PROCESS FOR 2,2,4,4-TETRAMETHYLCYCLOBUTANE-1,3-DIOL CRYSTALLIZATION

摘要

A process for isolating 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) by (a) crystallizing TMCD in a crystallization zone to generate a slurry comprising TMCD solids and (b) isolating the TMCD solids in a solid liquid separation zone to generate a wet cake and a mother liquor stream.
