The results obtained were as follows: afterglow time 253.67 sec, flame duration 113.33 sec, flame propagation rate 20.3x10-2cm.s-1, ignition time 2.33 sec, thermal conductivity 51.34x102Umoh/cm, electrical conductivity 5.3x10-3Sm-1, ash content 3.4%, moisture content 29.97%, oven dry density 22.3x10-2g.cm-3, water imbibitions (at different time intervals: 30 mins 46.6%, 5hrs 87.6% and 24 hrs 148.9%), etc, These results showed it to be a good timber suitable for various construction purposes. The elemental analysis obtained through Atomic Absorption \u0000Spectrophotometer (AAS) indicated the absence of Ca, as well as the presence of Na, K, Pb, Mg, Zn, As, Cu, Hg and Cd in their decreasing order of magnitude respectively as follows: 1.07%, 0.08%, 0.08%, 0.07%, 0.05%, 0,02%, 0.01%, 0.01% and 0.003%. Thin Layer Chromatographic (TLC) analysis gave Retardation factor (Rf) value of 0.62 in the chloroform-methanol extract. The phytochemical screening showed the presence of all the tested secondary metabolites except steroids which indicated its therapeutic ability. Their proportions are indicated thus; saponins (10.2%), tannins (920 Mg/100 g), flavonoids (8.0%), carbohydrates (1.62 Mg/g), proteins (1.55%), glycosides (356 Mg/100 g) and alkaloids (5.6%). The Fourier Transform Infrared (FTIR) and Ultraviolet (UV) spectra suggested that the active compound might be 1,2,3-trisubstituted aromatic compound with C=O, O-H and C=N groups attached. The chemical components analysis showed the presence of cellulose 43%, hemicelluloses 20%, lignin 29% and other constituents in their right \u0000proportion.

The chemical structures and molecular weights were characterized by means of nuclear magnetic resonance ( 1 H-NMR). The values of t 1/2 and the equilibrium melting temperature for all samples were calculated by Avrami equation and HoffmanWeeks, respectively. The crystal structure of the copolyamides were also investigated by wide-angle X-ray diffraction (WARD). The results shows that: (1) Avrami model can be used to well describe the isothermal crystallization behavior of the copolyamides, and all the values of t 1/2 increase with increasing the Tc or the mole fraction of nylon 510. (2) The crystallization activation energy ( ∆E) and nucleation constant ( Kg) both increase with increasing the mole fraction of nylon-510, which indicating that the addition of nylon nylon-510 decreases the crystallization rate of copolymer.","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"6 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82275257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plots of dielectric constant ε and loss factor ε against the frequency were found useful in determining how well experimental data fits the Debye equation and these methods were also found capable of reproducing good results of fitted data using doubleDebye. The dielectric constant of Propan-1-ol was found to decrease as the temperature increases beyond 10oC whereas that of Propan-2-ol increased at the temperature 20oC. It then decreased as the temperature increased beyond 20oC. The loss factor on the other hand was found decreasing as the temperature increases for both Propan-1-ol and Propan-2-ol.

Experiments were performed under atmospheric pressure. The obtained products and compositions based thereon can be used as inhibitors of mineral scales. Products were prepared at four different composition of components and named DASS-1 to DASS-4. Optimal conditions for the production of desired products are defined. All synthesized products have inhibitory properties, but their individual application for waters with high hardness do not provide the desired result and approximately 50-80 % lower than the standard reference industrial scale inhibitors. However, high effective inhibitors were developed through preparing a composition in equimolecular proportions of the synthesized products with IOMS-1 and OEDP. The inhibition efficiency of the product of DASS-1+OEDP with a concentration of 3.0+2.0 reaches 96.5% at a water hardness of 4-5 mEq/L (about 30% efficiency) and 92.0% at 13-14 mEq/L (10% efficiency). It is proved that the inhibitory properties of complexons (chelating agents) were clearly affected by the denticity of complexing ligands.","PeriodicalId":7399,"journal":{"name":"American Chemical Science Journal","volume":"120 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82586852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
