[0027] The invention provides a kind of preparation method of pH-nanometer iron and steel corrosion inhibitor, comprises the following steps:
[0028] (1) prepare palm wax and sodium hydroxide respectively; prepare the mixture of absolute ethanol and deionized water; then prepare the first deionized water;
[0029] (2) Heat and melt the prepared palm wax until clear, and pour it into the first three-neck bottle;
[0030] (3) Pour the prepared sodium hydroxide into the first portion of deionized water until it is completely dissolved, then pour it into the first three-necked bottle filled with liquid palm wax, and finally mix the prepared anhydrous ethanol and deionized water All the mixed solution is poured into the first three-necked bottle;
[0031] (4) the first three-necked bottle in the step (3) is placed in an oil bath, and then three ports of the first three-necked bottle are respectively equipped with a thermometer, an agitator and a reflux condenser, and reacted for ...
Embodiment 1
[0051]Prepare 2000 grams of palm wax and 120 grams of sodium hydroxide, prepare 500 ml of a mixture of absolute ethanol and deionized water with a volume ratio of 1:1, and prepare the first 300 ml of deionized water. Heat and melt the prepared 2000 grams of palm wax at 100°C until clear, then pour it into the first three-necked bottle. Pour 120 grams of sodium hydroxide into the first part of deionized water of 300ml until it is completely dissolved, then slowly pour it into the first three-necked bottle filled with liquid palm wax, and then add the prepared absolute ethanol and deionized water All the mixed solution was poured into the first three-necked bottle. Finally, place the first three-necked flask in an oil bath whose temperature is controlled at 105°C, install a thermometer, a stirrer, and a reflux condenser on the three ports of the first three-necked flask, and react for about 6 hours to obtain a dark red liquid . Prepare 120ml of concentrated sulfuric acid and 5...

[0054] Prepare 1600 grams of palm wax and 96 grams of sodium hydroxide, prepare 500 ml of a mixture of absolute ethanol and deionized water with a volume ratio of 1:1, and prepare the first 300 ml of deionized water. The prepared 1600 grams of palm wax is heated and melted at 100°C until clear, and then poured into the first three-necked bottle. Pour 96 grams of sodium hydroxide into the first part of deionized water of 300ml until it is completely dissolved, then slowly pour it into the first three-necked bottle filled with liquid palm wax, then add the prepared absolute ethanol and deionized water All the mixed solution was poured into the first three-necked bottle. Finally, place the first three-necked flask in an oil bath whose temperature is controlled at 106°C, install a thermometer, a stirrer, and a reflux condenser on the three ports of the first three-necked flask, and react for about 6 hours to obtain a dark red liquid . Prepare 96ml of concentrated sulfuric acid a...
