December 5, 2007 Craig Nutter Section #9, Wednesday 2:30 Experiment 10 Title: Dehydration of Alcohols to Generate Alkenes Objective: To determine the mechanism of dehydration of alcohols and to compare the relative reactivities of primary, secondary, and tertiary alcohols. Reaction: Reagent Table: Starting Material Amount Added 1-butanol, 2-butanol, or 2-methyl-2-propanol 200μL (2:1) Concentrated H 2 SO 4 and H 3 PO 4 50μL Procedure and Observations: Questions from handout: 1. The initial gas emitted may contain impurities from the inside of the tube. 2. This will cause a vacuum effect and draw water back in. 1. Unsaturation of 0. 2. CH 3 CH 2 CH-OH-CH 3 , CH3CH-OH-CH 2 CH 3 , and CH-OH-CH 2 CH 2 CH 3 3. CH3CH2CH2CH=CH2 and CH3CH=CHCH3; 2 Isomers yielded the same product.

Procedure: 1. A set up of collection devices was formed using a red pieblock with a thermometer, cap, and a o-ring was put on 3 glass delivery tubes. 2. 200 uL of alcohol was transferred into a 3 mL conical vial. 3. 50 uL of concentrated acid mixture was added three glass vials with different alcohols in each, the addition on the acid was simultaneous. 4. Attached glass delivery tube to each vial tightly. 5. The vial was positioned into the red pieblock on the hot plate. 6.
