In a method of absorbing COfrom a gas mixture the use of an absorption medium comprising water and at least one amine of formula (I) 

[object Object]

The invention relates to novel particulate drug-delivery systems based on a polymer support containing at least one linear, branched or cross-linked polymer in a fraction of over 50 percent by weight in relation to the total weight of the support. The system is characterized in that at least one signal substance for transport through a biological barrier and at least one active ingredient are stored, the support, signal substance and active ingredient having no covalent links and no active-ingredient specific and signal substance specific coordinative links between one another.

Drug-delivery systems

The invention is directed to a method for separating acid gases from a gas mixture in which the gas mixture is contacted with an absorption medium which comprises water and at least one amine and has a phase-separation temperature in the range from 0 to 130&#xb0; C. In addition, the invention is directed to a device which can be used for carrying out this method.

Method and device for separating acid gases from a gas mixture

To absorb a volatile substance from a gas phase in a liquid absorbent, the gas phase is brought into contact with a film of an absorbent which comprises an ionic liquid and a wetting-promoting additive. The process can be used in absorption refrigerating machines.

Process for the absorption of a volatile substance in a liquid absorbent
