Esterification, Design of a Procedure Report

CHemistry 266 Spring 2007

20 Points  

A. Turn in your ester samples in a labeled bottle.  Include (4 pt., deductions will apply for lower yield, off boiling points and poor quality of product)

· Compound Name

· Your name

· Date

· Weight of Product (original at the end of distillation)

· Tare Weight of Bottle

· NFPA #'s

· boiling Pt.

Please fill out the report in the following order

B. Your Name (-0.5 pt. if missing)

C. Date (-0.5 pt. if missing)

D. Experiment Title and Number (-0.5 pt. if missing)

E. Write the equation of reaction (1 pt)

F. Write the procedure in a journal style format. Include the IR, ¹H and ¹³C NMR data in the procedure. Use this link and see the experimental section as an example of how to write the procedure and how to incorporate the data including mp, IR, NMR and MS in the procedure. The procedure will be worth 4 pt. The following deductions will be applied

· No yield stated in procedure -0.5 pt.

· No % yield given procedure -0.5 pt.

· Incorrect yield calculation -0.5 pt.

· Boiling pt. not given in procedure -0.5 pt.

· IR data missing in procedure -0.5 pt.

· NMR data missing in procedure -0.5 pt.

· Any unclear or incorrect statements (-0.3 pt. each)

· Spelling errors particularly for compounds, techniques, apparatuses, and instruments (-0.2 pt. each)

· Overall report is not typewritten (-2 pt.).

H. Staple IR, ¹H, and¹³C NMR spectra to the report (3 pt. with possible deductions for poor quality).

G. Interpret principal peaks in the IR spectrum of the product. (2 pt.)

H. Assign peaks in the ¹H NMR spectrum to the corresponding protons of the ester. (3 pt.)

H. Assign peaks in the ¹³C NMR spectrum to the corresponding carbons of the ester.(3 pt.)
