专利号:US-3979460-A 优先权日:1974-07-01 标 题 :Process for the preparation of an organomercaptophenol from sulfur, a 2,6-disubstituted phenol, and an activated olefin or an epoxy compound 发明人:HAY ALLAN S 权利人:GEN ELECTRIC 摘要:A process for the preparation of an organomercaptophenol is described which comprises the reaction of sulfur with a 2,6-disubstituted phenol carried out in the presence of (1) a base, (2) an activated olefin or an epoxy compound, (3) and a solvent with a high dielectric constant. The organomercaptophenols produced by this process are useful as monomers in the synthesis of esters, carbonates, ethers, epoxy compounds, among many other chemicals synthesized from monohydric phenols. In addition, the oganomercaptophenols are also useful as antioxidants.
