DOCUMENT TYPE: Patent CA Section: 16 (Fermentation and Bioindustrial Chemistry) Diglycolic acid (I) [110-99-6] and b-hydroxyethoxyacetic acid (II) [13382-47-3] are produced from diethyleneglycol (III) [111-46-6] by Candida, Torulopsis, Rhodotorula, Hansenula, Debaryomyces, Cryptococcus, or Pichia. Thus, Candida albicans IFO 0601 was cultured with shaking at 30° for 7 days in a medium (pH 7.0) contg. glycerol 10, (NH4)2SO4 4, KH2PO4 1, K2HPO4 1, MgSO4.7H2O 0.5, NaCl 0.1, CaCl2.2H2O 0.1, yeast ext. 1 g/L, 1 mL of a mineral soln., and 2 g III/10 mL. The prodn. of I and II was 1.0 and 0.5 g/L, resp.

Further relaxation kinetic investigations of iron(III) chelation

Further relaxation kinetic investigations of iron(III) chelation. Data for diglycolic, tartaric, and citric acids. Cavasino, F. Paolo; Di Dio, Emanuele; Sbriziolo, Carmelo (Ist. Chim. Fis., Univ. Palermo, Palermo 90123, Italy). 77-92-9 and 110-99-6 are cas registry numbers. These chemicals are also mentioned in this article. Int. J. Chem. Kinet., 16(3), 221-30 (English) 1984. CODEN: IJCKBO. ISSN: 0538-8066. DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) Section cross-reference(s): 78 The kinetics of the reactions of Fe(III) with diglycolic, tartaric, and citric acids were studied in aq. acid solns. by the temp.-jump method at 25.0° and ionic strengths 1.0 (for tartaric and citric acids) and 0.50 mol/dm3 (for diglycolic acid). Fe(III) monochelate formation occurs by the same reaction mechanism for all 3 ligands examd.; only pathways involving the FeOH2+ ion contribute to the chelation process. The reacting species for citric acid is the undissocd. ligand. For tartaric and diglycolic acids both the neutral ligands and the corresponding monoanions react significantly under the exptl. conditions used. Kinetic evidence for the contribution of intermediate steps to the limiting rate in the overall chelate-formation process was obtained and discussed. .
