Abstract |
The oxidation of p-oxybenzylalcohol into p-oxybenzaldehyd was investigated. Many aromatic nitro compounds nitrobenzene, nitrophenols, chloronitrobenzenes, dinitrobenzenes, nitrobenzoic acids, and nitrobenzene sulfonic acids-were used as oxidizing reagents.
The alkali solution of p-oxybenzylalcohol and the aromatic nitro compound was heated under the reflux condenser about 3hrs, and the yield of p-oxybenzaldehyd estimated by the hydroxylamin method.
I came to the conclusions as follows:
1) Generally, the more negative the substituted radical of the aromatic nitro compound is, the higher the yield of p-oxybenzaldehyd.
2) Among o-, p-, and m-isomer, the last gave highest yield.
3) I considered D ((2) and Table 6) as a potency of activity of nitro radical, and could express the relation between D and log X (X: the yield of p-oxybenzaldehyd) with the linear equation (4).
