The rapid expansion of supercritical solution (RESS) technol. was applied to recrystallize and micronize three active pharmaceutical ingredients (APIs) of monobenzone, ethylparaben, and kojic acid. All unprocessed (original) APIs had a large mean particle size over 200μm with wide particle size distribution. Supercritical carbon dioxide served as the solvent to extract each API in a high-pressure vessel. The nearly saturated supercritical solution was then expanded through a capillary spray nozzle to ambient pressure state. The APIs were recrystallized in a very short time period. The final API particles with submicron sizes were obtained with much less intensity of crystallinity. The optimal RESS process parameters and the improved result of the in vitro dissolution test for the API of ethylparaben are reported. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Name: 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Name: 4-Benzyloxyphenol
