When alcohols react with a hydrogen halide, a substitution takes place producing an alkyl halide and water: The order of reactivity of alcohols is 3° > 2° > 1° methyl. The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive). The reaction is acid catalyzed. rowcroft walkWebNov 1, 1998 · The reaction rate of hydrochloric acid with carbonate rock at acid-fracturing conditions depends on controllable variables such as injection rate and acid concentration, and variables inherent to the carbonate rock (permeability, mineral composition, etc.).
