Formaltal

It is mainly used for the production of anion exchange resins, and is also used as solvents and special fuels. Its dissolution ability is stronger than that of diethyl ether and acetone, and methanol and azeotropic mixture can dissolve nitrocellulose with high nitrogen content . However, because its vapor is highly anesthetized, it is not suitable for use as a general solvent, and is usually used as a special sonic solvent. It is also used in the production of spices and the production of artificial resins, which are used as a reaction medium for the Grija reaction and Rapa (synthesis) reaction.
