    Abstract: Solns. (I) of mol. O2 (II) in liq. hydrocarbons (III) are produced by contacting (III) with (II) under elevated pressure in a vertical absorption zone. The novel features are as follows: (a) there is a water layer (IV) at the lower end of the absorption zone; (b) (II) is passed into (IV); (c) (III) is supplied above (IV); (d) the finely-divided (II) rising from (IV) and (III) are passed upwards at 0-50 deg.C, with thorough mixing in the absorption zone, so that no coherent gas phase develops; and (e) (I) is discharged at the top of the absorption zone. (I) is recirculated in an amt. of 2-50 times the amt. of (III) supplied. The mixt. of (III) and (II) is passed through narrow points in the absorption zone. Absorption is carried out at 10-100 bar, depending on the amt. of (IV). A small amt. of liquid is removed at the top of the absorption zone. (IV) contains salts and surfactants.
