Benzoic acid synthesis

15synthesis methods
By oxidation of toluene with nitric acid or sodium bichromate or from benzonitrile.
-

Yield:65-85-0 99%

Reaction Conditions:

with oxygen;copper(II) nitrate in acetonitrile at 120; under 4500.45 Torr; for 10 h;

Steps:

35 Example 35

In a 15 mL PTFE-lined reactor, 0.1 mmol of 2-(2-methoxy)phenoxy-1-phenylethanone was added, 0.02 mmol of copper nitrate was weighed as a catalyst, and 2 mL of solvent acetonitrile was added. (substrate concentration is 0.05mol/L),The oxygen pressure is increased to 0.6 MPa, the temperature is raised to 120 ° C, and the reaction is stirred for 10 hours. After the reaction is completed,The product was detected by gas chromatography-mass spectrometry and the mass spectrum of the product benzoic acid and phenol was consistent with the standard mass spectrum.The chromatographically quantified substrate conversion and the yield of the product benzoic acid are shown in Table 1.
