1. one kind 1, the preparation method of 4-butyleneglycol Shuangzi Aerosol OT, it is characterized in that:

  • comprise the following steps;

    maleic anhydride and 1, two hydroxy combinings on the 4-butyleneglycol carry out single-esterification and generate 1,4-butyleneglycol span carrys out acid monoester, 1,4-butyleneglycol span comes acid monoester to carry out double esterification reaction with isooctyl alcohol again to obtain 1, the two diisooctyl maleates of 4-butyleneglycol, the two diisooctyl maleates of last BDO carry out the conjugate addition sulfonation reaction with sodium bisulfite again and make product;

    Wherein, the catalyzer of double esterification reaction is carbon-based solid acid catalyst.
