use of catalysts while minimizing potential chemical accidents. Results and Discussion The Oxone epoxidation reaction is a two-step mechanism that includes forming the dioxirane first. The second step is using the dioxirane to attack the trans-anisole. The mCPBA reaction is a one step that forms the trans-anethole oxide. The result of the Oxone epoxidation reaction yielded 0.96 g of product which was 65% yield. The result of the mCPBA epoxidation reaction yielded 1.03 g or product which was 70%

This name‚ meaning rock oil‚ is applied to certain bituminous fluids found in the earth. Solid bitumen‚ or asphalt‚ differs but little in chemical composition from petroleum‚ both being compounds of carbon and hydrogen Many varieties of petroleum‚ and perhaps all‚ become thicker by exposure to the air‚ and finally solid‚ resembling asphaltum. Bitumen‚ and doubtless petroleum also‚ was known from the earliest ages‚ being the "pitch" which Noah used in building the Ark‚ and the "slime" used for

EXPERIMENT 8 BOILING POINT n-Butyl Alcohol n-Butyl Alcohol‚ a four carbon straight chain alcohol‚ is a volatile‚ clear liquid with a strong alcoholic odor; miscible with water. It is flammable strongly with a luminous flame. Formula: C4H9OH Boiling point: 118 ºC Melting point: -89 ºC Tert-Butyl Alcohol Tert-Butyl Alcohol or “2-methyl-2-propanol” is the simplest tertiary alcohol. It is one of the four isomers of butanol. Tert-Butanol is a clear liquid (or a colorless solid‚ depending on

2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent (Sodium bicarbonate or Sodium hydroxide)) by the solubility in
