Synthesis and Properties Evaluation of Polyacrylate Ester Paraffin Inhibitor

synthesis and properties of polyacrylate ester paraffin inhibitior based on polyacrylate reacted with 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 reached to 79.3%. Then crosslinked polyacrylate ester paraffin inhibitiors were synthesized and screened by static wax precipitation experiment, and the percentage inhibition of crosslinked hexadecyl polyacrylic reached to 88.4%.
