the reaction of cyclopentadiene with itself as it will dimerize to form dicyclopentadiene if kept at room temperature as well as the exo isomer of the product. Reaction Mechanism: Experimental Procedure To begin this experiment‚ a fractional distillation was set up in order to distill dicyclopentadiene. A 10 mL conical vial was filled with 5 mL of dicyclopentadiene and then heated to a steady boiling point (40-42 C). Cyclopentadiene was then placed on ice while

Homogenous mixtures has components that are indistingushable with each other e.g. (colloids) while Heterogenous mixtues ’ components can be distinguished from each other e.g. (suspensions). Mixtures can be separated by physical changes through distillation‚ decantation‚ evaporation‚and the use of magnet. Materials and Methods The reagents that we used are the following: Iron fillings‚ Distilled Water‚ Sodium Chloride (NaCl)‚ Sulfur. The equipments:100ml Beaker‚ Bunsen Burner‚ watch Glass‚ Stirring

solute - Boiling is a much quicker process than evaporation and therefore is more commonly used - The technique is based on the large differences in boiling points of the solute and solvent - THIS TECHNIQUE DOES NOT RECOVER THE LIQUID Distillation or simple distillation - This is a technique of separating two or more liquids or separating the liquid from the solids in a solution but also retrieving the liquid component - This technique relies on a difference of at least 50ºC in boiling point between

refinery construction costs based upon the distillation & upgrading capacity a refinery has. The index assigns a complexity factor to each major piece of refinery equipment based on its complexity and compared with simple crude distillation‚ which is assigned a complexity factor of 1.0. The complexity of each piece of refinery equipment is then calculated by multiplying its complexity factor (Table Below) by its throughput ratio as a percentage of crude distillation capacity. Adding up the complexity values

Experiment 13B: Isopentyl Acetate (Banana Oil) Semimicroscale Procedure Taylor Levin 5.28.14 Chemistry 352- Organic Chemistry Lab Summer 2014 Purpose: To prepare isopentyl acetate (banana oil)‚ an ester‚ from isopentyl alcohol and acetic acid through the Fischer Esterification reaction. Reactions: acetic acid + isopentyl alcohol isopentyl acetate + water C2H4O2 + C5H120 CH3COOCH2CH2CH(CH3)2 + H20 Procedure: A reflux condenser was assembled

products begin to form‚ hydrolysis a reverse reaction of esterification occurs. To ensure the reaction is complete an acid catalyst is commonly used. The catalyst is usually concentrated sulphuric acid. This experiment covered 4 techniques; they are distillation‚ refluxing‚ extraction‚ and esterification. Firstly‚ esterification and refluxing‚ the acid and alcohol are first warmed and mixed together with the sulphuric acid catalyst then attached it to a reflux condenser for a period of time. Then extraction

205 I. Title and Equation: Unimolecular Elimination + 2 Isomers II. Experimental Procedure : In a flask‚ 0.081 mol of 2-methycyclohexanol and 3 mL of 85% H3PO4 were mixed. The mixture was boiled under a fractional distillation column‚ and 7 mL of the distillate was collected. The organic and aqueous layers were separated and the organic layer was dried with anhydrous sodium sulfate. The product was analyzed using GC. III. Conclusion: In this experiment‚ 2-methylcyclohexanol

or sodium sulfate. Because isopentyl alcohol has a lower boiling point than that of isopentyl acetate‚ and the by-products have higher boiling points‚ it should be possible- in principle- to remove the alcohol and by-products from the ester by distillation. Isopentyl alcohol should distill first‚ followed by the ester‚ and any by-products should remain behind in the pot-the vessel in which the reaction mixture is boiled. Reaction: Reaction: Acetic acid + isopentyl alcohol isopentyl acetate
