Ether amine oxides, process for their preparation and their use as surfactants in the tertiary recovery of petroleum oil |
| abstract |
Etheramine oxides of the formula where RC 8 -C 20 alkyl, C 8 -C 20 alkenyl or C 4 -C 18 alkylaryl R, and R 2 are identical or different and C 1 -C 4 alkyl, x is a number from 2 to 12 and R 3 is a group of the formulas - C 2 H 4 - and / or -C 3 H 6 -. These amine oxides are produced by oxidation of the underlying ether amines of the formula RO- (R 3 O) x NR 1 R 2 . The compounds are suitable as surface-active aids in oil production. |
