Alkynols are important corrosion inhibitors for steel under high temperature concentrated acid conditions. After the synthesis of dimethylhexynol (S62) and methylbutynol (MB), the author continued to study the synthesis and storage method of 2-aminothiazole(MP), and improved the preparation process of potassium isobutanol catalyst, which greatly shortened the time. Under the condition of acetylene reaction, the conversion rate of butanone is 100%, and the yield of MP is 90%. The corrosion inhibition performance of MP is studied by orthogonal test, and a reasonable corrosion inhibitor formula is obtained. The experiment shows that MP containing 6 carbon atoms has better corrosion inhibition effect than MB containing 5 carbon atoms and S62 containing 8 carbon atoms, and is less affected by temperature, and is more suitable for high temperature action.
