Distraction
Distraction is a compound word made up of distillation and extraction . It describes a product-friendly separation process with the help of supercritical gases. The first process step, a high pressure extraction , takes advantage of the much higher solubility of many substances in supercritical fluids . In a second step, the supercritical fluid is usually completely removed by reducing the pressure .
The process was developed in the 1960s at the Max Planck Institute for Coal Research in Mülheim an der Ruhr by the chemist Kurt Zosel and is sometimes referred to as the Zosel process. In 1978 he proposed the term destraction for the process.
Distraction is used, for example, in decaffeination .
