From a 0.01 molar solution of
N-ethyl-N,N-dimethyl-3-(pentamethyldisiloxanyl)propylammonium
bromide in 0.5 mol l⁻¹ of sodium
perchlorate in the presence of a phosphate buffer to keep the pH value at 7,
white needles spontaneously began to crystallize. These white needles
were isolated and recrystallized from acetone.
