Acetic Acid → 2-Methyl-4-methoxyaniline
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetic Acid | HCID 176 | — |
| Reactant | 2-Nitrotoluene | HCID 6944 | — |
| Solvent | Water | HCID 962 | — |
| Product | O-Toluidine | HCID 7242 | — |
| Product | 2-Methyl-4-methoxyaniline | HCID 7610 | 76.6% |
Reaction Steps
The same catalytic reduction reaction as in Example 1 was carried out except that o-nitrotoluene was used in an amount of 68.6 g (0.5 mole), and 68.6 g of glacial acetic acid was used instead of distilled water. The reaction required a period of 220 minutes with the absorption of 26.4 liters of hydrogen until its termination. The reaction solution was worked up in the same way as in Example 1 to give 9.0 g of o-toluidine and 53.1 g (yield 76.6%) of 2-methyl-4-methoxyaniline. The 2-methyl-4-methoxyaniline was found to have a purity of 99.0% by gas chromatography.
