Embodiment 1
[0065] Embodiment 1: the preparation of octyl benzyl trioxyethylene ether sodium acetate
[0066] (a) Preparation of Octylbenzyl Chloride
[0067] Put 0.5mol octylbenzene in the reaction kettle, then add 1mol paraformaldehyde and 0.35mol powdered anhydrous zinc chloride, add 110mL glacial acetic acid as solvent, stir vigorously and quickly pass in dry hydrogen chloride gas, at 70~ React at 80°C until hydrogen chloride is no longer absorbed, about 2 hours, cool to room temperature, separate the upper organic phase, and extract the lower acetic acid phase with petroleum ether for 2 to 3 times, combine the organic phases with 10wt% sodium carbonate and water in sequence Wash until neutral, dry with anhydrous sodium sulfate, add a little sodium bicarbonate to distill under reduced pressure, collect fractions at 165-167°C / 3.5mmHg, the yield is 75%, and it is a colorless liquid at room temperature. That 1 H NMR spectrum see figure 1 .
