Diester-based cationic Gemini surfactant synthesis
Lauric acid propyl (2-hydroxy-3-chloro) ester intermediate (CHPL) is synthesized from epoxy chloropropane and lauric acid as raw materials, then lauric acid propyl (2-hydroxy-3-chloro) ester intermediate (CHPL) is further reacted with tetramethylethylenediamine for synthesis of title compound (CEGs). The influence of reaction time, reaction temperature and reactant dosage molar ratio on CEGs yield can be researched, the determined optimum reaction conditions for the synthesis of the target product are as follows: isopropyl alcohol is used as a reaction medium, the molar ratio of intermediate CHPL to tetramethylethylenediamine (TMED) is 2.2:1, the reaction is performed for30h at isopropyl alcohol reflux temperature, and the recovery rate is 82.2%. The performance test shows that the newly synthesized emulsifier has good emulsifying ability, the various performances of the emulsified asphalt are completely in accordance with the national standard, and the asphalt emulsifier belongs to a medium-cracking asphalt emulsifier.
