Experimental Procedure
Comparative Example 1
Isobornyl Methacrylate without Lithium Bromide
A 3-L 4-necked round-bottomed flask equipped with a mechanical stirrer, air sparge (10-15 mL/min), thermocouple, 12-inch column (packed with 0.20 inch Propak packing, approximately 6 plates), and variable reflux head is charged with 588 g (3 moles) of isobornyl acetate, cyclohexane (300 g), and methyl methacrylate (450 g, 4.5 moles).
The reaction mixture is brought to reflux and about 10 mL of cyclohexane/H2 O is distilled out over approximately 15 minutes.
A solution of 10percent lithium t-butoxide in cyclohexane (40 g, 0.05 moles) is added and the reaction placed under total reflux until the head temperature drops to 57° C.
The cyclohexane/methyl acetate azeotrope is removed at a reflux ratio of 9:1.
The head temperature remains at 57° C. for the first two-thirds of the reaction and then slowly rises to 70° C. at the conclusion while the pot temperature rises to about 105-110° C.
The reaction is continued until the ratio of isobornyl methacrylate to isobornyl acetate exceeds 100.
Once the reaction is complete, the batch is cooled to 80° C. and acetic acid (5.4 g, 0.09 moles) is added.
The remaining cyclohexane and methyl methacrylate are removed via vacuum distillation (70-80° C.).
When the crude product is dissolved in (2/98 vol/vol) in methanol, a cloudy white precipitate forms.
The crude product is diluted with an equal weight of cyclohexane and washed with 20percent by weight of 20percent caustic.
The two phases do not separate on prolonged standing.
This result as well as the large quantity of precipitate produced on dissolving the crude reaction mixture in methanol indicate the presence of polymer in the reaction mixture.
