6-Chloro-2-hydroxybenzoic acid

However, under some circumstances, the rate is not only leveled but it is also inhibited as the substrate concentration increases. In a comprehensive study on 3-chloro-4-hydroxybenzoic acid and chlorophenols, Cunningham and colleagues [35] deduced that the rate can be strongly inhibited in consequence of (1) chemisorption-induced depletions of surface —OH groups, (2) adsorbate-enhanced hole-electron recombination on the TiO2 surfaces, (3) mass transport limitations within the TiOz particle aggregates. They reported that, depending on...

A mixture of 4-chloro-2-hydroxybenzoic acid (5 g), Cs2C03 (17.5 g), and 2-chloro-M ALdimethylacetamide (6.6 g) was stirred 3 hours at 70°C, then diluted with water and EtOAc. The organic phase was separated, dried, and concentrated to a gum. The gum was purified by chromatography using EtOAc/methyl alcohol, 9 1, and 8.0 g solid product isolated, mp = 140-141°C.
