| Abstract: | The catalytic action on ferric chloride in the esterifying reaction of chloroacetic acid and alcohols has been studied. The results show that catalytic activity of ferric chloride is good. The percentage esterification of alcohols can be over 70% and vary in the order: higher alcohol>lower alcohol and primary alcohol>secondary alcohol>tertiary alcohol. The activation energy of esterifying reaction has been calculated. The catalytic mechanism of ferric chloride is discussed. |
