  5. 14. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

    Författare :Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. LÄS MER
