Various paths and models have been tested for more accurate VLE predictions for 36 binary systems with 376 data points and 14 ternary mixtures with 368 data points,especially for mixtures of industrial interest in refrigeration units.
Reduced crude is considered usually as the main source for heating oils.Therefore, it was chosen in addition to, a commercial fuel oil in the present investigation, to improve their ability for pipelining.
Batch distillation process is one of the major operations in the chemical, petroleum and pharmaceutical industries for the separation of liquid mixtures into their pure components The present work is concerned with constructing a simulation computer programs to analyze multi-components,multistage batch distillation without and with chemical reaction.The rigorous method was used to build the simulation computer programs for non ideal mixtures, by using MATLAB package to solve MESH and MESHR equations.
This work consists of synthesis of new oxazepine and diazepine compounds according to the Schemes shown below.
In order to obtain the target compounds, the following routes were adopted:-
In this research the effectiveness of sawdust SD and Sawdust coated polyaniline SD/PANI composite, which is one of the environmentally friendly materials, cheap and available in very large quantities were testing to remove the bromothymol blue BTB and malachite green oxalate MGox dyes as chemical contaminants for industrial bio-waste water using Batch Adsorption technique.
In this work the synthesis of Au-doped and Pt-doped TiO2 nanoparticles employing sol-gel methodology. The doping procedures based on chemical reduction and UV photodeposition.
The present work includes the synthesis of different Schiff’s bases [3(A-C)] by the reaction of 2-Aminopyridine [2] with benzaldehyde and its derivatives [1(A-C)]. These Schiff’s bases react with benzoyl chloride [4] to yield benzamide derivatives [5(A-C)]. The synthesis of L-amino acid derivatives [6(A-C)–10(A-C)] has been performed by the reaction of benzamide derivatives [5(A-C)] with (Glycine, L-Alanine, L-Phenylalanine, L-Asparatic acid and L-Asparagine).
This study involves the preparations of some pyridine derivatives starting from Isonicotinic acid (1) following these steps :First : The Synthesis of Isonicotinoyl acid chloride (2) by The reaction of Isonicotinic acid (1) and thionylchloride .Second : The Synthesis of some amide and ester derivatives by reaction between Isonicotinoyl acid chloride (2) and substituent amine or phenol derivatives ( Semicarbazide, Thiosemicarbazide, Benzohydrazide, Aniline, 4-phenylazoaniline, 4-phenylazophenol, p-Aminophenol, p-Aminoacetophenone, m-Toluidine, 4-Bromoaniline )
Room temperature ionic liquids gained massive growth in recent years for their distinguished characterization like non-volatile and designed media for variable chemical and industrial application. In addition, indium metal has applications in electronic and optoelectronic devices, tin and antimony metals have good corrosion resistance and optical properties respectively.
This study is concerned with the synthesis and characterization of some new liquid crystalline compounds derived from di- and tri-hydroxy benzoic acids with bis-swallow tailed which called N,N`-1,4-phenyl-bis[3`,5`-disubstituted benzamide] , N,N`-4,4`-biphenyl-bis[3``,5``-disubstitutedbenzamide], N,N`-1,4-phenyl-bis[3`,4`,5`-trisubstitutedbenzamide] and N,N`-4,4`-biphenyl-bis[3``,4``,5``-tri substituted benzamide] which were synthesized according to the following schemes(1, 2, 3, 4):
