 * __Microscale Dehydration of Cylcohexanol (Using Glassware with Elastomeric Connectors) – Regular Quantities__**

For microscale dehydration of cyclohexanol, the following materials and chemical reagents were used to set-up and conduct our experiment:

Distillation apparatus (from lab provided distillation kit – //refer to the figure link to view set-up//) - elastomeric connectors - glass components - 5 mL //flat// bottom flask (2 – one for solution to be distilled, and one acting as a receiver vial). Support stands (2) Utility Clamps (3) Sand bath (1) Hot Plate (1) 50 mL beaker (for ice bath) 5 mL sample vial (1) 10 * 75 mm test tubes (multiple) Magnetic stir bar (1) Multiple pasteur pipets (with Latex bulbs) Thermometers (2)
 * Materials:**

Calcium Chloride (anhydrous = dry) 0.25 g; irritant and hygroscopic Cyclohexanol 1.422 g; irritant and hygroscopic Cyclohexene; flammable and irritating Phosphoric Acid, 85% 1.5 mL; corrosive Sulfuric Acid, Conc. 0.12 mL; toxic and an oxidizer
 * Chemical Reagents** **& Quantities; Caution**
