-
Page/Page column 20-21, (2010/02/13)
PROBLEM TO BE SOLVED: To provide a low-hue polycarboxylic acid mixture of high thermal stability, to provide a method for producing the low-hue polycarboxylic acid mixture in high yield with no need of any special equipment and process, and to provide a curable composition comprising a compound having in the molecule two or more epoxy groups and a curing agent ccomprising the low-hue polycarboxylic acid mixture. SOLUTION: The low-hue polycarboxylic acid mixture contains ≥80 mass% of 1,3,6-hexanetricarboxylic acid and also contains 10-5,000 mass ppm of an inorganic salt. For this polycarboxylic acid mixture, the psychometric lightness L-value of a solution made by dissolving 1.00 g of the mixture in 5.0 mL dimethylformamide is ≥98, the (a)-value of the chromanetics index of the solution is -2.0 to 2.0, the (b)-value is -2.0 to 3.0.

Two fungal strains, TG-1 and TG-2, utilizing triacrylonitrile (1,3,6-hexanetricarbonitrile, TAN) as nitrogen source, were isolated from soil and identified as Fusarium merismoides Corda var. merismoides and Fusarium solani (Mart.) Sacc. emend.Snyder et Hansen var. solani, respectively.F. merismoides TG-1 could utilize TAN, adiponitrile, glutaronitrile, diacrylonitrile and 2,4-dicyano-1-butene as nitrogen source.Conditions for cultivation of the strain were studied.Degradation products of TAN were isolated from the culture broth and determined to be a mixture of 5,7-dicyanoheptanoic acid (62percent) and 4,7-dicyanoheptanoic acid (38percent).A mixture of 5,7-dicyanoheptanoic acid (11percent) and 4,7-dicyanoheptanoic acid (89percent) was also obtained from the culture broth of F. solani TG-2.
