The strontium ranelate drug has a good effect on the treatment of osteoporosis, and it is a common drug component in osteoporosis drugs.In the synthesis of this substance, citric acid, a basic material, is required to generate acetone dicarboxylic acid through the oxidation of concentrated sulfuric acid, and the substance is reacted by esterification, cyclization, and alkylation to generate tetra-Me ranelate, which is hydrolyzed to form salt to obtain strontium ranelate.Therefore, in the process of producing strontium ranelate, it is necessary to go through a synthesis process to finally form a finished preparationIn the process of preparation management, it is necessary to experiment on the preparation of the preparation, analyze the process of preparation and construction, and propose a scientific and reasonable synthesis and preparation method.
