YieldReaction ConditionsOperation in experiment
83 %Chromat. at 45℃; for 2 h; Autoclave; Inert atmosphere; Large scale Into a suitably sized and jacketed reactor were placed a mixture of exo-/endo- norbornene methylacetate (>99.6percent purity, 4.8 kg) and methanol (11.2 kg). The reactor was equipped with an agitator, overhead condenser, overhead condensate receiver tank, and feed tank with metering pump. The temperature of the reactor was controlled by a dedicated oil circulation unit; reactor pressure was manually controlled, with nitrogen addition to increase pressure and vent takeoff to decrease pressure.The reactor was purged with nitrogen using three pressure/vacuum swings to remove any oxygen in the reactor headspace. After this nitrogen purge process, the reactor was left in a fully vented mode through the overhead condenser and receiver system, and then heated to the initial reaction temperature (45°C). A catalyst solution consisting of sodium methoxide in methanol (25wtpercent, 0.125 kg) was added to the glass feed tank and then metered into the reactor over a 15 minute period (addition rate 8.33 g min), while maintaining reactor temperature (45°C). After completion of the catalyst metered addition, the reactor was maintained at temperature (45°C) for an additional 1.75 hours. After completion of the reaction process, the reactor was heated to solvent stripping temperature (60-68°C) in vented mode, and a mixture of methanol/methylacetate (4 kg) was flashed overhead and collected in the overhead receiver tank. Additional methanol (4 kg) was transferred to the reactor, and a second solvent stripping operation was conducted to remove a mixture of methanol/methylacetate (4 kg). Finally, a third solvent stripping operation was conducted to remove a mixture of methanol/methylacetate (6 kg). After completion of this solvent stripping process, acetic acid (0.04 kg) was added to the reaction concentrate, which was then transferred out of the reactor and analyzed via GC to confirm that the trans-esterification reaction was complete. Composition of the reaction concentrate was as follows: norbornene methanol 83percent, norbornene methyl acetate trace amounts, methanol 17percent and MeOAc trace amounts.The norbornene methanol reaction concentrate (6 kg) was then charged to a suitably equipped vacuum distillation system consisting of a still pot with electric heating mantle, distillation column with stainless steel structured packing (4 theoretical plates), reflux splitter, water cooled condenser, overhead condensate receiver, and vacuum pump. Still pot temperature was controlled by adjusting the heat input on the heating mantle, and system vacuum was controlled by adjusting vacuum pressure at the overhead receiver. The still pot was initially heated in fully vented mode until reflux conditions were established in the distillation column. The reflux splitter was then started at the desired reflux ratio and fractional distillation proceeded by periodically removing liquid fractions from the overhead receiver. GC analysis was used to determine composition of the overhead fractions. Still pot temperature, overhead receiver vacuum, and reflux ratio were adjusted as needed to affect composition of the overhead stream. Initial overheadfractions contained primarily methanol with trace amounts of methylacetate. After removal of these solvents, high purity norbornene methanol was then distilled overhead under the following conditions: overhead temperature (70-75 °C), vacuum (4-5 mm Hg), and reflux ratio (2:1). The distillation process was terminated once the majority of the product had been removed from the still pot. Approximately 90percent of the contained norbornene methanol in the starting mixture was recovered as high-purity (>99.8percent assay) product, with trace amount of norbornene methyl acetate ( The GC analysis was performed on an Ultra 1 (crosslinked methyl siloxane) column, 25 m, 0.2 mm ID, 0.33 μπι film. Initial Conditions: 70°C, hold 1.0 min.; Gradient Conditions: 70°C to 240°C 10°C /min.; Final Conditions: 240°C, hold 10.0 min. Injector: 200°C. Detector: 250°C (FID). GC retention times: NBMeOH 7.1-7.3 min., NBAMeOH 7.5-7.6 min., and NBMeOAc 8.8-8.9 min.

YieldReaction ConditionsOperation in experiment
80 %Chromat. at 220℃; for 4 h; Autoclave; High pressure Into a suitable high pressure tube reactor were placed allyl acetate and dicyclopentadiene (DCPD) at 4:1 molar ratio based on cyclopentadiene monomer, and heated in a hot oil bath maintained at 220°C, and maintained at that temperature for four hours. At the end of the reaction, the high pressure tube was removed from the bath and quenched in a wet ice bath. The tube was washed then with methanol and dichloromethane and weighed to verify that no leakage had occurred. The resultant crude monomer sample was analyzed by GC-MS, which showed about 7.5percent unreacted allyl acetate, 10percent exo-/endo-norbornene methanol, 82percent exo-/endo-norbornene methyl acetate and 0.6percent (l,2,3,4,4a,5,8,8a-octahydro-l,4:5,8-dimethanonaphthalen-2-yl)methanol. Fractional distillation of the crude mixture resulted in the isolation of norbomene methyl acetate of greater than > 99.6percent purity. The GC-MS analysis was performed on an Altech EC-5 column, 30 m, 0.25 mm ID, 0.25 μηι film; Inlet-F: 250, MS source: 230°C, electron ionization. The GC conditions used are as follows: Gradient: 45°C to 120°C at 10°C/min, then heat at 40°C/min to 300°C, hold 2 min at 300°C.
