Study on synthesis and properties of polyacrylate wax inhibitor

Abstract Synthesis and properties of polyacrylate ester paraffin inhibitior based on polyacrylate ester start from dodecanol, tetradecanol, hexadecanol, octadecanol respectively were introduced in this paper. Hexadecyl polyacrylic showed the most potent paraffin inhibition, and then the optimum reaction condition of it was ascertained. The percentage inhibition of hexadecyl polyacrylic, synthesized under the optimized conditions, reached to 79.3%. Then crosslinked polyacrylate ester paraffin inhibitiors were synthesized and screened by static wax precipitation experiment, and find the percentage inhibition of crosslinked hexadecyl polyacrylic reached to 88.4%.
