The present disclosure discloses a calcium-based catalyst and a method for catalytically synthesizing an alkanolamide surfactant thereof, and belongs to the technical field of surfactant synthesis. In the present disclosure, the compounded calcium-based catalyst is prepared, and the calcium-based catalyst is utilized to catalyze reaction of fat and oil or fatty acid ester and alkanol amine to synthesize the alkanolamide surfactant with light color and less free alkanol amine, which facilitates application in daily chemicals. The calcium-based catalyst in the present disclosure has a slow release feature, so that the catalyst still has relatively high catalytic reaction activity in the late reaction period, it is guaranteed that the alkanol amine is converted into the alkanolamide surfactant with a high conversion rate, the conversion rate of the alkanol amine is high, the residual quantity of the alkanol amine in the product is low, and the risk of nitrosamine caused by the residual alkanol amine in the product is greatly lowered. Meanwhile, the speed in the early reaction period is greatly reduced due to control of slow release of the catalyst, and a deepened color of the product caused by poor heat transfer in the synthesis process due to excessively fast reaction in the early period is effectively avoided.

The present disclosure provides methods for forming emulsions. A method for forming an emulsion comprises: bringing a first fluid phase in contact with a second fluid phase that is immiscible with the first fluid phase to generate the emulsion comprising the plurality of droplets. The plurality of droplets may comprise (i) the first fluid phase or the second fluid phase, (ii) a first surfactant at an interface between the first fluid phase and the second fluid phase, and (iii) a second surfactant that is different than the first surfactant. Subsequent to generating the emulsion, collect or direct the plurality of droplets along a channel. Subsequent to collecting or directing the plurality of droplets along the channel, at most 5% of the plurality of droplets coalesce.
