Maleic anhydride is also a precursor to compounds used for water treatment detergents, insecticides and fungicides, pharmaceuticals, and other copolymers. IGPL produces Maleic Anhydride through wash water generated out of the production process of Pthalic Anhydride.
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.

Maleic anhydride as well as maleic and fumaric acids were first prepared in the 1830s. However, commercial manufacture did not begin until a century later. In 1933, the National Aniline and Chemical Co., Inc., used a process for producing maleic anhydride based on benzene oxidation using a vanadium oxide catalyst.
We investigated the synthesis of maleic anhydride by oxidehydration of a bio‐alcohol, 1‐butanol, as a possible alternative to the classical process of n ‐butane oxidation.A vanadyl pyrophosphate catalyst was used to explore the one‐pot reaction, which involved two sequential steps: 1) 1‐butanol dehydration to 1‐butene, catalysed by acid sites, and 2) the oxidation of butenes to ...

At room temperature maleic anhydride is a white crystalline solid with an acrid odor. Maleic anhydride is soluble in water, acetone, ethyl acetate, chloroform, and benzene. Vapor pressure is 25 Pa at 25C. In presence ° of water maleic anhydride hydrolyzes to maleic acid. Phthalic anhydride (C. 8 H 4 O 3), CAS 85-44-9 . Synonyms: 1,2 ...
Jun 28, 2020· Maleic anhydride is a convenient and environmentally friendly material. A variety of dedicatedly‐designed PMAC matrices can be tuned through anhydride group and double bond in MA, which exhibited superior electrochemical properties, such as high ionic conductivity, high lithium‐ion transference and good interfacial compatibility with anodes ...
Maleic anhydride (MA) is derived from butane in the US. In Europe and Asia, MA is derived predominantly from butane units, although a small amount is produced by benzene units. ... The butane-based process is considered to have superior economics and is the preferred route by most producers. However, a small amount is produced by the benzene route.
Feb 02, 2020· 2.2. Selection of process routes: Maleic anhydride production. MAN is a relevant chemical good to nowadays society since it is generally used as an intermediate for the production of unsaturated polyester resins, polymers, vernices and paints, among other products.

Scientific Design's technology offers a safe and highly efficient means of converting n-butane to maleic anhydride (MAN). The plant can be customized to produce a pure, final product in solid form or a high quality molten intermediate which can be used to feed MAN derivative plants such as 1,4-butanediol (BDO), tetrahydrofuran (THF), and γ-butyrolactone (GBL).
Maleic anhydride is used in the formulation of resins. Exposure to maleic anhydride may occur from accidental releases to the environment or in workplaces where it is produced or used. Acute (short-term) inhalation exposure of humans to maleic anhydride has been observed to cause irritation of the respiratory tract and eye irritation.
The aim of this project was to design a production plant capable of manufacturing 40,000 tons/year maleic anhydride from benzene feedstock. The process was simulated using Aspen Hysys version 10 ...
