Reduction of arsenic trichloride with hydrogen

Reduction of arsenic trichloride with hydrogen The composition of an equilibrium vapor-gas mixture in the range 700–1100 K was estimated for the reaction of arsenic trichloride with hydrogen taken in excess of a = 1.0–2.5 as compared to the stoichiometry. The temperatures of the onset of arsenic condensation (dew point) were found. Kinetic parameters of the chemical reaction were determined. Optimal conditions for the reduction of arsenic trichloride with hydrogen were refined and conditions for the condensation of arsenic with the minimum fraction of the amorphous modification were found. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

The composition of an equilibrium vapor-gas mixture in the range 700–1100 K was estimated for the reaction of arsenic trichloride with hydrogen taken in excess of a = 1.0–2.5 as compared to the stoichiometry. The temperatures of the onset of arsenic condensation (dew point) were found. Kinetic parameters of the chemical reaction were determined. Optimal conditions for the reduction of arsenic trichloride with hydrogen were refined and conditions for the condensation of arsenic with the minimum fraction of the amorphous modification were found.
