Abstract
The hydrogenation of 2-amino-4-methyl-6-nitrophenol, 2-chloro-4-nitrophenylformamide, 4рnitro-m-xylene, 2-nitro-m-xylene, o-bromonitrobenzene, o-nitroethylbenzene, p-nitroaniline, 1-(3-nitrophenyl)-3-(4-nitrophenyl)urea, 1-(2-methoxy-4-nitrophenyl)-3-(2-methoxy-5-nitrophenyl)urea, pрnitrophenol, o-nitrophenol, 5-(3-nitrophenyl)-2,3,7,8,12,18-hexamethyl-13,17-di-n-butylporphine, 5р(4-nitrophenyl)-2,3,7,8,12,18-hexamethyl-13,17-di-n-butylporphine, 5,15-bis(4-nitrophenyl)-3,7,13,17-tetramethyl-2,8,12,18-tetra-n-butylporphine and 5,10,15,20-tetrakis(3-nitrophenyl)porphine in the presence of palladium-containing aminated activated carbon has been studied under mild conditions (solvent, ethanol; T = 25–45°C; and ({{P}_{{{{{text{H}}}_{2}}}}}) = 1 atm). It has been found that strong substituents of the first kind in aromatic nitro compounds accelerate the hydrogenation of the nitro group and the hydrogenation of porphyrins containing nitro groups on the periphery of a macrocyclic ring afford the corresponding amino derivatives.
对硝基苯胺、1-(3-硝基苯基)-3-(4-硝基苯基)脲、1-(2-甲氧基-4-硝基苯基)-3-(2-甲氧基-5-硝基苯基)脲、对硝基苯酚、邻硝基苯酚、5-(3-硝基苯基)-2,3,7,8,12、18-hexamethyl-13,17-di-n-butylporphine, 5р(4-nitrophenyl)-2,3,7,8,12,18-hexamethyl-13,17-di-n-butylporphine, 5,15-bis(4-nitrophenyl)-3,7,13,17-tetramethyl-2,8,12,18-tetra-n-butylporphine and 5,在温和的条件下（溶剂为乙醇；T = 25-45°C; and ({{P}_{{{{{text{H}}}_{2}}}}}) = 1 atm）。研究发现，芳香族硝基化合物中的第一类强取代基会加速硝基的氢化，而在大环外围含有硝基的卟啉的氢化反应会产生相应的氨基衍生物。

Abstract
The effect of inorganic salts and CuO nanoparticles on the dynamic viscosity of a lamellar liquid crystalline mesophase in the lecithin–avocado oil–tea tree oil–water system was studied using rotational viscometry in a range of shear rates from 0.01 to 1.0 s–1. It was found that the viscosity of liquid crystals increased by a factor of 1.2–6.25 upon the introduction of aqueous solutions of NaCl, CaCl2, and CuCl2 with a concentration of 0.1 mol/L or higher. The introduction of spherically shaped CuO nanoparticles with a size of 92 ± 3 nm at a concentration of 0.3 wt % increased the viscosity by a factor of 1.3.
