Generally gold compounds are poorly absorbed when ingested but may cause gastrointestinal symptoms including nausea, vomiting and diarrhea. No studies for inhalation exposure were found. Chlorides : Chloride toxicity varies widely; sodium chloride has very low toxicity while carbonyl chloride (phosgene) is lethal in small doses.
The invention pertains to a method for conversion of magnesium chloride into magnesium oxide and HC1, comprising the steps of providing a magnesium chloride compound to a thermohydrolysis reactor, the reactor being at a temperature of at least 300°C, withdrawing MgO from the thermohydrolysis reactor in solid form, and withdrawing a HC1 containing gas stream from the thermohydrolysis ...
Thermal dehydration and decomposition characteristics of Fe(III) chloride hydrate have been studied by both isothermal and nonisothermal methods. After the initial melting at 35–40°C both dehydration and decomposition of the salt proceed simultaneously at temperature above 100°C. At 250–300°C a stable hydrated Fe(OH)2Cl is formed representing the first plateau region in the TG curve.

A singlepulse shock tube has been used to study the kinetics of the thermal decomposition of tertbutyl chloride, bromide, alcohol, and mercaptan. The results are compared with those obtained by earlier workers who used static reaction vessels at lower temperatures. The rate constants for the unimolecular elimination reactions are k C4H9Cl=10e .

Gold(III) 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, gold(I) chloride (AuCl) which is less stable than AuCl 3.

Jul 15, 2005· The decomposition rate of aluminum chloride hexydrate (AlCl 3 ·6H 2 O) was measured as weight loss at ambient pressure and elevated temperatures up to 270 °C. Such incomplete thermal decomposition produces a porous and reactive basic aluminum chloride [Al 2 O 3 ·2HCl·2H 2 O or Al 2 (OH) 4 Cl 2 ·H 2 O] which dissolves in water to give ...
At temperatures above 170ºK irradiation results in the formation of silver and gold colloid and the conversion of aurous chloride to auric chloride. The thermal development which occurs at 423°K is attributed to the thermal decomposition of the aurous chloride phase.
