PERFLUORO PHOSPHATE-TYPE GAS PIPELINE DRAG-REDUCING AGENT AND METHOD OF PREPARING SAME

摘要

A perfluoro phosphate-type gas pipeline drag-reducing agent and a method of preparing same are provided. The feedstock for said perfluoro phosphate-type gas pipeline drag-reducing agent consists of aliphatic acid, pyridine compounds, fluoro phosphate, and haloalkanes, the mass ratio whereof is 2:1:1:1-2:3:1:2. A method of preparing the perfluoro phosphate-type gas pipeline drag-reducing agent is also provided. The drag-reducing agent of the present invention offers a high drag-reduction rate, is effective over a long period of time, is stable, and has no effect on the inner walls and the inner coating layers of natural gas pipelines or on the gas itself. The drag-reducing agent does not harm the environment, has excellent solubility, and can be injected in-line in atomized form.
