The results of the study showed that the deposits consisted of phyllosilicate minerals such as kaolinite, illite and clinochlore; other mineral present were quartz, sanidine high, geonalite, diaspore and and lepidocrocite. The clay minerals exhibited moderate swelling characteristics and medium plasticity; the linear shrinkage and apparent porosity were within the accepted values for refractory clays. It is reddish-brown colour on account of the presence of coloured iron mineral lepidocrocite. The clay minerals also exhibited good thermal shock resistance and refractoriness above 1200oC. The properties of the clay mineral deposits were reflection of the combined effects of the properties of the clay minerals and other non-clay mineral constituents. The study revealed that the clay mineral deposits studied had good refractory characteristics and can be used at operating temperature conditions above 1200oC. \u0000 ","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73052071","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}

In this study, the essential oil of P. togoensis was obtained using hydrodistillation method while the alcoholic extract was obtained using aqueous methanol. The alcoholic extract was thereafter silylated using N, O-bis-(trimethylsilyl) trifluoroacetamide containing 1% trimethylchlorosilane. Both the essential oil (PTEO) and silylated extract (PTSE) were analysed on GC-MS and investigated for antioxidant and enzyme inhibitory activities using DPPH, alpha-glucosidase and porcine pancreatic lipase enzyme. Principal classes of compound identified in PTEO were monoterpenoids (12.30%), sesquiterpenoids (24.14%) and diterpenoids (21.26%) while the PTSE indicated preponderance of sugar and fatty acids, with fructofuranose (20.31%), mannose (24.14%) and palmitic acid (6.32%) as major constituents. The IC50 of DPPH radical scavenging potentials of PTEO (435.81±1.25 µg/mL) and PTSE (280.09±1.14 µg/mL) indicated that both extracts exhibited mild activities which were lower than the standard ascorbic acid (32.61 ± 2.60 µg/mL). Also, hypoglycemic activities of PTEO (308.26±3.67 µg/mL) and PTSE (363.45±2.55 µg/mL) were fairly comparable to the acarbose (279 ± 4.21 µg/mL).

Na-CMC at different concentrations (200ppm - 2000ppm) was mixed with constant volume of disodium hydrogen phosphate solution in a graduating measuring cylinder. On mixing the resulting solution with constant volume of nickel chloride solution, a precipitate was formed, stirred for 1 min and placed in the sedimentation measurement device - PreSed Meter. The settling of the precipitate was monitored and recorded at different temperatures (30oC, 40oC and 50oC). Blank sedimentation (0ppm Na-CMC) was also run at various temperatures by adding 10ml of deionized water (instead of 10ml of Na-CMC solution). A plot of precipitate displacement per settling time established a logarithmic curve which flattened with time. Regression analyses of OSR (0.71 ≤ R2 ≥ 0.94) and SVR (0.51 ≤ R2 ≥ 0.93) indicated the dependence of sedimentation on concentration of Na-CMC thus implying chemical interaction between the chemical species. \u0000 ","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83054624","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}

In this study, a Simple Thin Layer Chromatographic method is described for the qualitative detection of Sudan-I, II, III & IV in palm oil gotten from different markets. The study includes extraction of sample, preparation of Thin Layer Chromatography (TLC) plates, Separation, detection and visualization of dyes on TLC plates. The dyes were extracted with solvent Acetonitrile. Sample extracts were decanted and analysed by simple thin layer chromatography in hexane, chloroform and acetic acid solvent system. The chromatograms of samples and standards were stained with Iron (ii) chloride stain and further evaluated in term of Rf values. Out of the five samples analysed the Rf values of the colouring spots from the three samples L2, L3 and L4, matched the standards (S2). It is therefore, concluded that samples L2, L3 and L4 contain Sudan IV dye. Without using any derivation, the limit of detection (18mg/L for S2 (Sudan IV dye) and 10mg/L for SI (Sudan III dye) was determined by visually determining if a spot was visible or not at a certain concentration of standard dye. \u0000 ","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88798966","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 gravimetric technique was done for 5 Hours. Results indicate that the leaf extract inhibited the corrosion process efficiently. The extract showed inhibition efficiency of 84.95% and 84.24% (333 K) for gravimetric and gasometric analysis respectively. The Inhibition efficiency was found to increase with an increase in the extract concentration and also increased with an increase in time but decreased with increase in temperature. Thermodynamic considerations revealed that the activation energy, Ea increased in the presence of the plant extract. The kinetic data confirmed the reaction process to be first order.
