The present invention relates to compounds for controlling gas hydrate formation of the formula (I) and (II) and plugging of gas hydrate forming fluids wherein R1 is selected from the group consisting of H, acetyl and carbonyl derivative; R2 is H, -OR3 or -NR4R5, where: R3 is H, C1-6-alkyl or carbonyl derivative, R4, R5 are selected from the group consisting of H, C1-18-alkyl, alkanol, alkoxy, cyclic/aromatic or alkylene. The invention further comprises compositions and method of producing the compounds of formula (I) and (II), method for controlling gas hydrate formation and plugging of gas hydrate forming fluids, and use of compounds of formula (I) and (II).
This invention provides water-based compositions which are essentially free of hydrocarbon solvents, particularly coating, ink, fountain solution, adhesive, agricultural and electronics cleaning compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of certain tri-alkylamides of citric acid of the structure
where R1, R2 and R3 are independently C1 to C18 alkyl groups.
