The students are able to

understand and be able to apply the basic rules for occupational safety in the organic preparative laboratory;

master various techniques for the purification of organic compounds, including distillation, filtration, recrystallization, precipitation, sublimation and extraction with work-up to acidic, basic and neutral compounds;

carry out stoichiometric calculations for organic chemical reactions and use chemical databases and formula characterization programs for support.

Translated with DeepL.com (free version)

Safety in the organic preparative laboratory (basic rules, deactivation and disposal of reactive chemicals, general rules of conduct); materials for laboratory materials, glassware and construction of standard reaction apparatus, ground joints and screw connections; characterization of organic compounds using melting point, boiling point, refractive index and specific rotation value; basic techniques for the purification of organic compounds (distillation under various pressure conditions, filtration, recrystallization, precipitation, sublimation); Extraction with processing for acidic, basic and neutral compounds; drying of solids, solutions and solvents; special cleaning operations for absolute solvents; working with gases (reactive gases, absorption of resulting gases, protective gases); cleaning of laboratory equipment; stoichiometric calculation of organic-chemical reactions and use of chemistry-specific drawing programs, chemistry databases; selected application examples

lecture

written

Will be discussed in the first lesson.

Remarks: Due to substantial differences in the allocation of ECTS-Credits in various curricula (Bachelor’s Programme Chemistry 2008 - Bachelor’s Programme Chemistry 2023), the requirements for this course vary. Information will be provided by the instructor at the beginning of the course.
