CALCIUM CARBIDE is a reducing agent. May react vigorously with oxidizing materials. The powdered mixture of the acetylide and iron oxide and iron chloride burns violently upon ignition, producing molten iron. Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305°C., respectively, [Mellor, 1946, Vol. 5, 862].


After calcium carbide is added the pressure drops, which is followed by more calcium carbide to sustain the reaction to ensure process stream of acetylene remains steady. For cooling the heat generated during the reaction, acetylene gas produced in the process is passed through the cooler condenser with pipes surrounded by water.
