相转移催化法合成邻苯二酚二(ω-氯代多甘醇)醚

Synthesis of catechol bis-(ω-chloropolyethyleneglycol) ether using phase transfer catalysis

在相转移催化剂存在下 ,由邻苯二酚和ω ,ω′- 二氯代多甘醇醚一步合成邻苯二酚二 (ω- 氯代多甘醇 )醚 ,探讨了催化剂、氢氧化钠浓度对产率的影响。此法较Kopolow法更简便、有效。

Catechol bis (ω-chloropolyethyleneglycol) ether was synthesized from catechol and ω,ω′-dichloropolyethyleneglycol ether in the presence of PTC catalyst.The effects of PTC catalysts and concentration of NaOH on the yield were studied.Compared with Kopolow synthesis the method was simpler and more effective.
