The invention provides a gemini
quaternary ammonium salt anti-agglomerant, a synthesis method thereof, and a method for inhibiting
hydrate agglomeration. The structure of the anti-agglomerant is represented by the formula I, which is shown in the description, wherein in the formula I, the R1 represents a straight-chain
alkyl group or a branched
alkyl group with a
carbon number of 5 to 30, the R2 represents an H atom or a straight-chain
alkyl group / branched alkyl group with a
carbon number of 1 to 10, and X- represents F-, Cl-, Br-, or I-. The synthesis method comprises the following steps: making N,N-
dimethylglycine or N,N-
dimethylglycine ester carry out reactions with
epoxy chloropropane so as to obtain a
quaternary ammonium salt intermediate; and then making the
quaternary ammonium salt intermediate carry out reactions with primary amine so as to obtain the anti-agglomerant. The method for inhibiting
hydrate agglomeration comprises a step of mixing the gemini quaternary ammonium salt anti-agglomerant with three phases of oil-gas-water. The anti-agglomerant is capable of effectively inhibiting the
hydrate from agglomerating, has the characteristics of high efficiency, low consumption, stability, and economy, and is especially suitable for preventing agglomeration of hydrate during the mixed oil-gas-water transportation process.
