According to the data of chromatography-mass spectroscopy, the relative distribution of n-alkanes of oil was determined to calculate the naphthenic oil passport from various horizons and depths. It is shown that oil is of paraffin-naphthenic type, hydrocarbon composition of oil samples varies depending on the horizon and the depth of occurrence. Oil is characterized as light, average catagenetic transformation and refers to the glandular type. Mother rock of sedimentary type are of the clay type. The studied geochemical characteristics of oil indicate a biogenic genesis and differentiation of oils by characteristic biomarker indicators, and also make it possible to predict the composition and type of oils in deposits with a simular geological structure.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":"18 1","pages":"30-36"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90443340","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}

Molecular weights (medium, high and very high) polyacrylamides were synthesized using potassium persulfate and N,N,N',N'tetramethylethylenediaminesystem as initiators. The synthesis of medium, high and very high molecular weight polyacrylamides were achieved by increasing the concentration of acrylamide monomer. Fourier Transform Infrared Spectroscopy (FTIR) of polyacrylamides showed strong absorption at wave number 1655 cm -1 due to the presence of primary amide band. The results also showed that the increase in the intrinsic viscosity and glass transition temperature were proportional to the increase in molecular weight of polyacrylamide.

There are different methods are used to synthesis the natural dyes on each flower. Then they are analysed by GC-MS, UV-Visible and IR Spectroscopy instrumental analysis. The instrument anlaysis reveals the structural conformation of natural dye collected from each dye. The mordant are important chemical component which is used to add with natural dye to enhance the colour strength of natural dye collected from the above flowers. In this project we use the alum, potassium dichromate, copper chloride and stannous chloride are used as mordant to increase the colour strength of each natural dye collected from the concerned flowesr. The colour strength is analysed with DATAColor Spectrophotomete. Wast fastness, Xenon fastness test are also carried out. From above test we conclude the strength of colour is increased by means of the stannous chloride mordent used compared to other mordants applied to the cotton dyed with the natural dyes extracted from the hibiscus rosa sinensis and marigold flower.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":"1 1","pages":"74-79"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83039216","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}
