Experiment 1: Simple Distillation and Boiling Points- Separation of Liquids February 24‚ 2014 Analysis In this experiment‚ the distillation of three groups of two miscible liquids was performed. First‚ Ethanol and 2-Propanol were distilled. The boiling points of ethanol and 2-propanol had a difference of 5°C. The percent recovery for both ethanol and 2-propanol were both 0%. The percent recovery of the intermediate was 96%. The percent efficiency calculated of ethanol and 2-propanol was 0% efficient

Lab 22: 4-Methylcyclohexene Abstract: We treated 4-methylcyclohexanol with phosphoric acid‚ and after purification we produced the end product 4-methylcyclohexene. We determined we had a pure product based on the results of the tests with Br2 and KMnO4‚ as well as the IR absorbtion spectrum of the final product. Purpose: The purpose of this experiment is to obtain pure 4-methylcyclohexene by reacting 4-methylcyclohexanol and phosphoric acid. Through distillation

Procedure: The addition of 4.0 mL cyclohexanol‚ 1.0 mL of 85% phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate

Synthesis and Structure of Alcohols Alcohols can be considered organic analogues of water. H O H R O H Alcohols are usually classified as primary‚ secondary and tertiary. H R H OH H primary R R OH R R OH OH R secondary tertiary phenol Alcohols with the hydroxyl bound directly to an aromatic (benzene) ring are called phenols. Nomenclature of Alcohols (Normally any compound’s name which ends in –ol is an alcohol of some sort) IUPAC rules that:

Formation of an Alkene by Alcohol Dehydration Lab Report Balanced Chemical Equation for the Main Reaction Mechanism The acid-catalyzed dehydration of secondary and tertiary alcohols involves non-isolable carbocation intermediaries. In the first step of the of the reaction mechanism below‚ a phosphoric acid catalyst adds a proton to the oxygen atom of the alcohol to form an oxonium ion. The OH is converted to a better leaving group as the positive charge on the oxygen weakens the carbon-oxygen

In order to study the influence of reaction time‚ acetophenone with complex 2 (0.1 mol%) under standard conditions was monitored by GC-MS analysis taking 0.1 mL aliquots of the reaction mixture at intervals of 1 h. As can be observed in the conversion vs time plots‚ the formation of 1-phenylethanol was increased with the progress of the reaction‚ reached a maximum and then remained unchanged (Fig. 4). Reasonably good conversion (97.4%) for the formation of 1-phenylethanol was observed at the optimum

Upon addition of bromine‚ the brown color of bromine quickly disappears as the bromine adds to the double bond in the products. Addition of bromine to the fractional distillate caused the bromine to discolor. The addition of bromine to 2-methyl-cyclohexanol remains brown because there is an absence of double bound (saturation). Addition of potassium permanganate caused the solution to turn slightly brown but appeared immiscible as result of the unsaturation product. When analyzing the IR results confirmed
