example 1

[0020] Example 1, the preparation of formula I compound

[0021] (1) Preparation of Naphthalene Acetyl Chloride

[0022]

[0023] Add 18.6g (0.1mol) of naphthalene acetic acid and 100mL of toluene to a 250mL three-necked flask respectively, and dropwise add a solution composed of 17.9g (0.15mol) of thionyl chloride and 30mL of toluene. The solvent dichloromethane and thionyl chloride were distilled off to obtain 19.4 g of light yellow oily liquid with a yield of 94.6%.

[0024] (2) preparation of formula II compound

[0025]

[0026] Add 19.8g (0.1mol) of naphthalene dicarboxylic anhydride and 6.1g (0.1mol) of ethanolamine to a 250mL three-necked flask respectively, and 100mL of water as a solvent, heat to reflux, after the reaction is complete, cool the light yellow crystalline solid filtered by suction, and dry , to obtain 23.4g, yield 97.1%.

[0027] (3) preparation of formula I compound

[0028]

[0029] Add 24.1g (0.1mol) formula II compound and 100mL ethyl a...

example 2、25

[0032] The preparation of example 2,25% formula I compound microemulsion

[0033] Add 25g of the compound of formula I, 18g of xylene, and 7g of cyclohexanone into a 250mL beaker, stir to dissolve, add 10g of AEO-3 and 15g of Nongru 600#, stir evenly, add 25g of water, and stir thoroughly for 0.5h to obtain 25% naphthalene Microemulsion of Diformamidoethyl Naphthalene Acetate Compounds.

example 3、30

[0034] The preparation of example 3,30% formula I compound microemulsion

[0035] Add 30g of the compound of formula I, 8g of xylene, and 18g of cyclohexanone into a 250mL beaker, stir to dissolve, add 17g of Nongru 1602 and 9g of Nongru 601#, stir well, add 18g of water, stir well for 0.5h, and obtain 30% Naphthalene dicarboxamido ethyl naphthalene acetate compound microemulsion.
