【Abstract】 In order to grasp the development status of oleal condensation Prins reaction catalytic technology, clarify the development context and research and development hotspots of related patented technologies, and further promote the development of green and clean processes for the preparation of fine chemical intermediates. Using the IncoPat patent search and analysis platform, the application trend, life cycle, application layout, applicant situation and technical branches of patents related to the synthesis reaction technology of Prins condensation of formaldehyde with alkene were searched and analyzed worldwide. On this basis, the patent of the reaction catalyst are analyzed, the catalyst categories of the reaction are summarized, the evolution route of catalyst technology is shown, and the main applicants are analyzed. The results of the analysis showed that; Global Prins condensation technology has peaked in the past five years; Patent applications mainly come from China, Japan, the United States and the United Kingdom; The technical branches of the reaction patent mainly include synthetic chemical intermediates,pharmaceutical intermediates and fragrances; The reaction catalysts mainly include liquid acid catalyst, solid acid catalyst, solid base catalyst, etc. Among the main applicants for this reaction technology patent, the Chinese Academy of Sciences and Sinopec Shanghai Petrochemical Research Institute possess the better technical strength. Through analysis, it provides information support for relevant technology enterprises in China and provides reference for formulating patent strategies in related technology fields in China.更多还原
