The deactivating substituents remove electron density, stabilizes the negative charge of the carboxylate anion, and increasing the acidity of the carboxylic acid. The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds The information in CAMEO Chemicals comes from a variety of data sources. Para-amino benzoic 5. kastatic. The ortho substituent may force the carboxyl group out of the plane of the benzene ring, thus decreasing the Such products are particularly useful when the nitrobenzoic acid is p-nitrobenzoic acid because they can be reduced in known manner to mixtures of glycerol mono- and di-para-aminobenzoates containing a very high proportion of the mono-aminobenzoate, which mixtures constitute excellent sun-screening agents. 47.
