Industrial Production of Acetal-Based Corrosion Inhibitors

Abstract

Abstract Summary of researching results of practical application of 1,3-diheterocycloalkanes as new highly-efficient corrosion inhibitors is presented herein, made by Ufa State Petroleum Technological University and Research Institute of Fine Chemicals and Agents headed by Professor D. L. Rakhmankulov. The relevance of the problem studied is stipulated by possibilities in application of petrochemical intermediate products and waste to get multifunctional corrosion inhibitors. Researching of corrosion inhibitors with the use of acetals is demonstrated to be made in two directions: tailor-made synthesis of corrosion inhibitors of acetal type using cheap and available petrochemical stock; making corrosion inhibitors with increased protection properties and improved processing quality by blending with other substances. Under the pilot studies the process flow diagram for making industrial synthesis is proposed, and efficient operating conditions for the reaction enabling to get the best results to increase the output of the desired condensate (i.e. efficient corrosion inhibitors) are defined. Standard processing unit for making corrosion inhibitors by blending is engineered and proposed to be implemented and that was installed in some enterprises of the Republic of Bashkortostan.
