In organic synthesis.

The mixture of trimethylamine, diiodomethane, dioxane and absolute ethanol was placed in the dark to react at room temperature for 100 h, the resulting crystals were collected by filtration, washed with ethanol and ether in turn, and dried under vacuum at 70 °C to obtain iodomethyl trimethylMethylammonium iodide. It was heated with sulfolane and kept at 160 °C for 12 min. The precipitated crystals were collected by filtration, washed with carbon tetrachloride, and vacuum dried at 50 °C to obtain N,N-DiMethylMethyleneaMMoniuM Iodide.
