Itaconic acid[97-65-4] (methylenebutanedioic acid, methylenesuccinic acid) is a crystalline, high melting acid (mp = 167—168) produced commercially by fermentation of carbohydrates (1—4). Itaconic acid is produced in the broth from citric acid (qv). Isolated from the pyrolysis products of citric acid in 1836, this a-substituted acrylic acid received its name by rearrangement of aconidc, the acid from which it is formed by decarboxylation.

In 2003, Goti et al. [13] described the total synthesis of hyacinthacine A2 through cycloaddition between acrylic acid derivatives and a carbohydrate-derived nitrone 31, which was obtained firom L-xylose or D-arabinose (Scheme 3). [Pg.381]

The second zone also contains carbohydrate opportunities, exemplified by, e.g., glycolic [73,104], pyruvic [105], lactic [74], and acrylic acids as well as glyoxal, glycolaldehyde [72, 106], acetic acid [71], erythritol [70], and y-valerolactone [47, 77]. A petrochemical route to these chemicals could be derived (e.g., the route to lactic acid via hydrolysis of acrylonitrile [107]), but in general, the carbohydrate route is likely to be cost-competitive. Glyoxal, acetic acid, and... [Pg.17]

Lactic acid (LA) is one of the top carbohydrate-derived chemicals and it was recently included in BozeU and Petersen s revised selecticai of the top ten sugar-based chemicals [10, 24]. The conversion of carbohydrates into LA via anaerobic fermentation has been known for ages [25]. The first industrial fermentation was developed by A. Boehringer in 1895 and at the present time the global installed production capacity is estimated at 0.5 Mton year [10, 26, 27]. The current fermentation process and its issues will be critically discussed in Sect. 3 in light of the major application of LA today, i.e., as monomer for commercial bioplastic PLA [28]. Besides being used for polyester synthesis, LA is seriously considered as a platform chemical for the synthesis of a diverse range of chemicals such as pyruvic acid, 2,3-pentanedione, and acrylic acid [10, 29].

Water-soluble polymeric compounds. These can be natural or modified natural products such as gelatine, starch, or carbohydrate derivatives such as methyl cellulose, hydroxyalkyl cellulose, or salts of carboxymethyl cellulose. Synthetic polymers such as poly(vinyl alcohol), partially hydrolyzed poly(vinyl acetate), sodium salts of poly(acrylic acids), methacrylic acids, and copolymers thereof are widely used in quantities between 0.1 and 1% related to the aqueous phase.
