Benzoyl chloride and methanol reaction. When -COCl group is combined with a benzene group, we call it benzoyl chloride. When methanol is added to the ... The method being described here is for making FAMEs biodiesel. The reaction is called transesterification, and the process takes place in four steps. The first step is to mix the alcohol for reaction with the catalyst, typically a strong base such as NaOH or KOH. The alcohol/catalyst is then reacted with the fatty acid so … See more Once the catalyst is prepared, the triglyceride wiil react with 3 mols of methanol, so excess methanol has to be used in the reaction to ensure complete reaction.
