Flash Chemistry: Fast Chemical Synthesis in Flow Microreactors

The length of time that the solution remains inside the reactor channels—the residence time—can be greatly reduced by adjusting the length of the channels in flow microreactors. This feature is extremely useful in controlling reactive species. Unstable short-lived reactive species can be generated and transferred to another location to be used in the next reaction before they decompose. Therefo...

A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

Kinetic Studies of the Catalytic Oxidation of Toluene to Benzoic Acid in the Liquid Phase

The catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. Low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. The dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. It has been suggested that liquid phase oxidation of t...
