Synthesis of Dulcin - Sugar Essay Example

Drying agents (also called desiccants) come in various forms and have found widespread use in the foods, pharmaceuticals, packing, electronics and many manufacturing industries. A desiccant is a hygroscopic substance that induces or sustains a state of dryness in its vicinity. Ideally, it is chemically stable and chemically inert (i.e., silica). Unfortunately, this is not always the case in the chemistry lab because the drying agent comes into direct contact with the solvent and the chemical.

In the synthesis of Dulcin, which of ..

O chem lab for synthesis of acetaminophen

reflux!
Week 3:
Analyze dulcin through MP, IR, H NMR, and mass
Summary of Results
Experimental & Literature Spectra for Products Phenacetin and Dulcin
Phenacetin
Dulcin (?)
Possible Errors
Week 1
Not drying the product enough by using an oven/heat source
Thought drying in drawer would be sufficient
Week 2
pH adjustment
Use liquid sodium bicarbonate
Burning the reaction mixture
Phenacetin was positively identified the first time, but the reaction was not able to continue to dulcin due to this
Week 3
Impurities in the phenacetin H NMR tube
Conclusions
Sources
