Lauric acid new betaine type asphalt emulsifier synthetic process
New betaine type asphalt emulsifier lauric acid-3-(N, N, N-dimethyl acetoxy ammonium chloride)-2-hydroxy propyl ester can be synthesized by three-step reaction of lauric acid, epichlorohydrin, dimethylamine and sodium chloroacetate. The new asphalt emulsifier can be synthesized, and best reaction process conditions for synthesis of the asphalt emulsifier can be obtained. The CMC value of the target product is 4.26 x 10<-4>mol / L, and is small. Under the critical micelle concentration (CMC), the surface tension is 29.11mN / M. The synthetic emulsifier is a fast crack type asphalt emulsifier, and can be widely used in the adhesive layer, fog seal layer, non solvent cold mixing, recycling of asphalt and asphalt pavement substrate stabilizing.
