| Abstract: | The chlorination synthesis of 4-(2-methyl-4-chlorophenoxy) butanoic acid from
4-(2-methylphenoxy) butanoic acid in aqueous phase using NaClO as chlorinating agent and in the
presence of catalysts is described. The catalyst has high selectivity and the whole process is
environmentally acceptable. This process can also be applied to the synthesis of other
2-methyl-4-chlorophenoxy based carboxylic acid. |
