Citric acid is very important in our lives. It is added to food as a type of preservative to prevent odors and contamination of fruits, so it is used in laboratories as anti- oxidation. Due to this importance and the increasing use of the growing population, the matter needed to think about the production of this acid industrially and required studies and researches to achieve the optimal method of economic, composition and quality as well as the quantity produced from this acid, all these are linked with the factor of time. In this research, this industry was studied in a type of (Stirred Tank Reactor), in addition to the study of the materials used, their ratios and the time taken to produce the highest value of citric acid and at constant temperature.
