1. the production method of a BDO Shuangzi di-n-octyl succinate sodium sulfonate, 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 n-Octanol again to obtain 1, the two toxilic acid di-n-octyls of 4-butyleneglycol, the two toxilic acid di-n-octyls 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.
