Experiment Part A) Solubility of Alkanes: 1 mL of nine solvents (water‚ methanol‚ n-butanol‚ ethylene‚ glycol‚ acetone‚ hexane‚ toluene‚ ethyl acetate‚ and dichloromethane.) was added to nine sample vials. Each vial then had 0.5 mL of the alkane decalin added to each one. The mixtures were stirred to determine if the materials dissolved. If the material was insoluble it was heated

Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

In effect‚ refineries use fluid catalytic cracking to correct the imbalance between the market demand for gasoline and the excess of heavy‚ high boiling range products resulting from the distillation of crude oil. As of 2006‚ FCC units were in operation at 400 petroleum refineries worldwide and about one-third of the crude oil refined in those refineries is processed in an FCC to produce high-octane gasoline and fuel [4][5] oils.
