Aqueous-phase chemistry sulfur compounds

Cycling of inorganic bromine compounds, whereby HBr, HOBr, and BiON02 are converted back to Br2 by aqueous-phase chemistry on sulfuric acid aerosol. 

The dispersed-phase stability of the organomontmorillonite [62] was not compromised. The weight percent of quat on the montmorillonite was evaluated at 0.1, 0.15, 0.2, and 0.3%. This quat will participate with the cure chemistry during vulcanization. The aqueous SBR latex (22.4% solids supplied by Jilin Petrochemical Co. Ltd.) was blended with the organomontmorillonite aqueous dispersion. The polymer-functional montmorillonite dispersion was flocculated with 2% sulfuric acid, washed with water, and dried in an oven at 50 °C for 20h. The rubber crumb was formulated at 10 phr montmorillonite content. The rubber was compounded with a two-roll mill and cured at 150°C. The compound ingredients appear to be standard with standard concentrations.
