Title Research on the synthesis of alkyl phenol derivatives
Abstract
This overview of bisphenol A (BPA), Bisphenol F (BPF), triphenol methane (THPM), triphenol ethane (THPE) of the synthesis method. Through single factor experiment, focusing on the molar ratio of the reactants, the catalyst and the proportional relationship between the reactants, the amount of catalyst, mild reaction time on the yield of synthesis.
Phenol and acetone as raw materials, hydrochloric acid, thioglycolic acid as the catalyst synthesis of bisphenol A; with phenol and formaldehyde as raw material, phosphoric acid as catalyst of bisphenol F, phenol, p-hydroxybenzaldehyde as the raw material, p-toluenesulfonic acid anhydrous aluminum chloride as catalyst was synthesized trisphenol methane, phenol, acetyl acetone as raw material, p-toluenesulfonic acid, mercapto acetone as the catalyst synthesis of three phenol ethane and by IR, 1H NMR, the products were characterized.
Except bisphenol A, bisphenol F, derivatives can be used outside polycarbonate, polyarylate, epoxy resin, polyether ether ketone, modified monomer in polymer synthesis.
The results show that: the optimum conditions of bisphenol and phenol molar ratio of 6:1 acetone and hydrochloric acid and thioglycolic acid as a catalyst, the reaction temperature 60 ℃, reaction time 8h, the reaction yield of 88.3%; bisphenol F, most good conditions for the phenol and formaldehyde molar ratio of 3:1 and using phosphoric acid as a catalyst, the reaction temperature is 46 ℃, reaction time 2h, conversion rate of 91.57%; three phenolic groups optimum conditions for methane hydroxybenzaldehyde: phenol molar ratio of 1 : 15, and using p-toluenesulfonic acid and anhydrous aluminum chloride as a catalyst, the reaction temperature was 45 ℃, reaction time 4h; trisphenol ethane optimal conditions for phenol and acetylacetone mole ratio of 9:1, and p-toluenesulfonic acid and mercaptopropionic acid as a catalyst, the reaction temperature is 55 º C, the reaction time 4h, the crude product yield 78.41%. Ultimately determine the conditions for the synthesis of bisphenol F easiest.
