摘要： The present invention relates to a process to prepare alkylaluminoxanes by reaction of alkylaluminium with methacrylic acid or a conjugated unsaturated carbonyl-functional compoundof the formula (I) wherein each R1and R2 independently are an aliphatic hydrocarbon group, and R3 independently is the same hydrocarbon group as R1 and R2 or a hydrogen atom, and R4 isanaliphatic hydrocarbon group, a hydroxyl group or a hydrogen atomin the presence of an inert organic solvent. Additionally,it relates to the alkylaluminoxanes obtainable by the above process and their use.

摘要： The present invention relates to the use of a specific group of acylated nitrogen-containing compounds as anti-agglomerants for gas hydrates. The anti-agglomerants are surface active nitrogen-containing compounds with 1-7 nitrogen atoms, which compounds have at least two hydrophobic groups with 6-24 carbon atoms, and where the hydrophobic groups are connected to the remainder of the molecule by an amine moiety or an amide moiety, and which compounds have at least one C2-C5 acyl group; or a salt thereof. The invention also relates to a method for inhibiting the agglomeration of gas hydrates in a conduit, and compositions comprising the gas hydrate anti-agglomerant, a corrosion inhibitor and/or a paraffin deposition inhibitor.
