Fast ceactions cause segregation-local, transient concentration gradients-and their product distributions depend upon mixing. For certain reactions protons are important as products, reagents or even catalysts. One of the factors determining the product distribution is then the pH value, and for fas

An optimal pH control technique has been developed for multistep enzymatic synthesis reactions where the optimal pH differs by several units for each step. This technique separates an acidic environment from a basic environment by the hydrolysis of urea within a thin layer of immobilized urease. Wit
## Abstract In mixingβdisguised azo coupling reactions the protons which are released during the electrophilic substitution steps cause a pHβgradient in the reaction zone. Since, owing to the acidβbase preβequilibria, these pHβgradients also determine the local concentrations of the reactants in th
