CORROSION AND GAS HYDRATE INHIBITORS HAVING IMPROVED WATER SOLUBILITY AND INCREASED BIODEGRADABILITY.

摘要

The invention provides the compounds of the formula (1) where R1 is C1- to C22-alkyl, C2- to C22-alkenyl, C6- to C30-aryl or C7- to C30-alkylaryl, -CHR5-COO- or -O-, R2 is hydrogen -CH3 or -OH, R3, R4 are each independently C1- to C22-alkyl, C2- to C22-alkenyl, C6- to C30-aryl or C7- to C30-alkylaryl, R5 is hydrogen, C1- to C22-alkyl or C2- to C22-alkenyl, A is a C2- to C4-alkylene group, D is a C2- to C5-alkylene group which may contain one or two heteroatoms, m is a number from 0 to 30, n is a number from 1 to 18, and also their use as corrosion and gas hydrate inhibitors.
