| Zusammenfassung: | The invention provides a preparation method for metal complex-(3,5- di-tert-butyl salicylic acid). The preparation method comprises the steps of dissolving 3,5- di-tert-butyl salicylic acid in alkali metal hydroxide liquor, and synthesizing the metal complex-(3,5- di-tert-butyl salicylic acid) by adopting different mixing ways with metal salt liquor at 60-70 DEG C, wherein the complex-(3,5- di-tert-butyl salicylic acid) can be used as an antistatic agent and a charge control agent for powdered ink. The invention further provides a method for preparing 3,5- di-tert-butyl salicylic acid by taking the methyl salicylate as the material through Friedel-Craft reaction and hydrolysis reaction of ester. |
