  1. 1. The influence of solvent composition on crystal agglomeration of paracetamol

    Författare :Eva Ålander; KTH; []
    Nyckelord :paracetamol; solvent composition; agglomeration; image analysis; principal component analysis; agglomerate strength; interfacial energy;

    Sammanfattning : This thesis deals with the influence of solvent compositionon crystal agglomeration of paracetamol. Much work has beendone on characterisation of the crystalline product.Interfacial energies have also been determined for large singlegrown crystals. LÄS MER

  3. 2. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Författare :Xiomara Holmbäck; KTH; []
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER

  4. 3. Influence of Solvent Composition on Crystal Agglomeration of Paracetamol

    Författare :Eva Ålander; Åke Rasmuson; Jean-Paul Klein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Agglomeration is an important phenomenon which often controls the particle size distribution and morphology in the crystallization of organic compounds. In this thesis the influence of solvent composition on crystal agglomeration of paracetamol is investigated. LÄS MER

  7. 5. Development of a Solvent Extraction Process for Group Actinide Recovery from Used Nuclear Fuel

    Författare :Emma Aneheim; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Partitioning; Solvent Extraction; Fission Products; TBP; BTBP; GANEX;

    Sammanfattning : When uranium is used as fuel in nuclear reactors it both undergoes neutron induced fission as well as neutron capture. Through successive neutron capture and beta decay transuranic elements such as neptunium, plutonium, americium and curium are produced in substantial amounts. LÄS MER
