Abstract: In a process for returning liquid in a gas stream by passing the liquid into a tube with gas flowing along the wall, (i) the liquid is passed through a ring fitted in the tube in the direction of the middle axis of the tube; and (ii) the liquid on the inside of the ring is peeled off and carried along by the gas stream.

Abstract: PCT No. PCT/EP94/01999 Sec. 371 Date Aug. 7, 1995 Sec. 102(e) Date Aug. 7, 1995 PCT Filed Jun. 20, 1994 PCT Pub. No. WO95/00525 PCT Pub. Date Jan. 5, 1995Phosphorus-containing calixarenes of the general formula I I and a process for their preparation are described. Additionally, a process for the preparation of aldehydes by the hydroformylation of C3-C20-olefins by means of rhodium or ruthenium carbonyl complexes, in which the phosphorus-containing calixarenes of the formula I are used as ligands, is described.
