PHARMACEUTICAL ENGINEERING Reactors and Fundamentals of Reactors Design for Chemical Reaction

Introduction A Chemical reaction is a process that results in the conversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. These reactants are characterized by a chemical change and they yield one or more products. These products are generally different from the original reactants. Chemical reactions may be of different nature depending on the type of reactants, type of product desired, conditions and time of the reaction, for example, synthesis, decomposition, displacement, percipitation, isomerization, acid-base, redox or organic reactions. These reactions are being given in Table 1, stating their area of utility, advantages, limitations and examples.
