Preparation method：

To produce this substance, a series of chemical reactions take place. Initially, ethylene glycol monomethyl ether is combined with sodium metal and chloromethane. The mixture is then heated and stirred until the sodium metal reacts completely. Subsequently, the temperature is lowered to 45 °C, and chloromethane is introduced into the reaction. After completion, the mixture is subjected to a process called fractionation, and a specific fraction with a boiling point range of 84-85.5℃ is collected to obtain the final product. This process ensures the production of the desired substance with the selected properties.
