Also, the mixture of Urea to Cinnamic Acid with the ratio of 4:1 is observed to be the eutectic point because it has the lowest melting point starting at 96.1 C and although the range is broad (96.1-131.1 C) it is most likely due to using too much of the mixture requiring a loner amount of time to melt completely. The set of isomers designated as (2R,3R) & (2S,3S) has a melting point of 93.5 - 95 °C. Chem. Cinnamic acid has the formula C6H5CHCHCOOH and is an odorless white crystalline acid, which is slightly soluble in water. Linear Formula C 6 H 5 CH=CHCOOH .
