photoreactor using solar radiation. The effect of various parameters such as pH, initial concentration of pollutant, catalyst dose, oxidant, and time variation were studied. The determination of the best catalyst was studied amongst the four catalysts (TiO2, ZnO, PSA and SSA) .The kinetics of degradation of isooctane was also studied. The results showed that TiO2 was the best catalyst with a de...

The title compound, C(22)H(21)ClFNO(6), was synthesized by the 1,3-dipolar cyclo-addition reaction of dimethyl maleate, methyl 2-amino-2-phenyl-acetate and 2-chloro-4-fluoro-benzaldehyde. The pyrrolidine ring possesses an envelope conformation and the two benzene rings are oriented at a dihedral angle of 68.28 (7)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure...

Four new p-aminoacetophenonic acids, named (2E)-11-(4′-aminophenyl)-5,9dihydroxy-4,6,8-trimethyl-11-oxo-undec-2-enoic acid (1), 9-(4′-aminophenyl)-3,7dihydroxy-2,4,6-trimethyl-9-oxo-nonoic acid (2), (2E)-11-(4′-aminophenyl)-5,9-O-cyclo4,6,8-trimethyl-11-oxo-undec-2-enoic acid (3) and 9-(4′-aminophenyl)-3,7-O-cyclo-2,4,6trimethyl-9-oxo-nonoic acid (4), were isolated from an endophyte Streptomyce...

The title compound, [Co(C(8)H(4)O(4))(C(13)H(14)N(2))(2)(H(2)O)(2)](n), was obtained by the reaction of CoCl(2), 4,4'-trimethyl-enedipyridine and terephthalic acid in a 1:1:1 ratio. The octa-hedrally coordinated cobalt ions are bridged by 4,4'-trimethyl-enedipyridine ligands, generating a chain. These chains are further linked by O-H⋯O and O-H⋯N hydrogen bonds, giving a three-dimensional network.

The conversion of 6-N-[Me-(14)C]trimethyl-lysine into carnitine and 4-N-trimethylaminobutyrate (butyrobetaine) was demonstrated in rats kept on a lysine-deficient diet. After the rats were given [(14)C]trimethyl-lysine for 4 days, a total of 17% of the injected label was recovered as carnitine from carcass and urine extracts. Another 8% of the trimethyl-lysine label was converted into 4-N-trime...
