The annual consumption of coconut fatty acid diethanolamide in Iran is about 3000 tons, which is used in the production of detergents such as shampoo and dishwashing liquid, and due to the growth of detergent consumption, this amount will increase, which shows the need to prepare and Its production is inside the country. In this project, in order to obtain the synthesis method of loramide, the results presented in books and articles were reviewed and by comparing different methods, an attempt was made to optimize the selected method, which ultimately led to the preparation of a better quality product. The chosen method is based on the direct reaction between the fatty acid of coconut oil and diethanolamine by the Kritchevsky method. The main advantage of this method is not using a catalyst. First, DEA is heated up to the reaction temperature and the fatty acid, which is heated to about 100oC, is added to the reactor in several steps. It is recommended to use a nitrogen atmosphere to prevent the oxidation of the fatty acid and its darkening. The reactor used in the experiments, It is glass and the reaction is done in batch. This reactor is equipped with a mechanical stirrer and a thermometer, and a suitable jacket is used to heat it and reach the reaction temperature. This reaction is exothermic, and temperature control is one of the important points in conducting the reaction, especially in industrial production. Another important point is the molar ratio of DEA to fatty acid. The higher this ratio is, the side reactions will be prevented and the product will be of better quality, so in practice, a molar ratio of 2 to 1 (DEA to FA) is used. In this plan, while examining the important and effective parameters in carrying out the reaction such as temperature, pressure, reaction time, neutral atmosphere, aging time, molar ratio and how to increase the raw materials to each other, suitable conditions for carrying out the reaction have been obtained, also by controlling The molar ratio of 1.8 to (DEA to (FA) has been used, which will have less free DEA in the product compared to the ratio of 2 to 1.
