Triazole compound as well as preparation method and application thereof

Abstract

The invention relates to a copper corrosion inhibitor used in seawater or a sodium chloride solution, in particular to preparation and application of a low-toxicity and high-efficiency corrosion inhibitor for inhibiting the corrosion of metal copper and products thereof in seawater or a sodium chloride medium. A triazole compound is 4-(furan-2-methylene amine)-5-phenyl-4H-1,2,4-triazole-3-thiol shown as a structural formula in the specifications. The triazole compound can be used as a copper seawater corrosion inhibitor for performing corrosion prevention on a copper product in the seawater or the sodium chloride medium. The corrosion inhibitor has the advantages of small using amount, low toxicity, high efficiency, strong capability in durative action and wide application prospect, can be used for effectively inhibiting corrosive destruction to the metal copper.

Description

technical field The invention relates to a seawater corrosion inhibitor for copper, namely a low-toxicity, high-efficiency nitrogen-containing heterocyclic corrosion inhibitor for inhibiting the corrosion of metal copper and its products in seawater or sodium chloride medium and its application. Background technique With the continuous consumption of various resources on land, the development and utilization of marine resources has become an inevitable way to solve the current resource depletion. However, seawater is a strong electrolyte solution with strong corrosiveness, which greatly limits the development and utilization of marine resources. Therefore, only by solving the corrosion problem of metal materials in seawater can the development and utilization value of marine resources be truly reflected. Copper has excellent mechanical strength, machinability, electrical conductivity, thermal conductivity, weldability and other characteristics, and has been widely used in ...

Problems solved by technology

However, although copper ranks after hydrogen in the metal activity sequence table, and its activity is poor, copper is also extremely susceptible to corrosion damage to varying degrees in systems containing chloride ions, sulfates, nitrates and other corrosive media, thus Lose its original various performances, and even bring huge disasters

At present, although
