According to the studies, increasing the injection pressure at the surface will not have much effect on increasing the production flow of the well therefore, taking into account the economic cost, making changes to increase the injection gas pressure is not justified. Increasing the injection gas flow rate will cause a significant increase in the production flow. Therefore, it is recommended that control valves cannot be installed in order to control the injection flow gas due to the operational limitations, by installing appropriate reducers in the injection flow gas path to increase the oil flow. In order to investigate the effect of increasing injection gas flow rate on production from one well, one injection of gas with flow was performed at about 12000000 SCF / DAY and again injection rate was increased to 15000000 SCF / DAY and then the results were compared.

This study relates to an improved method for they preparation of hydrazodicarbonamide, an intermediate in the preparation of azodicarbonamide which is useful as a chemical blowing agent. Hydrazodicarbonamide is prepared by reaction of urea and hydrazine in acidic medium. Hydrazine is a relatively expensive chemical and this is reflected in the cost of materials derived from it. Accordingly any means of effecting a substantial increase in the yield of hydazodicarbonamide from hydrazine is commercially very important. By Series of comparative experiments, Factors of influencing the yield of biurea which is prepared from the condensation reaction between hydrazine hydrate and urea are studied.

In the present work, an activated carbon material has been prepared from date pits to remove zinc (Zn2+) and copper (Cu2+) from a wastewater. The effect of some parameters on adsorption performance has been investigated. The optimization of operational conditions allowed increasing the adsorption of Zn2+ ions from 33% to 85% and the adsorption of Cu2+ from 23% to 70%. The optimum conditions found are a mass of adsorbent of 4g, a stirring speed of 500 rpm and a ratio of 15 for volume of liquid / mass of solid. It has been shown that the adsorbent has more affinity to the copper ions than zinc ions and the modeling results gave adsorption isotherms type “C”. The results also showed that the kinetics of zinc and copper ions adsorption were described by a pseudo second-order rate model and controlled by the internal diffusion which can be considered as limiting step that controls the rate transfer of these ions to the solid surface.

Functional dye is a new term in the field of dye chemistry which has been specifically designed for high-technology applications such as solar cells, photochromic dyes, liquid crystal, electrophotography, fluorescent sensors and photodynamic therapy. BODIPY and its derivatives as organic fluorophores have optical properties and can be used as potential sensors in various applications for biotechnological, industrial and medical purposes. In this research, a group of a new fluorescent indicators based on BODIPY structure were designed which have been composed from two seven-membered rings including Al or B atoms that has been connected with methine bridge complexed with NH2 or PH2 center. The geometries, optical properties and electronic structures of various designed molecules were studied using time-dependent density functional theory (TDDFT). The results of the calculations showed that the new designed structures are stable and highly optically active with considerable quantum yield (Φ) absorption and emission as if is promising candidates for hi-tech different applications.

Herein, a highly efficient, simple, base-free, chemoselective and environmentally-benign strategy was developed for the reduction of nitro compounds using NaBH4 as a hydrogen and electron source in the presence of a bimetallic and low-cost nanocatalyst (Fe3O4@Ni-Co-BTC NPs). Thanks to inimitable structure of Fe3O4@Ni-Co-BTC NPs, this nanostructured catalyst exhibits superior catalytic performance for the reduction of a wide library of electron-donating and electron-withdrawing aromatic, heteroaromatic, heterocyclic and aliphatic nitro compounds. Interestingly, the aforesaid nanocatalyst showed high reactivity and chemoselectivity for the reduction of the nitro group in the presence of other reducible functional groups such as COOH, CHO, COCH3, CN, NHAc and OCOCH3. Furthermore, due to the superparamagnetic nature of Fe3O4@Ni-Co-BTC NPs, it could be easily separated from the reaction mixture and reused for at least seven consecutive recycle runs while its activity and selectivity was preserved. Performing the reaction at room temperature and in a green media is another notable feature of the present method.

p-Xylylene bis(triphenylphosphonium tribromide) (XBTPPTB ) could be used for selective oxidation of sulfides and thiols to their corresponding sulfoxides and disulfides as an effective and green reagent, under nonaqueous and aprotic conditions without catalyst. This reagent can be recovered and reused several times. Also it is readily prepared and could be stored for months without losing its potency. To study the effect of solvent, oxidation of benzenethiol was performed in different solvents. Acetonitrile is the best solvent due to the relatively good solubility of the catalyst and starting materials. To study the effect of solvent, oxidation of methyl phenyl sulfide was performed in different solvents. Actonitrile is the best solvent due to the relatively good solubility of the catalyst and starting materials. The effect of catalyst amount was investigated and the optimum ratio of reactant to oxidant (1:0.5) is found to be ideal for complete conversion of sulfides and thiols to the corresponded products.
