Fig. 8. Isokinetic plots for the decarboxylation of a malonic and b oxalic acids. Activation data for acetic acid are plotted for spatial reference. Filled and partially filled symbols represent aqueous systems. Linear least-squares fits to acetic acid, acetate, and the combined remaining data are given by the dashed, dotted, and solid lines, respectively. Note that with the exception of Crossey s (1991) results, the data for malonic and oxalic acids would superimpose. The data are given in Table 1. The acids and sources are as follows A, malonic (Richardson and O Neal 1972) A, malonic (Hall 1949) O, oxalic (Richardson and O Neal 1972) , oxalic (Crossey 1991) O, oxalic (Dinglinger and Schroer 1937, 1938 Lutgert and Schroer 1940) oxalic vapor (Lutgert and Schroer 1940) 0, dideuterio-oxalic (Lutgert and Schroer 1940) 0, dideuterio-oxalic vapor (Lapidus et al. 1966a,b) C, dideuterio-oxalic in D2O (Lutgert and Schroer 1940) B, acetic (Bell et al. 1993) , sodium acetate (Bell et al. 1993) and gallic (Boles et al. 1988). A more detailed version of this plot appears in Bell et al. (1993)...

Advances in analytical procedures resulted in several reports on anthocyanins acy-lated with hydroxycinnamic acids (p-coumaric, caffeic, ferulic, sinapic, and 3,5-dihydroxycinnamic acids), hydroxybenzoic acids (p-hydroxybenzoic and gallic acids), and aliphatic acids (malonic, acetic, malic, oxalic, succinic and tartaric acids). However, not all of them were found in anthocyanins isolated from foods. Among the 44 fruits listed in Table 4.3.1, 15 presented acylated anthocyanins as did 12 of 13 vegetables shown in Table 4.3.3 and 2 of the 9 grains cited in Table 4.3.4. On the other hand, acylated anthocyanins were found in all grapes from Vitis species, although at different abundance levels, as can be seen in Table 4.3.2. A higher... 

Methanol, ethanol and 3-methylbutanol [1], acetaldehyde, trichloroacetaldehyde [2] and acetone [3] all ignite in contact with gaseous fluorine. Lactic acid, benzoic acid and salicylic acid ignite, while gallic acid becomes incandescent. Ethyl acetate and methyl borate ignite in fluorine [2],... 

The measurements prove that the wines contain gallic acid, caffeic acid, apigenin, kaempferol, p-coumaric acid and naringenin. According to the mathematical statistical calculations the best mobile phase consisted of benzene-ethyl acetate-formic acid (30 15 5, v/v) [138],...

Bismuth subgallate [12552-60-2] (basic bismuth gallate), Dermatol, is a bright yellow powder that can be prepared by the interaction of bismuth nitrate and gallic acid in an acetic acid medium. It has been employed as a dusting powder in some skin disorders and as an ingredient of suppositories for the treatment of hemorrhoids (183,185). It has been taken orally for many years by colostomy patients in order to control fecal odors, but the dmg may cause serious neurological problems (186).

The ferric salts of benzoic, succinic, hydroferrocyanic, gallic and tannic acids are sparingly soluble in cold water, while basic ferric salts of formic and acetic acids formed on boiling are also sparingly soluble. Solutions of ferric thiocyanate and salicylate exhibit characteristic colorations.

There are many organic acids that can be produced by microbial or biochemical means. However, at present, only acetic acid (as vinegar), citric acid, itaconic acid, gluconic acid, 2-keto-gulonic acid, and lactic acid are produced industrially by fermentation. Other organic acids, such as fumaric, gallic, malic, and tartaric acids, once produced by fermentation or enzyme processes, are now produced commercially, predominantly by the more economic means of chemical synthesis.
