DEFINITION
Chemical names Chlorine
C.A.S. number 7782-50-5
Chemical formula Cl2
Formula weight 70.91
Assay The content of the vapourized liquid shall be not less than 99.5% of Cl2 (v/v) DESCRIPTION Liquid chlorine is a clear yellow liquid which on vapourizing yields a greenish yellow gas. It is gaseous at atmospheric temperatures and pressures but normally supplied under pressure in containers in which it is present in both liquid and gaseous phases. Such containers should meet appropriate requirements for the transportation and storage of hazardous gases.
Caution: Chlorine gas is a respiratory irritant. Large amounts cause coughing, laboured breathing and irritation of the eyes. In extreme cases the difficulty in breathing may cause death due to suffocation. Liquid chlorine causes skin and eye burns on contact. Safety precautions to be observed in handling the material are available, e.g., in the Chlorine Manual obtainable from the Chlorine Institute, 342 Madison Avenue, New York, N.Y. 10017, USA.
FUNCTIONAL USES Flour treatment agent, bleaching agent
