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%

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

Panacetin‚ a type of pain-killer. Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base properties. Then‚ the percent composition of Panacetin can be deduced based on the masses
