Benzoic acid melting point 0 °C and the pure was 119. ) Boiling point 170-172 °C/10 mmHg (lit. <link rel="stylesheet" href="/shop/styles. The experiment had two different sections with different goals in each. Benzoic acid CAS No. 4 degree Celsius. 0 and it is not recom- mended above ph 4. I have also learned that the longer carbon chains, the higher melting point due to the increase of the London dispersion forces. Therefore, benzoic acid is said to be an aromatic carboxylic acid.
