Patent number: 10155714Abstract: The present invention pertains to a process for the purification of a feed comprising monochloroacetic acid and dichloroacetic acid wherein the feed is subjected to a catalytic hydrodechlorination step by contacting it with a source of hydrogen to convert dichloroacetic acid into monochloroacetic acid in the presence of a solid heterogeneous hydrogenation catalyst comprising a Group VIII noble metal on a carrier under hydrodechlorination conditions, wherein the reaction is carried out in the presence of a catalyst enhancer which comprises a salt of a metal selected from the group of non-noble metals of Group VIII, Group VIB, Group VIIB, and Group IIB. It was found that the presence of a catalyst enhancer leads to reduced deactivation of the catalyst and/or increased activity of the spent catalyst. This allows longer production cycles, less downtime, and lower formation of side products.Type: GrantFiled: March 14, 2016Date of Patent: December 18, 2018Assignee: AKZO NOBEL CHEMICALS INTERNATIONAL B.V.Inventors: Lars Magnus Tollin, Melle Rinze Nieuwhof, Arie Grootenboer, Jacobus Theodorus Josef Aaldering, Henricus Johannes Marinus Petrus Van Hal, Matheus Theodorus De Groot
