Embodiment 1
[0015] Add 93.2g (about 0.1mol) of castor oil and 40.0g (0.4mol) of concentrated sulfuric acid into the reaction vessel, stir and react at room temperature for 1.5h, then add 7.2g (0.4mol) of water, stir and react at 50°C for 1.0h to obtain hydroxyl Castor oil (about 0.1 mol). Then add 35.0g (0.38mol) glycerol, stir and react at 80°C for 6h, add 80.0g water, stir and mix evenly, cool to below 50°C, add 95.0g (0.95mol) 40% sodium hydroxide solution, Stir and react at ~55°C for 1.5h, cool down to 30°C, add 10.0g of trisodium phosphate, stir to dissolve, and obtain a composite asphalt emulsifier.
