Sustainable Chemistry 4: Modeling of Chemicals - Properties and Targeted Design (Vorlesung)

Dozent/in: Klaus Kümmerer, Marco Reich

wöchentlich | Donnerstag | 12:15 - 13:45 | 16.10.2023 - 02.02.2024 | C 40.220 Seminarraum | .

Inhalt: The module covers the background and practical application of substance evaluation using computer-based methods. Due to improvements in computational power, computer-based methods have changed the traditional way to engage in experimental science. Quantitative structure-activity relationship (QSAR) models link a property or effect, such as boiling point or toxicity, to parameters associated with chemical structure. These models can be used to assess chemical substances within the so-called in silico approach (as an analogy to the in vitro and in vivo approach). After a basic introduction, this module mainly focuses on the practical application and applicability of in silico software and assessment.

Nachhaltige Chemie 1: Konzepte der Nachhaltigen Chemie (Vorlesung) (Seminar)

Dozent/in: Vania Gomes Zuin Zeidler, Klaus Kümmerer, Oliver Olsson

wöchentlich | Donnerstag | 12:15 - 13:45 | 16.10.2023 - 02.02.2024 | C 14.102 a Seminarraum

Inhalt: Chemistry is not only a science subject but also a very important industry sector worldwide. Without Chemistry our present standard of life would be possible – just think of medical drugs, pesticides, synthetics, detergents, fertilizers, and other products - last but not least fossil fuels and materials for electronics and renewable energy. Wihout a more sustainable chemistry there will be no sustainbale development. However, many people perceive chemistry as negative, particularly under the pollution aspect. In the more developed parts of the world the unintentional emissions in the environment do not play an important role any more, thanks to legal regulations and technical procedures that avoid or eliminate emissions. Since the 1990ies it has become clear that on the one hand chemical products cause the major emissions of the chemical industry. Chemistry as a science but also an industrial sector is indispensible to reach the Sustainable development Goals. A more comprehensive view on chemistry is needed, e.g. the entire life cycle of a chemical product from the raw materials production until its disposal at the end of its usage phase must be reviewed. The young and highly innovative field of sustainable chemistry has been developed from this perception. It will be outlined in an interdisciplinary approch in the lectures of this module. While sustainable chemistry is often perceived as green chemistry, based on the reduction of waste and energy use for chemical syntheses, the lecture will introduce a more comprehensive approach on sustainable chemistry. The focus is on the following topics: - The realm of sustainable chemistry - Resources and sustainable chemistry - Green reactions and syntheses - Criteria and guiding principles for sustainable chemicals, materials and products - Benign by Design - Dissipation - Sustainable management of substance flows and material flows - New business models - The framework of Strategic Approach to International Chemicals Management (SAICM) - Chemistry related international conventions

Lecture: Sustainable and organic environmental chemistry (Vorlesung)

Dozent/in: Klaus Kümmerer

wöchentlich | Dienstag | 10:15 - 11:45 | 16.10.2023 - 02.02.2024 | C HS 3

Inhalt: Basics of organic chemistry (substance groups, functional groups, physicochemical properties such as reactivity, solubility, boiling point etc.) will be discussed using examples of important chemical substances and everyday products considering their chemistry and use (e.g. fuel, natural gas, solvents, pesticides, synthetic materials, flame retardants, medical drugs, scents, sugars, amino acids, dyes). The lecture will cover the basics for understanding the occurrence and behavior of organic chemicals in the environment. Additionally, the importance of the chemical industry (including sustainable development) and resource relevant topics referring to organic chemistry and to aspects of sustainable chemistry will be covered.
