Abstract

Det er blitt oppdaget en fremgangsmåte for inhibering av dannelse av hydrokarbonhydrater i blandinger av vann og et hydratdannende gjestemolekyl, hvilken involverer tilsetning av en sammensetning til blandingene i en mengde som er virksom til inhibering av dannelse av hydrokarbonhydrater under betingelser som ellers er virksomme for å danne hydrokarbon-hydratene ved fravær av reaksjonsproduktet. Sammensetningen inkluderer minst én dendrimerisk forbindelse med en midlere molekylvekt på minst 1000 atommasseenheter (amu); og minst ett stoff med lav molekylvekt som har mindre enn 1000 amu, valgt blant polyalkylenimin, polyallylamin, stivelse, sukker og polymerer eller kopolymerer av vinylalkohol eller allylalkohol; og, valgfritt, minst ett overflateaktivt middel.
