Because the surface tension, foaming ability, high temperature resistance, methanol resistance, salt resistance and foam shape of the single cetyltrimethylammonium chloride and cetyltrimethylammonium chloride reaction with formaldehyde are not very significant. Therefore, the product HM-CTAC and cetyl betaine were selected to optimize the compound ratio and further evaluate the performance of the compound product. The foam volume decreases gradually with the increase of temperature; in the aspect of methanol resistance: the foam volume of the compound surfactant disappears slowly under the same methanol concentration; in the aspect of salt resistance: the foam height is more stable with the increase of salt concentration in the system, and the half-life decreases gradually; the surface tension and foam microscopic: the surface tension of the compound system decreases.
