Salicylic Acid Synthesis and Utilization. Kevin . McGovney. Aurion. . Farhadi. Nicholas Bean. Purpose: Synthesize Salicylic Acid Using the Kolbe-Schmitt Reaction. Kolbe-Schmitt Reaction: Was first successfully carried out in 1860 by a German chemist named Hermann Kolbe, by heating a mixture of phenol and sodium hydroxide in the presence of carbon dioxide at high pressure. . Therapeutic uses & contraindication. Aspirin . act as an analgesic, antipyretic, Anti-inflammatory also inhibit platelet aggregation & prolongs bleeding time, because of its effect on G.I.T it is contraindicated in peptic . Theory: . salicylic acid is prepared from methyl salicylate by hydrolysis of ester group with aqueous alkali (NaOH or KOH). Salicylic acid is a . monohydroxybenzoic. acid, a type of phenolic acid and a beta hydroxy acid. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of . Learning Objectives :. 1. Know the groups of . a.a. . biosynthetic families. 2. The enzymes and coenzymes involved in the synthetic pathways. 3. The enzyme deficiencies of each pathway.. 4. The consequences of the inborn errors of metabolism. 2. Aged proteins, damaged or modified proteins and non-functional proteins of the body undergo degradation. . 3. Protein degradation may play important role in shaping tissues and organs during pregnancy and development.. 3. Surface Active Agents. Done by :. Hiba. Sabah . Sura. . Alkazzaz. Nora . Zawar. introduction. Surface-active . agents . or . surfactants. are molecules and ions that are adsorbed at interfaces. Surfactants are materials that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. An alternative term is . Internally , although it shows antipyretic and analgesic activities, its salts and derivatives are used for these purposes.. There are two types of derivatives of SA depends upon the attack on which group takes place:.
