Synthesis of N-(4-Chlorophenyl)maleimide lab report

You should have:

Purpose
Name, Structure, Physical properties, and Hazards of ALL chemicals

Physical properties: MW, mp/bp, density, color, solubility in water
Hazards: NFPA codes, LD50, precautions beyond goggles and lab coat (if applicable)

Procedure (left side of page, past tense)
Drawings of an unusual, complicated, or new apparatus
Observations (right side) of

starting materials, crude products, purified products
colors, state changes, etc… during reaction
masses (starting materials, crude products, purified products etc…)
characterization observations (mp/bp)
Also any alterations to the procedure

Drawings of TLC plates (to scale, indicate spot colors, indicate visualization method)
Results and calculation section

Summary of characterization data:

Experimental mp/bp values

Also list literature values of starting materials, desired products, and any likely side products for comparison

Major peak values and characteristic (broad/sharp strong/weak) from IR with functional group assignments
Peak shifts, splitting and integration values from 1H NMR

Assign these peaks to the expected product molecule or to common NMR impurities from the bookmark in CC (MUST CITE impurity assignments)

Impurities may be water, acetone, CHCl3 if using CDCl3, dimethylsulfoxide (DMSO) if using D6DMSO

Calculations

Percent yield (actual yield / theoretical yield * 100%)
Atom Economy (MW desired product / S MW starting materials * 100%)
Effective Mass Yield (EMY) (mass product / mass hazardous reagents * 100%)

Must indicate how you define “hazardous”

E-Factor (mass total waste / mass product)

Conclusions

For EACH STEP make a conclusion if the reaction was successful

What evidence supports that you created the desired product?

Be specific, use ALL of your characterization data
State if there is any conflicting characterization data

Was your reaction efficient?

Use % yield, and Atom Economy

Was your product pure?

If the characterization data suggests there is impurities, is it easy to remove solvent, or is there evidence of some side product that may be harder to remove?
