Production methods and others:

 Under nitrogen, let pure ethyl ether react with crushed lithium wire to a temperature of -10℃, start stirring, and dropwise add the ethyl ether solution of bromobutane. After dropping is completed, slowly warm to 0-10℃, react for 1-2 hours, filter to obtain the ethyl lithium ethyl ether solution (commercial product), with a yield of 80-90%.
