The desired nonionic gemini surfactant, hydroquinone bislauryl alcohol was prepared as follows. Hydroquinone bislauric acid methyl ester (5.25 g) was dissolved in dry tetrahydrofuran (THF) at 0° C. Lithium aluminum hydride (LAH) (1.07 g) was added to the solution slowly. A large amount of hydrogen was generated. The reaction temperature was then raised to 25° C. After the reaction was stirred for an hour at this temperature, the reaction was stopped by adding ethanol to deactivate the excess LAH. The solution was mixed with water and then acidified with concentrated HCl. The final product was extracted twice with ether. The crude hydroquinone bislauryl alcohol was dried under vacuum. The product is an oily liquid (4.2 g) whose NMR spectrum agrees with the structure of the expected gemini compound. The reaction can be summarized as follows.
