Different imines were prepared.The reaction was carried out using different conditions,with aromatic aldehydes,aniline and with different energy sources.Yield,purity and experimental fusion point were calculated in each case,and they were compared to the ones found in literature.The importance of structural effects of aldehyde reacting with aniline was established as well as reaction conditions.The efficacy of the reaction can not be predicted,since each aldehyde has a different structure and therefore reacts differently.The main objective of this project is academic.A methodology to carry out a structured research(it is one of the levels of problem-based learning(ABP)),was implemented.Students work in pairs using Combinatorial Chemistry,and each pair does a different exercise on the same theoretical objective.Results from every team are discussed in a seminary where conclusions regarding which was the most efficient reaction are reached. 展开更多

Eight crosswords made in JClic were applied to twenty nine students from group 654, in area 2, at ENP (national preparatory school) No. 4 (a national public high school) in order to review Unit 2 and introduce the following Unit of Chemistry IV. Two surveys were applied in scholars in order to evaluate: the application of crosswords and of ICT (information and communications technology). The results show that students like ICT because it is a relaxing mechanism to learn, JClic games were also liked by the majority due to the team work, so it induces to considerable learning. 展开更多

Eu 3+ ions were incorporated in sol and gel by a sol gel processing using 3 glycidoxypropyltrimethoxysilane (CH 2OCHCH 2O(CH 2) 3Si(OCH 3) 3, GPTMS) and ethyl silicate (TEOS) as precursors. The basic chemical physical properties such as DTA curve, FT IR spectra and specific surface area were recorded. The characteristics of their optical spectra were measured and investigated. The results indicate that the emission intensity of Eu 3+ ion in ormocer is much higher and the global line width is wider than those in SiO 2 gel. The relationship between the composition and structure of gels and the fluorescence intensity and width were discussed. The obtained ormocer shows good mechanical strength, which can be cut and polished in machine without broken. 展开更多

The La^(3+)-loaded adsorbent was prepared by the reaction between La^(3+) and ethanolamine-modifying vegetable tannic extract, to treat F^--containing wastewater. The problems of heavy color caused by vegetable tannic extract and of turbidity caused by reaction between La^(3+) and F^- were solved. When other conditions were not changed, and pH, temperature, stirring time, and dose were changed respectively and the adsorbance was tested respectively. The results show that this adsorbent possesses high saturated adsorptive capacity (18.86 mg·g^(-1)) when pH is 5~6, T≤80 ℃, 0.2 g dosage, and 180 min agitating time, and the adsorbance reaches the highest (98.5%). The adsorbent can be easily regenerated with 0.5 mol·L^(-1) NaOH at pH 12. 展开更多

The properties of NTZF were estimated: density is 1.67 g/cm3, enthalpy of formation +415.41 kJ/mol and detonation velocity 8257.83 m/s. The main thermal properties of four compounds, DTZAF, HATZF, TAGATZF and MATZF, were analyzed by TG and DSC techniques and the results showed that their melting points are 251.9, 159.7, 205.4 and 211.4 ℃, respectively, and their first decomposition temperatures are 256.7, 258.6, 231.7 and 268.6℃, respectively. The fact that their decomposition temperatures were over 230 ℃ showed that they exhibit better thermal stability. 展开更多

Facile synthetic routes for the preparation of some new 4-amino-3,5-dinitropyridine derivatives have been revealed. Nitration of 2-chloropyridin-4-amine (1) as a starting material, in an unexpected one-step reaction, to give dinitrated derivatives, followed by nucleophilic substitution reactions with sodium azide, potassium fluoride, ammonia, methylamine, and 4-nitroimidazol, respectively, gave substituted 4-amino-3,5-dinitropyridine derivatives. Meanwhile, its azide derivative underwent a ring closure conversion into 7-amino-6-nitro-[1,2,5]oxadiazolo[3,4-b]- pyridine-1-oxide. It is of significance that all of the nucleophilic substitution reactions were carried out under mild conditions. 展开更多
