多元酚类化合物作为烯类单体的阻聚剂是众所周知的。本文报导一种效力较高的阻聚剂5-叔丁基顺苯三酚的合成及其阻聚能力的测定结果。 关于5-叔丁基顺苯三酚(Ⅳ)的合成,文献上仅见两篇专利报导。Stockelbach将顺苯三酚与叔丁醇在氯化锌存在下,经叔丁基化反应而得熔点约为139℃的叔丁基顺苯三酚。另一篇Stevenst由2,6-二氯代叔丁基苯酚的碱性水解而得5-叔丁基顺苯三酚。这
Polyhydric phenolic compounds are well known as polymerization inhibitors for vinyl monomers. This article reports the synthesis of a more potent polymerization inhibitor, 5-tert-butylcatechol, and the determination of its resistance to polymerization. For the synthesis of 5-tert-butylcatechol (IV), only two patents have been reported in the literature. Stockelbach tert-Butylated catechol obtained by t-butylation of catechol and t-butanol in the presence of zinc chloride gave a melting point of about 139 ° C. Another Stevenst is a basic hydrolysis of 2,6-dichloro-tert-butylphenol to give 5-tert-butylcatechol. This
