由丙烯酸和十二醇、十四醇、十六醇以及十八醇为原料合成聚丙烯酸高碳醇酯,通过静态结蜡法对其效果进行评价,筛选出聚丙烯酸十六醇酯作为防蜡剂,并对其合成因素以及用量等进行了考察,优化了合成工艺。在此合成条件下,其防蜡率可达到79.3%。通过添加交联剂合成了网状聚丙烯酸高碳醇酯,筛选出了交联的聚丙烯酸十六醇酯作为防蜡剂,并对交联剂用量进行了考察,在用量为2%时,防蜡效果最好,达到了88.4%。 |

Abstract: |
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%. |
