Preparation of 3-iodopropionic acid

Preparation of 3-iodopropionic acid

100 g of phosphorus diiodide (P2I4) are added in small quantities to 52 ml of glyceric acid in a large round flask, and the mixture gently heated till a violent reaction sets in. Should it become too violent the flask is cooled in water. The product, a dark brown syrupy liquid, is again heated, when a second less violent reaction occurs. A light yellow liquid, which, on cooling, solidifies to a crystalline mass, is formed. From this, 3-iodopropionic acid is extracted with hot carbon disulphide or petroleum ether. The solvent is distilled off and the discoloured residue recrystallised from carbon disulphide or petroleum ether. 3-Iodopropionic acid forms colourless crystals, slightly soluble in cold, readily in hot water and in alcohol; m.p. 83.5° C.
