Separating organic compounds, especially pharmaceutical or cosmetic active agents, by treating substrate, e.g. plant or animal material, with extractant comprising fluorinated compound(s)

摘要

Separation of organic compound(s) (I), useful as active agents, from a (I)-containing substrate (A) comprises treating (A) with an extractant (B) comprising at least one fluorinated compound (II) having a b. pt. of 25[deg]C or more under atmospheric conditions, to give a fraction containing (I) and (II). Independent claims are included for: (1) production of a (I)-containing pharmaceutical or cosmetic product, involving separation of (I) by the above process; (2) the use of the (II)-containing extractant (B) as an excipient for pharmaceutical or cosmetic products; (3) pharmaceutical or cosmetic products comprising (I) as active agent and (II) as excipient, and (4) the use of (II) as solvent for dewaxing concrete.
