| Zusammenfassung: | The invention relates to a green chemical synthetic method for n-butyryl chloride, in particular to a chemical synthetic method for preparing n-butyryl chloride by utilizing the reaction between bis (trichloromethyl) carbonate and n-butyric acid. The method comprises the steps of: with n-butyric acid and bis (trichloromethyl) carbonate as the raw materials, reacting in organic solvent at the temperature of 50 DEG C to 100 DEG C for 1 to 10 hours under the action of an organic amine catalyst, and then distilling to obtain the n-butyryl chloride. The method provided by the invention has the advantages of advanced process route, reasonable process conditions, simplicity and safety in operation, high reaction yield rate, low production cost, and less 'three wastes' (waste gas, waste water and waste residues); and the method has greater implementation value and social and economical benefits. |
