Crystallization is a natural occurring process but also a process abundantly used in the industry. Crystallization can occur from a solution, from the melt or via deposition of material from the gas phase (desublimation). Crystals distinguish themself from liquids, gases and amorphous substances by the long-range order of its building blocks that entail the crystals to be formed of well-defined faces, and give rise to a large number of properties of the solid. Crystallization is used at some stage in nearly all process industries as a method of production, purification or recovery of solid materials. Crystallization is practiced on all scales: from the isolation of the first milligrams of a ...
This book describes the physicochemical fundamentals and biomedical principles of drug solubility. Methods to study and predict solubility in silico and in vitro are described and the role of solubility in a medicinal chemistry and pharmaceutical industry context are discussed. Approaches to modify and control solubility of a drug during the manufacturing process and of the pharmaceutical product are essential practical aspects of this book.
This conference provides a forum for discussion of the advances in the theory and practice of crystallization as it relates to the production of bulk crystalline materials.
Das Problem ist bekannt: Ein Unternehmen will eine Anlage errichten, in Betrieb nehmen oder erweitern, das langwierige Genehmigungsverfahren erweist sich jedoch als Investitionshemmnis. Die Situation spitzt sich zu, wenn eine befristete Erlaubnis für eine bereits betriebene Anlage - etwa zur Einleitung betriebsnotwendiger Abwässer - ausläuft. Eine durchaus übliche, aber informale Lösung besteht in der behördlichen Duldung vorzeitiger Maßnahmen. Der Gesetzgeber hat diese Lücke mit der Zulassung des vorzeitigen Beginns in §§ 9a WHG, 57b Abs. 1 BBergG, 33 KrW-/AbfG und § 8a BImSchG schließen wollen, wonach dem Unternehmer auf Antrag gestattet werden kann, parallel zum endgültigen Z...
