Abstract:
A method for isolating 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) solids from an isolated feed slurry formed in a TMCD process comprising TMCD, a liquid phase, and impurities by (a) treating the isolated feed slurry in a product isolation zone to produce an isolated TMCD product wet cake, a mother liquor, and impurities; wherein the product isolation zone can comprise at least one rotary pressure drum filter.
