Uses:
Maleic anhydride is mainly used for the production of unsaturated polyester, then used in medicine, pesticides, paints, oil additives, and various additives and fine chemicals. For this year, a large number of 1.4-butanediol, tetrahydrofuran, y-propyl, and many small manufacturing hydrogenated anhydride.
