Carbolic soap Carbolic soap Carbolic soap is a mildly antiseptic soap containing carbolic acid and/or cresylic acid, both of which are phenols derived from either coal tar or petroleum sources. In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, now known as carbolic acid, which he derived in an impure form from coal tar. In August 1865, Dr. Joseph Lister, 1st Baron Lister applied a piece of lint dipped in carbolic acid solution onto the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg.

3-Nitrobenzoic acid 3-Nitrobenzoic acid 3-Nitrobenzoic acid is an organic compound with the formula CH(NO)COH. It is an aromatic compound and under standard conditions, it is an off-white solid. The two substituents are in a meta position with respect to each other, giving the alternative name of m-Nitrobenzoic acid. This compound can be useful as it is a precursor to 3-aminobenzoic acid, which is used to prepare some dyes. It is prepared by nitration of benzoic acid at low temperatures. Both 2-Nitrobenzoic acid and 4-Nitrobenzoic acid are produced as side products, with yields of approximately 20% and 1.5% respectively. Since carboxylic acid functional
