Mono and polynuclear silver(I) complexes with thiosaccharine and triphenylphosphine or 2,2?-bipyridine. Synthesis, spectroscopic and structural characterization

Reaction of Ag6(tsac)6 (tsac- = thiosaccharinate anion) with PPh3 and 2,2?-bipyridine (bipy) ligands give rise to three new silver-thiosaccharinate complexes, [Ag(tsac)(PPh3)3], [Ag4(tsac)4(PPh3)3], and [Ag2(tsac)2(bipy)2]. Their crystal structures established by single-crystal X-ray diffraction and IR spectroscopic characterizations are reported here.

It crystallizes in the monoclinic space group P21/a with Z = 4. The thiosaccharinate moiety is planar and shows small but significant modifications in the bonding of the thioamide functional group as compared with the protonated neutral molecule. The ionic crystal is further stabilized by an extensive H-bonding network, which links the anions and cations into an infinite three-dimensional supramolecular assembly. The FTIR spectrum of the compound is briefly discussed in comparison with those of the neutral constituent molecules.

Characterization of Aroma Compounds in Two Meat Flavorings Prepared from Thermal Reaction of Enzymatic Hydrolysates of Black Pig and Common White Pig Meat Proteinss with Oxidized Lard

Meat flavorings were prepared by thermal reactions of enzymatic hydrolysates of black pig and common white pig (large white) meat proteins with oxidized lard. The volatile compounds of the two meat flavorings were analyzed by solvent assistant flavor distillation (SAFE) combined with gas chromatography and mass spectrometry (GC-MS). Based on retention indices and mass spectra, a total of 123 volatile compounds, including sulfur-containing compounds, nitrogencontaining heterocycles, oxygen-containing heterocycles, aldehydes, ketones, alcohols, acids, esters and hydrocarbons, were identified. In comparison, the white pig meat-derived flavoring had a greater percentage (relative to the total peak area) of alkyl furanes, aliphatic aldehydes and acids while the black pig meat-derived flavoring had a greater percentage of sulfur-containing compounds, nitrogen-containing heterocycles, and esters. However, their relative contents of ketones and alcohols were similar. Furthermore, by gas chromatography-olfactometry (GC-O), a total of 31 odor-active compounds were identified through comparison of their retention indices and odor characteristics with those of authentic standards. Among them, 28 compounds were common to two meat flavorings, and in particular dimethyltrisulfide, furfuryl mercaptan, 3-ethyl-2,5-dimethylpyrazine, 3-(methylthio) propanal,2-ethylthiophene,(E,E)-2,4-decadienal,(E)-2-decenal,(E)-2-nonenal,1-octen-3-ol and 3-hydroxy-2-butanone had high flavor dilution (FD) factors. However, the number of compounds with high FD values was greater in the black pig meat-derived flavoring than in the white pig meat-derived flavoring. Additionally, the spider-web plots for the potent odor-active compounds revealed that the black pig meat-derived flavoring had higher scores for meaty and fatty odors than the black pig meat-derived flavoring, which could explain why the black pig meat-derived flavoring had stronger meaty aroma than the black pig meat-derived flavoring.

Complete study of the pyrolysis and gasification of scrap tires in a pilot plant reactor

The pyrolysis and gasification of tires was investigated in a pilot plant reactor provided with a system for condensation of semivolatile matter. The study comprised experiments at 450, 750, and 1000C both in nitrogen and 10% oxygen atmospheres. In the gas phase, only methane and benzene yields increased with temperature until 1000C. In the liquids, the main components were styrene, limonene, and isoprene. The solid fraction (including soot) increased with temperature. Zinc content of the char decreased with increasing temperature. Analysis of the surface area of the solids showed that the area was similar in all cases to that of a commercial carbon black. The higher surface of the soot with respect to the chars was observed. The results coincided with published findings, i.e., kinetic severity function values would produce 0.2% of methane at 450C and 4.5% at 750-1000C.
