In water each of these essentially ionizes 100%. The stronger an acid is‚ the more easily it loses a proton‚ H+. Two key factors that contribute to the ease of deprotonation

Synthesis of 1‚4-benzenedicarboxylic acid Amoco Process In the Amoco process‚ terephthalic acid is produced by oxidation of p-xylene by oxygen in air: Diagram 3.1 The process uses cobalt-manganese-bromide catalyst. The bromide source can be NaBr‚ HBr or tetrabromoethane where bromine functions as a regenerative source of free radicals. In this process‚ acetic acid is the solvent and oxygen from compressed air is the oxidant. The combination of bromine and acetic acid is found to be highly corrosive
