Preparation method for high-strength copper alginate aerosol catalyst

[0035] Take sixteen groups of catalysts for the orthogonal test, weigh 1.0 g (10 mmol) of phenol and 50 mg of catalyst according to the mass ratio of phenol and catalyst of 20:1, and weigh the ratio of the mass g of phenol to the volume mL of the reaction medium as 1 :30 , weigh 30 mL of water; put the weighed phenol, catalyst and water into a three-necked flask, place the three-necked flask in a constant temperature water bath, and stir under magnetic force, when the temperature reaches 70 °C, the phenol and hydrogen peroxide 2 mL (20 mmol) of hydrogen peroxide weighed at a molar ratio of 1:2 was added dropwise to the three-neck flask at a rate of 0.1 mL / min, and the reaction time was started after the addition was completed. The reaction time was 1 h, and the target product. The reaction solution after the reaction in the examples was suction filtered to separate the catalyst and the reaction solution.

[0040] Take the first group of catalysts in the orthogonal test, weigh 1.0 g (10 mmol) of phenol and 20 mg of the catalyst according to the mass ratio of phenol and catalyst of 50:1, and weigh the ratio of the mass of phenol to the volume of the reaction medium as 1:30 g / mL, weigh 30 mL of water; put the weighed phenol, catalyst and water into a three-necked flask, place the three-necked flask in a constant temperature water bath, and stir under magnetic force. When the temperature reaches 70 °C, the phenol and Hydrogen peroxide 3 mL (30 mmol) weighed with a hydrogen peroxide molar ratio of 1:3 was added drop by drop into the three-necked flask at a rate of 0.1 mL / min. target product. The reaction solution after the reaction in the examples was suction filtered to separate the catalyst and the reaction solution.

[0042] Take the first group of catalysts in the orthogonal test, weigh 1.0 g (10 mmol) of phenol and 10 mg of catalyst according to the mass ratio of phenol and catalyst of 100:1, and weigh 1:30 g according to the mass ratio of phenol and the volume of the reaction medium / mL, weigh 30 mL of water; put the weighed phenol, catalyst and water into a three-necked flask, place the three-necked flask in a constant temperature water bath, and stir under magnetic force. When the temperature reaches 30 °C, the phenol and hydrogen peroxide 1 mL (20 mmol) of hydrogen peroxide weighed at a molar ratio of 1:1 was added dropwise to the three-neck flask at a rate of 0.1 mL / min, and the reaction time was started after the addition was completed. The reaction time was 2 h, and the target product. The reaction solution after the reaction in the examples was suction filtered to separate the catalyst and the reaction solution.
