Barium Dichromate

For the particle size measurements of boron and barium dichromate, components of pyrotechnic delay compns, Freeman (Ref 46) evaluated the MSA. Particle Size Analyzer versus microscopy, gravitational liq sedimentation,... [Pg.517]

Chromium-based oxidants, noteworthy for their specificity and ease of use, continue to be popular. Enayatollah Mottaghinejad of Azad University of Iran, Tehran has found (Tetrahedron Lett. 2004,45, 8823) that barium dichromate, easily prepared, smoothly oxidizes alcohols to aldehydes and ketones in refluxing acetonitrile. [Pg.93]

Barium Dichromate. See under Chromates and Dichromates. Several pyrotechnic compns contg BaCr04 are described by H.Ellem, Modern Pyrotechnics ,ChemPublg Co,NY(1961),283-4... [Pg.20]

Barium chromate. BaCrO. is only extremely slightly soluble and barium dichromate, BaCfoO-. is soluble in water. What effect rvill the addition of Ba++ ion have on the equilibrium... [Pg.530]

Barium Potassium Trichromate, 2BaCr30io- 2Clr30]o-3H20, is formed when a potassium salt is added to a chromic acid solution of barium dichromate and the mixture concentrated it crystallises in brownish-red needles, which are very deliquescent and ai-e decomposed by water. [Pg.48]

J. Thomsen, and J. Krutwig similarly treated silver chromate with hydrochloric acid. A. Mailfert found that chromium trioxide is formed when soln. of chromic salts or chromic oxide are treated with ozone. M. Prud homme and F. Binder observed that if barium chloride is added to a soln. of barium dichromate, normal barium chromate is precipitated, and potassium chloride and chromic acid remain in soln. In preparing chromic acid, V. V. Polyansky first obtained calcium chromate by addition of calcium hydroxide paste, followed by calcium chloride soln., to... [Pg.91]
