Abstract: Disclosed herein is a continuous tubular reactor based conversion of acetophenones to amino substituted acetophenones wherein the nitration is carried out at ?10 to 10° C. followed by reduction to m-nitrophenone resulting in uniform output of product, said process comprising the steps of: a) Nitrating acetophenone with nitrating agent (nitration mixture or fuming nitric acid) at ?10 to 10° C.; b) Isolating m-nitro acetophenone from a mixture of o and m-nitro acetophenone and c) Reducing the m-nitro to obtain m-amino acetophenone.

Abstract: A device which can be used as a flow reactor for synthesis and for discerning the reaction kinetics as well as a flow calorimeter is a need in the art. To fulfill this need, the invention discloses a simple calorimeter that functions as a device to measure reaction kinetics, preferably heat of reaction in a continuous manner, in adiabatic as well as in isothermal conditions. The distinct advantages of the device include online determination of thermokinetic properties, continuous determination of thermokinetic properties and applicable for determination in adiabatic as well as isothermal modes. The device may function independently or may be used in combination with reactors, micro reactors or tubular reactors.

Abstract: The present invention discloses device that can generate a strong vortex in the vortex chamber which significantly enhances rate of reactions and effectiveness of waste water treatment. The present invention disclose vortex diodes with or without inserts/stabilizers as continuous flow reactors to induce cavitation to generate radicals which reduces Chemical Oxygen Demand (COD), ammoniacal nitrogen and color of waste water effectively in effluent treatments.
