This study reported the design of a modular continuous coaxial mixing crystallizer (CCMC) system for the production of micro-nanoparticles of the pharmaceutical compound fluticasone propionate (FP), and the performance of the system was evaluated. Guided by experimentally determined thermodynamic and kinetic data of FP crystallization, computational fluid dynamics simulations were employed to optimize the crystallizer design, resulting in enhanced mixing efficiency occurring within 40 ms. Through a three-stage experimental protocol, the continuous crystallization process was optimized: (1) key process parameters were screened using factorial design; (2) the operational design space was mapped via response surface methodology; and (3) particle size control mechanisms were elucidated through analysis of mixing processes. Quantitative analysis identified the antisolvent-to-solution ratio as the dominant factor governing particle size distribution, attributed to its critical role in nucleation kinetics. The CCMC platform demonstrated robust and efficient operation for 25 min, delivering a single-run output equivalent to 990 doses of commercial formulation. Comparative studies revealed advantages over batch processing, including comparable powder crystallinity, improved crystal morphology, and narrower size distributions within a micro-nanometer range. The coaxial mixing crystallizer system exhibits excellence in flexibility, productivity, and material recovery.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"309 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When thermal runaway happens, it may lead to equipment damage or even explosions. Therefore, in this work, a microreactor was adopted to reduce reaction thermal risk and process conditions were optimized. Phosphotungstic acid (PTA) was used as the catalyst, and the effects of process conditions, including reaction temperature, residence time, catalyst concentration, and molar ratio on the conversion and yield were systematically investigated. The results showed that the DPSO yield could reach up to 84.3% under the condition of 0.75% catalyst loading, 25 min residence time, 70 °C reaction temperature, and H2O2–DPS molar ratio of 2. Then, apparent reaction kinetics were studied, and a kinetic model was established and validated. By varying the initial concentrations of H2O2 and DPS, the reaction was determined to be of second-order, with an activation energy of 57.5 kJ·mol–1 and a pre-exponential factor of 2.96 × 107 mol–1·L·min–1. Furthermore, the temperature distribution along the microreactor was estimated by combining the thermal equilibrium with the reaction kinetics. The results indicated that in a 1/16 in. microreactor, the reaction was nearly isothermal. Temperature distributions were also predicted for microreactors with different diameters and materials. It was demonstrated that the reaction could be safely scaled up to a 3/8 in. microreactor at a reaction temperature of 55 °C, with the maximum temperature rise remaining below 5 °C and no decline in DPSO yield. This study provided a convenient method to guide the safe sizing-up of the reaction in flow reactors.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"74 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143836950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
