A process method for producing pesticide by using carbon dioxide comprises the following steps: Weighing 1, 3-cyclohexanedione substrate, catalyst and Cs2CO3 in Schleck bottle, degassing, and continuously introducing 1 atm of carbon dioxide. Add solvent and react for 48 h in an oil bath at 50° C. After the reaction was completed, post-treatment was carried out to obtain 2(a-e). The obtained acid is acylated and then added dropwise to dichloromethane solution containing aniline to react for 2 h at normal temperature. After the reaction, column chromatography was performed to obtain 3(a-e). Add 3 (a-e) into 50% concentrated sulfuric acid and reflux at 80° C. for 8 hours. Through separation, 4(a-e) was obtained. The invention has the advantages that the catalyst is simple to prepare, has high catalytic activity, can be recycled, realizes industrial circulation, and achieves the goal of sustainable production. The preparation process of 3(a-e) and 4 (a-e) is simple, with low requirements on equipment, wide sources of raw materials, low cost, low toxicity and easy industrial scale-up production.

Surfactants constructed from three synthetic building blocks that contain multiple hydrocarbon chains, ethyleneamine, and alkyl sulfonate salt groups, were shown to possess good thermal stability, and foamability, and high foam profiles. The materials are targeted for high temperature foaming applications, such as foam flooding enhanced oil recovery to improve conformance control and other oil and gas downhole foaming applications.
