The asymmetric unit of the title hydrated co-crystal, 2C19H13N5·C6H10O4·4H2O, consists of one 2,6-bis-(1H-benzimidazol-2-yl)pyridine mol-ecule, half of an adipic acid mol-ecule (bis-ected by an inversion center) and two water solvates. In the crystal, N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.769 (2) and 3.731 (2) Å] form a three-dimensional su...

Synthesis of adipic acid by catalytic oxidation of cyclohexanone with 30% hydrogen peroxide in the presence of sodium tungstate catalyst can be well performed under reflux temperature. The adipic acid isolated yield reaches to 82.1%, and the purity of the product is also very high. The catalytic oxidation reaction takes place without any organic solvent and phase-transfer agent. The effects ove...

Chiral C(2)-symmetric 3,4-bis-silyl-substituted adipic acid derivatives have been synthesised by a Mg/trimethylsilyl chloride-mediated intramolecular reductive coupling of symmetrical disiloxanes of beta-silylacrylic acid N-oxazolidinone derivatives. Efficient and short syntheses of enantiomerically pure enantiomers of 2,6-dioxabicyclo[3.3.0]octane-3,7-dione have been achieved from the bis-sily...

The asymmetric unit of the title co-crystal, 2CH(4)N(2)O·C(6)H(10)O(4), contains two urea mol-ecules and two half-mol-ecules of adipic acid; the latter are completed by crystallographic inversion symmetry. The crystal packing is stabilized by O-H⋯O and N-H⋯O hydrogen bonds, generating a chain along [110]. Additional weak inter-chain O-H⋯O and N-H⋯O inter-molecular inter-actions lead to the form...

A novel method to characterize the organic composition of aerosol particles has been developed. The method is based on organic vapor interaction with aerosol particles and it has been named an Organic Tandem Differential Mobility Analyzer (OTDMA). The OTDMA method has been tested for inorganic (sodium chloride and ammonium sulfate) and organic (citric acid and adipic acid) particles. Growth cur...

A limited life cycle assessment (LCA) was performed on a combined biological and chemical process for the production of adipic acid, which was compared to the traditional petrochemical process. The LCA comprises the biological conversion of the aromatic feedstocks benzoic acid, impure aromatics, toluene, or phenol from lignin to cis, cis-muconic acid, which is subsequently converted to adipic a...
