The flotation recovery of sphalerite depends on the inorganic reagents concentrations in liquid phase suspension and pH. This paper presents results studies interactions iron (II) containing ions with surface water solutions at different pH levels. thermodynamic electrochemical were carried out to analyze possible sulfate a environment relate them potassium butyl xanthate sodium dibutyl dithiop...
Equilibrium Structures and Vibrational Assignments for Isoamyl Alcohol and tert-Amyl Alcohol: A Density Functional Study Wolfgang Förner and Hassan M. Badawi Department of Chemistry, King Fahd University of Petroleum and Minerals, Dhahran 31261, Saudi Arabia Supporting Information Table S1. Internal coordinate definitions of isoamyl alcohol and tert-amyl alcohol (for atom numbering see Figure 1...
A new copper-catalyzed in situ generation of aryl thiolates strategy was successfully developed for the one-pot synthesis of substituted benzothiazoles from 2-iodoanilides using xanthate as a thiol precursor. A wide range of 2-iodoanilides with both electron-releasing and electron-withdrawing groups produced the corresponding benzothiazoles in good yields. Further, this one-pot protocol was suc...
In this work, molecular tuning of metal xanthate precursors is shown to have a marked effect on the heterojunction morphology of hybrid poly(3-hexylthiophene-2,5-diyl) (P3HT)/CdS blends and, as a result, the photochemical processes and overall performance of in situ fabricated hybrid solar cells. A series of cadmium xanthate complexes is synthesized for use as in situ precursors to cadmium sulf...
coronary graphic changes typical of temporary coronary insufficiency. It is suggested that, in such cases, a slight increase of cardiac work (tachycardia) together with a decrease of blood supply (fall in blood pressure), leads to myocardial ischemia. Comparison between an exercise test and amyl nitrite inhalation in the same patients indicates similar results. Amyl nitrite inhalation may be us...
