AI Technical Summary

Technical Problem

Existing antiseptics and bactericides have problems such as high toxicity, easy volatility, environmental unfriendliness, and difficulty in effectively protecting against both metal corrosion and microbial erosion at the same time.

Method used

A novel corrosion inhibitor and bactericide was prepared by synthesizing a double-electrolyte ionic liquid, modifying it with different groups to impart positive and negative charges, improving its corrosion inhibition performance, and introducing bactericidal properties.

Benefits of technology

It achieves both improved corrosion inhibition performance and excellent bactericidal properties, while reducing environmental impact.

Abstract

The application relates to a double-electricity ionic liquid corrosion and bactericidal inhibitor with corrosion and bactericidal performance. A green, simple and environment-friendly synthesis method is explored to prepare the ionic liquid corrosion and bactericidal inhibitor. 2-bromoethyl sulfonic acid sodium (BES) is used as a base, and aminoethyl piperazine (AEP) and 4-amino pyridine (4AP) are modified on the base through bromination, so that the corrosion performance is improved, two ionic liquids are formed, the bactericidal performance is introduced through the double electricity, and finally the double-electricity ionic liquid corrosion and bactericidal inhibitor with good corrosion and bactericidal performance is obtained.
