Abstract
Muconic acid monoesters of alkanediols of 2-6 carbons and of phenol are prepared by copper (II) oxidative cleavage of phenols, catechols or orthobenzoquinones. The products are useful as comonomers in polyamides and other polymers. The alkanediol or phenol is introduced into the copper (II) reactant or catalyst.
Claims10
A copper(II) reagent prepared by reacting an alcohol selected from the group consisting of phenol and alkanediols of 2-6 carbons with a paired spin copper oxide having equimolar amounts of copper and oxygen and showing no absorption by Electron Spin Resonance, said paired spin copper oxide having a relative minimum in the visible spectrum of about 565 nm and a relative maximum of about 730 nm.
The method of preparing a copper(II) reagent by reacting an alcohol selected from the group consisting of phenol and alkane diols of 2-6 carbons with a paired spin copper oxide having equal molar amounts of copper and oxygen and showing no absorption by Electron Spin Resonance, said paired spin copper oxide having a relative minimum in the visible spectrum of about 565 nm and a relative maximum of about 730 nm.
