Phosphorous acid reacts with acetic anhydride to give almost quantitative yields of poly(ethane, l-hydroxy, l,l-diphosphonates); hydrolysis studies suggest the presence of the interlinked units f o# o ro, i,o , -X = H or Ac in the product.
The esterification process of ethenyl benzene and its derivative compounds @-methyl, p-methoxy, p-chloro, m-methyl, m-nitro and m-chloro, respectively) was carried out with acetic acid and using perchloric acid as a catalyst. From the effects of the variables studied it could be concluded that: the
