Achieving practically zero discharge for an acrylic acid plant by a metalorganic precipitation process

摘要

G.Y.Guo of Shanghai Jiao Tong University and Y.L. Chen of Shanghai University (Peoples' Republic of China) show that while none of the established extraction dn separation techniques (distillation, solvent extraction, adsorption, ion exchange and membranes) are suitable for efficiently separating carboxylic acid mixtures such as acetic acid from acrylic acid, a novel metalorganic precipitation process is practical and can help to achiefve a near-zero discharge level in the production of acrylic acid.
