expected triphenylmethanol. The identity of the product being correct was further confirmed by way of both proton and carbon-13 NMR spectra. This is due to the fact that both spectra yielded peaks that contained the main structural residues‚ alcohol and aromatic groups‚ of triphenylmethanol. The final yield of pure triphenylmethanol was 8.04 grams‚ resulting in a percentage recovery of 67.7%.

the structure had to add up to 148. ATR-IR suggested the presence of an aromatic ring‚ alkene group and carbonyl group. CNMR showed the presence of an aromatic ring‚ carbonyl group and a methyl group. HNMR showed the presence of an aromatic ring‚ alkene group and carbonyl. Using the rule of 13 and the adjustment for oxygen‚ the predicted structure of the anise oil was C10H12O with 5 degrees of unsaturation. Since the aromatic ring is 4 degrees of unsaturation by itself‚ the last degree of unsaturation

Unit-1 Petroleum Exploration — An Introduction Objective: After reading this unit you would be able to understand: What are hydrocarbons? What are their properties? What are the main products derived from crude oil and their uses Exploration milestone-an overview. INTRODUCTION: By definition petroleum is a generic name for hydrocarbons‚ including crude oil‚ natural gas liquids‚ natural gas and their products. Petroleum comes from the Latin petra meaning rock or stone & oleum meaning oil. Petroleum

therefore‚ depicting an carbonyl functional group. Table 2 also demonstrates a peak was present at 1583 cm^(-1)‚ this peak represents an aromatic ring being present in the molecule due to an aromatic ring’s literature value ranging from 1600-1475 cm^(-1). N‚N-diethyl-toluamide’s literature IR spectrum has a peak at approximately 1475 cm^(-1)‚ therefore‚ representing an aromatic ring (Webbook.nist). Table 2 also exemplifies a peak was present at 2943 and 2970 cm^(-1). Alkanes have a literature range ranging

responsible for the largest amounts of natural gas (Foote et al.‚ 1988). In a petroleum system like the Smackover Formation‚ it is important for traps to be present so that the hydrocarbons are unable to escape. However‚ Locklin‚ 1984‚ page 41‚ makes a clear argument why "apparent Upper Jurassic reservoir rocks have not trapped hydrocarbons more frequently." He reasons that potentially “large faults have caused breaking of mineralized seals and created excessive fracturing along a fault plane‚ which allowed
