vacuum of 0.133- 4.0 Kpa to a water content of 0.2 ... 2.0% by mass of the product.
