摘要:

Four different transport mechanisms can be applied for substance transport in TAS-procedure. Propellents are of considerable importance in “Jet” -distillation or -sublimation. The special aptitude of neutral, basic and acid propellents has been thermogravimetrically tested. Molecular sieve 4Å, saturated with water, hexamminenickel (II) chloride and malonic acid have proved to be especially favourable in comparison to the propellents employed hitherto.
