Dec 01, 2015· In addition, maleic anhydride can be used as a raw material in the production of 1,4-butanediol (BDO), gamma-butyrolactone (GBL) and tetrahydrofuran (THF). BDO has been one of the world's fastest growing chemicals in recent years. The process. The following paragraphs, along with Figure 1, describe a process for producing MAN from n-butane.
Maleic anhydride is used in the production of unsaturated polyester resin as well as in the manufacture of pharmaceutics and agricultural products. Currently, MA is not produced in Russia. According to customs statistics, the import of maleic anhydride is about 5-6 000 tons per year.
The maleic anhydride (MAN) is then separated from the rich solvent and the lean solvent is recycled. In the end, the economics of maleic anhydride (MAN) production are presented for an integrated plant ...

At purities greater than 60%, the maleic acid begins to separate from the solution. 2.3.2 Reaction Train . Maleic acid is hydrogenated to THF via a series of simultaneous reactions in a back-mix tank reactor. The reactions are a series of hydrogenations in which bonds are broken in the reacting maleic acid and chemical intermediates.
