Abstract:

OXIDATION OF AL IN CONTACT WITH MERCURIC HALIDES The rate curves obtained during the oxidation of Al in contact with mercuric iodide were linear during a significant time interval. These linear portions were sometimes preceded by an induction period of low rate. An average of the slopes of the linear portions of all the oxidation rate curves gave a value of 0.136 mg O2sq- cmmin. THE CORROSION OF COPPER IN MINERAL ACIDS IN THE PRESENCE OF GROUP VIII CHLORIDES A brief survey was made of the effect of group VIII chlorides on the corrosion of Cu in HCl, H2SO4, and HNO3. No instances of accelerated corrosion were observed in these systems. Palladium was an excellent inhibitor for the corrosion of Cu in 2M HNO3.
