Abstract
Compositions and methods of using such compositions to inhibit the formation of gas hydrate agglomerates are provided. In certain embodiments, the methods include: contacting a fluid with a hydrate inhibitor composition that includes at least one compound having the structural formula (I) wherein R1 is hydrogen or any C1 to C8 hydrocarbon chain; each of R2 and R3 is independently a C1 to C8 hydrocarbon chain; R4 is hydrogen, a C1 to C20 hydrocarbon chain, or —CH2—CH(OH)—R5; R5 is a C1 to C50 alkyl chain or a C1 to C50 alkenyl chain; X− is a counter anion; and n is an integer from 1 to 8.
