| titleOfInvention | Unsymmetrically substituted dicarboxylic acid diamido ammonium salts and their use for gas hydrate anti-agglomeration |
| abstract | The instant invention concerns a gas hydrate inhibitor comprising an N-alkyl-N'-(N",N"-dialkylammoniumalkyl)dicarboxylic acid diamide salt represented by the formula (I), wherein R is an alkyl or alkenyl group having from 8 to 22 carbon atoms, R1 is hydrogen, a C1- to C22 alkyl group or a C3- to C22 alkenyl group, R2 and R3 are each independently an alkyl group containing 1 to 10 carbon atoms or together form an optionally substituted ring having 5 to 10 ring atoms, wherein the ring may carry up to 3 substituents, R4 is hydrogen, A is an optionally substituted hydrocarbyl group containing from 1 to 18 carbon atoms, B is an alkylene group having from 2 to 6 carbon atoms, Y is NR5, R5 is hydrogen, a C1- to C22 alkyl group or a C3- to C22 alkenyl group, and M- is an anion, a process for producing a compound according to formula (I), the use of an N-alkyl-N'-(N",N"-dialkylammoniumalkyl)dicarboxylic acid diamide salt of the formula (I) as an anti-agglomerant for gas hydrates, and a method for inhibiting the agglomeration of gas hydrates which comprises the addition of an N-alkyl-N'-(N",N"-dialkylammmoniumalkyl)dicarboxylic acid diamide salt of the formula (I) to a fluid containing gas and water. |
