Technological Scheme of Obtaining Calcium Nitrite

Abstract

The experiments were carried out on a laboratory setup consisting of a glass reactor equipped with a paddle stirrer, placed in a thermostat; the rotation speed of the electric motor was regulated by a rheostat device and measured with a TM-ZM tachometer using a D-sensor 1 мм. The temperature of the water thermostat heating the reactor was maintained using a contact thermometer TK-300 and an electronic relay RT-230 z with an accuracy of ±10С.
