3,5-Bis-tert-butylsalicylic acid Usage And Synthesis

Chemical Properties

Off-white to beige powder

Uses

3,5-Di-tert-butylsalicylic acid was used to study long wavelength fluorescence emission of 3,5-Di-tert-butylsalicylic acid in a variety of organic solvents. It was also used to catalyze the reaction between aldehydes and silyl ketene acetals.

Application

3,5-Bis-tert-butylsalicylic acid is an important substance widely used as synthetic materials such as pressure sensitive recording paper, agriculture chemicals, antioxidants and so on. 3,5-di-tert-butylsalicylic acid and its derivatives, both metal salts and complexes, possess interesting triboelectrical properties. They are frequently used as charge control additives in dry xerographic toner at low concentrations to control the charging characteristic of toners.

Synthesis

98% concentrated sulfuric acid 400g was added to 100g methyl salicylate and 60g methanol at 0-15 °C. After cooling, added drops of butanol 100g are maintained at 15 °C. The obtained product was added to dissolve the ice water and filtered water to neutralize it to obtain 3,5 di-tert-butyl salicylic acid methyl ester. The product is input to another 1L in a three-mouth bottle by adding 40g NaOH and 200 ml water in 70-90 °C reflux 3h. Recovering ethanol solvent and cooling to 60 °C -70 °C by adding 20% dilute hydrochloric acid to pH=1. After washing, filtering, and drying for 8 hours to obtain 3,5-di-tert-butyl salicylic acid 152g, yield 92%.
