What is the best recrystallization solvent for cinnamic acid?
Water works well as recrystallization solvent for these two solids.
Is cinnamic acid a phenolic compound?
Phenolic acids are derivatives of benzoic and cinnamic acids and are present in all cereals. These acids exhibit high antioxidant activity in vitro and thus are beneficial for human health (Kamath et al., 2004). There are two classes of phenolic acids: hydroxybenzoic acids and hydroxycinnamic acids.
How do you recrystallize cinnamic acid?
Place the flask on a hotplate set to medium heat and stir the solution with a glass rod until the cinnamic acid dissolves, which usually takes 7 – 10 min. Then, turn off the heat and use a Pasteur pipette to add 5 drops of deionized water to the solution. This reduces cinnamic acid solubility.
Why alcohol is used in recrystallization?
Ethanol/water combinations are commonly used because ethanol has good dissolving ability for many organics, but is also infinitely co-soluble with water. Addition of water can rapidly and dramatically reduce the solubility of many organics and thus induce crystallization.
What is cinnamic acid?
Cinnamic acid is an organic compound with the formula C 6 H 5 CH=CHCOOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants.
