description: The boiling points, densities, and compositions of constant boiling deuterochloric acid have been determined at pressures between 200 and 1000 mm. The boiling points, determined with apparatus similar to that used for the determination of the boiling points of hydrochloric acid, were found to differ to a very small degree from those of hydrochloric acid. The compositions were found to vary from 19.661 percent deuterium chloride at 202.5 mm to 17.146 percent at 998.4 mm; about 2.5 and 2.2 percent lower than hydrochloric acid prepared at those pressures. The densities were found to vary from 1.20034 gms per ml at 202.5 mm to 1.18774 gms per ml at 998.4 mm. The relationship between boiling point and percent composition and between density and percent composition were found to be closely linear over the range investigated. These results were correlated and compared with the data on hydrochloric acid. The difficulties in explaining the difference in the properties of the two azeotropes is pointed out, and the application of theoretical relationships is discussed.

note: THE BOILING POINTS, COMPOSITIONS, AND DENSITIES OF THE AZEOTROPES OF DEUTEROCHLORIC ACID by WOODLAND EUSTACE ERLEBACH A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in the Department of CHEMISTRY We accept this thesis as conforming to the standard required from candidates for the degree of MASTER OF APPLIED SCIENCE Members of the Department of CHEMISTRY THE UNIVERSITY OF BRITISH COLUMBIA April, 19S3 ABSTRACT The boiling points, densities, and compositions of constant boiling deuterochloric acid have been determined at pressures between 200 and 1000 mm. The boiling points, determined with apparatus similar to that used for the determination of the boiling points of hydrochloric acid, were found to d i f f e r to a very small degree from those of hydrochloric acid. The compositions were found to vary from 19.661 percent deuterium chloride at 202 .5 mm to 17.1U6 percent at 998.h mm; about 2 .5 and 2 .2 percent lower than hydrochloric acid prepared at those pressures. The densities were found to vary from 1.2003U gms per ml at 202 .5 mm to 1.1877U gms per ml at 998.h mm. The relationship between boiling point :and percent composition and between density and percent composition were found to be closely linear over the range investigated. These results were correlated and compared with the data on hydrochloric acid.
