The asymmetric unit of the title co-crystal, C12H9N5O·0.5C6H10O4, consists of one mol-ecule of N (6)-benzoyl-adenine (BA) and one half-mol-ecule of adipic acid (AA), the other half being generated by inversion symmetry. The dihedral angle between the adenine and phenyl ring planes is 26.71 (7)°. The N (6)-benzoyl-adenine mol-ecule crystallizes in the N(7)-H tautomeric form with three non-proton...

The evidence concerning the utilization of dibasic fatty acids in the animal organism has been reviewed by Dakin (3) and more recently by Flaschentrager (4). Oxalic acid is burned to a limited extent, and in large amounts is toxic. Malonic and succinic acids are utilized, and glutaric acid is completely oxidized in the dog (3), but is nephrotoxic to the rabbit, while the higher acids affect the...

A water-soluble self-assembly has been formed by associating adipic acid molecules onto the surface of the third generation poly(propyleneimine) dendrimer and this system has been used to encapsulate fluorescein.

The biodegradability of three aliphatic adipic acid diesters and a 1,3-butylene glycol adipic acid polyester was determined in acclimated, activated sludge systems. Rapid primary biodegradation from 67 to 99+% was observed at 3- and 13-mg/liter feed levels for di-n-hexyl adipate, di(2-ethylhexyl) adipate, and di(heptyl, nonyl) adipate in 24 h. When acclimated, activated sludge microorganisms we...

This work is part of a study aiming to improve crystallization processes. The batch crystallization of adipic acid is chosen as a case study, a process in which the supersaturation necessary for the crystals to appear and grow is generated by the cooling of the solution. This part of the study involves the process modeling and an analysis of the influence of the process variables on the final c...
