Latest Patents
John D. Super holds a patent for a method that controls color formation during the production of polytetramethylene ether. This patent, titled "Method for controlling color formation during polytetramethylene ether," outlines a process for removing precursors, such as low boiling alkyl glycols, to eliminate undesirable color-forming acetal impurities from technical grade 1,4-butanediol/2-methyl-1,4-butanediol mixtures. The process involves distillative topping of the diol mixture prior to ring closing cyclization, resulting in a tetrahydrofuran/3-methyl tetrahydrofuran mixture that can be polymerized into polytetramethylene glycol ether polymers. This innovative method is particularly useful for producing THF and PTMEG with an APHA color index of nearly zero.
