Embodiment 1
[0047] Preparation of ZIF-67 Encapsulated Copper Ion Modified Thiazole Corrosion Inhibitor Complex
[0048] The first step: preparation of copper ion-modified 2-mercaptobenzothiazole precursor:
[0049] Firstly, 3.95g of Tris base was dissolved in 13mL of deionized water, then the volume was adjusted to 25mL with deionized water, and then the pH was adjusted to 8.8 with ammonium chloride to obtain a buffer solution. Add 69 mg (0.41 mmol) 2-mercaptobenzothiazole and 50 mg (0.21 mmol) copper nitrate trihydrate (2-mercaptobenzothiazole to copper nitrate trihydrate molar ratio is about 2:1) at room temperature into the above buffer solution and stirred at room temperature for 30 min to obtain a copper ion-modified thiazole-containing corrosion inhibitor precursor with a yield of 83%.
[0050] The above-mentioned 2-mercaptobenzothiazole and copper nitrate trihydrate have a coordination reaction between copper ions and 2-mercaptobenzothiazole active groups at a molar ratio of 2 to ...
Embodiment 2
[0057] Preparation of ZIF-67 Encapsulated Copper Ion Modified Thiazole Corrosion Inhibitor Complex
[0058] The first step: preparation of copper ion-modified 2-mercaptobenzothiazole precursor:
[0059] Firstly, 3.95g of Tris base was dissolved in 13mL of deionized water, then the volume was adjusted to 25mL with deionized water, and then the pH was adjusted to 8.8 with ammonium chloride to obtain a buffer solution. Add 104mg (0.62mmol) 2-mercaptobenzothiazole and 50mg (0.21mmol) copper nitrate trihydrate (the molar ratio of 2-mercaptobenzothiazole to copper nitrate trihydrate is about 3:1) at room temperature into the above buffer solution and stirred at room temperature for 30 min to obtain a copper ion-modified thiazole-containing corrosion inhibitor precursor with a yield of 88%.
[0060] The above-mentioned 2-mercaptobenzothiazole and copper nitrate trihydrate have a coordination reaction between copper ions and 2-mercaptobenzothiazole active groups at a molar ratio of 2...
Embodiment 3
[0067] Preparation of ZIF-67 Encapsulated Copper Ion Modified Thiazole Corrosion Inhibitor Complex
[0068] The first step: preparation of copper ion-modified 2-mercaptobenzothiazole precursor:
[0069] Firstly, 3.95g of Tris base was dissolved in 13mL of deionized water, then the volume was adjusted to 25mL with deionized water, and then the pH was adjusted to 8.8 with ammonium chloride to obtain a buffer solution. Add 138mg (0.83mol) 2-mercaptobenzothiazole and 50mg (0.21mol) copper nitrate trihydrate (the molar ratio of 2-mercaptobenzothiazole to copper nitrate trihydrate is about 4:1) at room temperature into the above buffer solution and stirred at room temperature for 30 minutes to obtain a copper ion-modified thiazole-containing corrosion inhibitor precursor with a yield of 85%.
[0070] The above-mentioned 2-mercaptobenzothiazole and copper nitrate trihydrate have a coordination reaction between copper ions and 2-mercaptobenzothiazole active groups at a molar ratio of...
