PROCESS FOR PREPARING A BIOLOGICALLY ACTIVE PRODUCT

The invention relates to a process for preparing a multifunction biologically active product as a concentrated suspension comprising copper oxychloride, ammonium and copper nitrate, dinitrophenol. The starting material, the copper nitrate and the chlorine hydride are ammonated slowly with ammonia gas in a first step, and with ammonia water in the second step, thereby resulting a suspension containing insoluble particles of copper oxychloride and copper hydroxide suspended in the concentrated solution of ammonium nitrate. A stabilizing agent, as well as dinitrophenol, is also added to the resulting suspension to obtain a stabilized suspension suitable for foliar application after being diluted with hard water. Inventia se refera la un procedeu de obtinere a unui produs biologic activ, cu functii multiple, sub forma de suspensie concentrata, continand oxiclorura de cupru, azotat de amoniu si cupru, dinitrofenol. Materiile prime, azotatul de cupru si acidul clorhidric se amonizeaza lent, intr-o prima etapa, cu amoniac gazos, iar in a doua etapa, se amonizeaza cu apa amoniacala, rezultand o suspensie ce contine particule insolubile de oxiclorura de cupru si hidroxid de cupru, suspendate in solutia concentrata de azotat de amoniu. La suspensia rezultata, se mai adauga un agent de stabilizare, precum si dinitrofenol, obtinandu-se o suspensie stabila, aplicabila foliar prin diluare cu apa dura.
