Maleic anhydride is prepared commercially by theoxidation of benzene or by the reaction of butane with oxygen in thepresence of a vanadium catalyst. 3.6 Purification Methods Crystallise the acid from acetone/pet ether (b 60-80o) or hot water. Dry it at 100o. [Beilstein 2 H 748, 2 I ...
the environment through various waste streams(SRC). Maleic acid is released directly to the environment in motor vehicle exhaust(3,4) and as a component of tobacco smoke(5). Maleic acid may be formed in the atmosphere via hydrolysis of anthropogenic releases or formation of maleic anhydride(6)...
Styrene–maleic acid (SMA) is the hydrolyzed form of the styrene–maleic anhydride (SMAnh) copolymer, which is synthesized by the copolymerization of styrene and maleic anhydride monomers (Fig.2, Reaction 1). Both forms of the polymer are widely used in industry and they have many different ...
Structural investigations on maleic anhydride (MAn) copolymers with ethene, propene and styrene, their products of hydrolysis, and their methyl half-esters by means of 13 C NMR spectroscopy are presented. The spectra of 2,3-diethylsuccinic acid and its anhydrides in the erythro - and threo -...
To address this adhesion problem, some studies were performed that opted for treating wood flour particles with NaOH solution [11,12] or coating the wood flour particles with stearic acid [13,14] and other focused on using the Maleic anhydride (MA) functionalized polymers for the production of...
forming a thin layer by coating a coating solution including a polyimide-based polymer end-capped with maleic acid anhydride, having a heteroaromatic pendant group including a heteroatom in its polyimide major chain, a photoinitiator and a crosslinking agent on a substrate, and drying the substrate...
A method of producing high molecular weight polysuccinimide and high molecular weight polyaspartic acid. Reacting maleic anhydride with ammonia and further reacting with polymerized polysuccinimide. Hydrolyzing the resultant product to form polyaspartic acid. ...
anhydride and then, after separating the condensate, scrubbing the gas stream with water. The resulting aqueous mixture of maleic anhydride is dehydrated by azeotropic distillation with xylene. This recovery process has the drawback of converting a fair amount of maleic anhydride into fumaric acid, ...
While onium ion intercalation is preferred, it should be understood that onium ion intercalation also is not necessary in accordance with the present invention when a relatively small amount of maleic anhydride-modified polyolefin, e.g., 0.2% to 10%, based on the total weight of polyolefin and...
