Zhen, Zong-Yuan published the artcileDetermination of volatile flavor compounds in raw and treated duck meats of different body parts, SDS of cas: 1455-77-2, the main research area is volatile flavor compound body part duck meat; duck meat; gas chromatography-mass spectrometry (GC-MS); headspace solid-phase micro-extraction (SPME); volatile flavor substance.

The compounds in volatile flavor substances in duck meats of three different body parts (breast, leg, and wing) were extracted by headspace solid-phase micro-extraction and determined by gas chromatog.-mass spectrometry. A total of 16 main volatile compounds including 4 hydrocarbons, 4 alcs., 2 acids, 3 aldehydes, and 3 others (N-containing, S-containing) were identified in raw duck meats from three different body parts. The hydrocarbon compounds account for more than 50% of all volatile substances in all three body parts. And the percentage of hydrocarbon compounds in raw duck breast meat reaches 82.76%. A total of 81 volatile compounds including 15 hydrocarbons, 10 alcs., 7 acids, 12 aldehydes, 4 esters, 19 S-containing and N-containing compounds, and 14 others were isolated and identified in 1 h-marinated and cooked duck meats. A total of 101 kinds of volatile flavor compounds including 13 hydrocarbons, 14 alc., 7 acids, 8 aldehydes, 12 esters, 23 S-containing and N-containing compounds, and 24 others were detected in 3 h-marinated duck meats of the three body parts. It was proved in this study that under the same conditions, the volatile compounds in duck legs are more than those in duck breasts and wings, and the types of volatile flavor substances increase significantly in duck meats after cooked. Practical applications Prepared and cooked duck meat, especially wings and legs are popular food in China. The results suggest that Pickling makes duck meat more flavory while proper pickling time is less than 3 h. Duck wings are better for marinating and cooking compared with duck breasts and legs. The acceptance study of duck meat from different body parts and the anal. of volatile flavor compounds are beneficial for optimizing utilization of whole parts of duck meat.

Studying of charge-transfer (CT) and proton transfer interactions is essential due to their important role in many biol. field and industrial applications. The current work will add more information’s about the nature of interaction between 3,5-diamino-1,2,4-triazole (DAT) and 6-methyl-1,3,5-triazine-2,4-diamine (MTDA) with 3,6-dichloro-2,5-dihydroxy-p-benzoquinone (chloranilic acid CLA) which was studied spectrophotometrically in Ethanol (EtOH) and Methanol (MeOH) solvents at different temperatures The mol. composition of the formed complexes was studied by applying continuous variation and spectrophotometric titration methods and found to be 1:1 charge transfer complex for both Complex (DAT:CLA) and (MTDA:CLA) which are produced. Min.-Maximum absorbance’s method has been applied to calculate the formation constant KCT and mol. extinction coefficient (ε); they recorded high values confirming high stability of the produced complexes. Oscillator strength (f), transition dipole moment (μ), ionization potential (IP) and dissociation energy (W) of the formed CT-complexes were also determined and evaluated; they showed solvent dependency. It is concluded that the formation constant (KCT) of the complexes is found to depend on the nature of both electron acceptor and donors and on the polarity of solvents.

Nayak, Amrita published the artcileAnhydrous vs Hydrated f-Element Acetate Polymers Dictated by the Stoichiometry of Protic Acidic/Basic Azole Mixtures, Synthetic Route of 1455-77-2, the main research area is cerium neodymium azole acetate anhydrous hydrated coordination polymer preparation; crystal mol structure cerium neodymium azole acetate coordination polymer.

Continuing authors investigations of ionic liquid (IL) based routes to a library of f-element/soft donor complexes which could be studied crystallog., they have explored the dissolution of f-element salts in protic imidazole-based ILs containing only soft donors at high temperatures to drive off volatiles, including water and carboxylic or mineral acids. Here they present their results, reacting acidic and basic azoles in 1:3 or 1:1 stoichiometric compositions at elevated temperature, followed by saturation with Nd(OAc)3·xH2O or Ce(OAc)3·xH2O, which led to 13 new metal-acetate polymeric complexes identified by single-crystal x-ray diffraction. Authors found that the diversity in coordination modes of the simple acetate ligand that interfere with substitution of the softer N donors led to several readily crystallizable complexes forming two distinct groups with respect to f-element interaction with the ionic liquid precursors. When the acidic/basic azole ratio was 1:3, acetate and a neutral basic azole were coordinated to the metal centers but no water, although in one case (2) water was observed in the secondary coordination sphere: [Ce(μ2-OAc)3(C1i.m.)]n (1, C1i.m. = 1-methylimidazole), [Nd(μ2-OAc)3(C1i.m.)]n·nH2O (2), [Ce(μ2-OAc)3(C2i.m.)]n (3, C2i.m. = 1-ethylimidazole), [Ln(μ2-OAc)3DMF]n (Ln = Nd (4), Ce (5); DMF was substituted for the azole mixture), and [Nd(μ2-OAc)3(C4i.m.)]n (6, C4i.m. = 1-butylimidazole). However, when the stoichiometric ratio was 1:1, water was always observed coordinated to the metal ions with the acidic azole included in the structure as a solvate or cocrystal, despite a higher reaction temperature: [Nd(μ2-OAc)3(OH2)]n·n(1,2,3-Taz) (7, 1,2,3-Taz = 1,2,3-triazole), [Ln(μ2-OAc)3(OH2)]n·n(4,5-DCim) (Ln = Nd (8), Ce (9), 4,5-DCim = 4,5-dicyanoimidazole), [Ln(μ2-OAc)3(OH2)]n·n(3,5-diNH2-1,2,4-Taz) (Ln = Nd (10), Ce (11), 3,5-diNH2-1,2,4-Taz = 3,5-diamino-1,2,4-triazole), [Ce(μ2-OAc)3(OH2)]n·n(3-NH2-1,2,4-Taz) (12, 3-NH2-1,2,4-Taz = 3-amino-1,2,4-triazole), and [Nd(μ2-OAc)3(OH2)]n·n(5-NH2-Tz) (13, 5-NH2-Tz = 5-aminotetrazole). All of the compounds retain the Ln:OAc- ratio of 1:3 and form 1D polymeric chains; however, they exhibit a variety of coordination modes affecting the degree of chain condensation. The isolation of both hydrated and anhydrous products revealed different abilities of the investigated soft N-donors to compete with O-donors finding their place in the coordination sphere of the lanthanide or in the crystal lattice.
