Course objectives

Fundamental laboratory methods of organic chemistry for synthesis (heating, stirring, cooling, introduction of gases, working with decrease of pressure, drying) and separation of organic compounds (filtering, crystallization, distillation, extraction). The methods are trained an the compounds synthesis of important types of organic reactions. The products are characterized by melting point, thin-layer chromathography, refractive index, and infra-red spectroscopy. The aim of the course is to teach students the basic methods of laboratory technique of organic chemistry with the aim to bring them to knowledge to synthesize compounds according with the literature information.
