Claim:
A process for inhibiting hydrate formation in a gas comprising admixing the gas with a compound of the formula (1) wherein R 1 is C 1 - to C 24 -alkyl, C 2 - to C 24 -alkenyl or a C8- to C 18 -aryl radical which may be substituted by a C 1 - to C 12 -alkyl group, R 2 , R 3 independently of one another, are hydrogen, C 1 - to C 18 -alkyl, or C 5 - to C 7 -cycloalkyl, or R 2 and R 3 , including the nitrogen atom to which they are bonded, form a ring of 4 to 8 ring atoms, in which oxygen or nitrogen atoms may also be present in addition to carbon, A are identical or different C 2 - to C 4 -alkylene radicals, B is C 1 - to C 7 -alkylene, and n is an integer from 1 to 40.
