The present study describes the effect of NCO/OH and triol/diol ratios on the mechanical properties of Nitro functionalized Hydroxyl-terminated polybutadiene (Nitro-HTPB) elastomers. The progress of the cure reaction of Nitro-HTPB and toluene diisocyanate (TDI) is evaluated by following up the variations in the IR absorption bands of the NCO stretching and the CO ...

The asymmetric nitro-Mannich reaction of N-phosphoryl imines with α-substituted nitroacetates was performed by using cinchona alkaloid thioureas as organocatalysts in toluene at -20 °C. The present method was highly tolerable to functionalized N-phosphoryl imines and provided a reliable synthetic route to obtain the corresponding β-nitro ethylphosphoramidates with adjacent quaternary and tertia...

The title compound, C(7)H(3)Cl(2)NO(4), was prepared by the reaction of 2,4-dichloro-6-nitro-toluene with 20% HNO(3) solution at 430 K. The carboxyl and nitro groups are twisted by 82.82 (12) and 11.9 (2)°, respectively, with respect to the benzene ring. The crystal structure is stabilized by O-H⋯O hydrogen bonding between carboxyl groups and weak C-H⋯O hydrogen bonding between the nitro group ...

In the title compound, C(14)H(11)Br(2)NO(4), the whole mol-ecule is disordered over two positions with a refined occupancy ratio of 0.539 (9):0.461 (9). The 2-nitro-furan and toluene groups are approximately planar, with maximum deviations of 0.176 (11) and 0.121 (14) Å, respectively, in the major component and 0.208 (11) and 0.30 (17) Å in the minor component. The dihedral angles between the 2...

A kinetic mechanism to predict secondary organic aerosol (SOA) formation from the photo-oxidation of toluene was developed. Aerosol phase chemistry that includes nucleation, gas–particle partitioning and particle-phase reactions as well as the gas-phase chemistry of toluene and its degradation products were represented. The mechanism was evaluated against experimental data obtained from the Uni...
