摘要: Publisher Summary Qualitative determination of itaconic acid can be based on its physical and physical-chemical data as well quantitative catalytic hydrogenation shaking in aqueous solution with a palladiumcharcoal catalyst. Methylsuccinic acid, which is obtained product, isolated by ether extraction characterized melting point, 111 to 112 °. Quantitative bromine absorption. A selective absorption the ensured buffering at pH 1.2. Itaconic also usually determined directly fermentation solution, after mycelium has been removed filtration or centrifugation. If buffered against it must slightly acidified before added. stored refrigerator temperature reagent raised room (20 °) use. Biosynthetic method for preparation involves glucose sucrose Aspergillus terreus aerated, media. The products are: mold mycelium, carbon dioxide, (55 59% weight sugar consumed), trace malic acid. latter easily separated from because greater solubility.
