TīmeklisDiscussion: In the first section of the lab, we successfully determined the partition coefficient through a liquid to liquid extraction. The partition coefficient was determined to be 4.5 as the benzoic acid in the organic layer was 40.9mg and the benzoic acid in the aqueous layer was 9.1mg. The literature melting point is reported to be 122°C. TīmeklisEthyl p-aminobenzoate (EPAB, C9H11O2N, CAS Registry No. 94-09-7) is a white crystal without smell and widely used in chemical and pharmaceutical industry. As an important local anesthetic, it is extremely effective in relieving pain caused by traumatic injury, skin ulcers, and burn. Ethyl 4-aminobenzoate.
