Abstract

Det er beskrevet tri- og tetrakarboksylsyreestere med formel (1), hvori R' og R^ uavhengig av hverandre betyr Ci-C22-alkyl, C2-C22-alkenyl, Ce-Cso-aryl- eller C7-C30 alkylaryl, og A betyr en C2-C4-alkylengmppe, B betyr en hvilken som helst substituert organisk gmppe med 3-100 karbonatomer, n betyr et tall fiia 1 til 30, m betyr 3 eller 4, hvorved strukturenhetene -NR^-R^ kan være delvis eller fiillstendig kvartemerte, og deres anvendelse som gasshydratinhibitorer.
