摘要：NOVELTY - A 1,1'-biphenyl-4,4'-dimethylene-bis(methyl-dioctadecyl ammonium bromide) gemini surfactant is new. USE - New 1,1'-biphenyl-4,4'-dimethylene-bis(methyl-dioctadecyl ammonium bromide) gemini surfactant (claimed). ADVANTAGE - The gemini surfactant has desired orientation characteristics with respect to molecules on a gas-liquid interface. DETAILED DESCRIPTION - A 1,1'-biphenyl-4,4'-dimethylene-bis(methyl dioctadecyl ammonium bromide) gemini surfactant is new. An INDEPENDENT CLAIM is included for manufacture of 1,1'-biphenyl-4,4'-dimethylene-bis(methyl-dioctadecyl ammonium bromide) gemini surfactant, which involves mixing 0.78424 g 4,4'-bis(bromomethyl)biphenyl, water and tetrahydrofuran, stirring, adding 1.44043 g N,N-dimethyl-octadecylamine, magnetically-stirring for 6 hours, washing with chloroform-acetone solution and ethyl acetate solution, recrystallizing using ethanol, and filtering.
