gold chloride decomposition temperature

Gold Monochloride or Aurous Gold Chloride “AuCl” is a salt is prepared by heating the trichloride to 185° in air for twelve hours It is nonvolatile and unaltered at ordinary temperatures and pressure by dry air even when exposed to light but begins to decompose at temperatures above 160° and the decomposition is complete if it is heated at 175° to 180° for six days or at 250

Stable under normal temperatures and pressures Conditions to Avoid Incompatible materials light excess heat Incompatibilities with Other Materials Strong bases carbonates cyanides sulfides metals Hazardous Decomposition Products Hydrogen chloride chlorine Hazardous Polymerization Has not been reported Section 11 Toxicological

GoldIII chloride traditionally called auric chloride is one of the most common compounds of has the formula Au Cl Roman numerals in the name indicate that the gold has an oxidation state of 3 which is the most stable form for gold in its compounds Gold also forms another chloride goldI chloride AuCl which is less stable than AuCl 3

An oxide gold ore was subjected to chloridehypochlorite leaching at room temperature The effects of three factors including CaOCl 2 vs NaOCl OCl − concentration and HCl concentration on gold leaching performance were investigated Due to formation of CaOCl complex in solution and hence less reactivity calcium hypochlorite produces a sluggish gold leaching kinetics taking twice
