Organic Chemical Technology

Introduction, the sectors of organic chemical industry and the trends of their advancements in the last decades, the parts of chemical processes.

Organic chemical conversions applied frequently in industry, the 40 intermediers and solvents manufactured in the largest amount (US Top 40).

Main reactor types (multi purpose stirred vessel reactor, tubular reactor, autoclave, fluidized bed reactor, filmreactor) and typical work-up procedures (evaporation, fractionation, filtration, recrystallization, centrifugation, drying).
