Simply so, is caffeine polar in ethyl acetate?

Ethyl acetate is a polar molecule, which makes it a good solvent for capturing the polar caffeine molecules from the coffee beans (since 'like dissolves like'). This method decaffeinates the coffee beans by approximately 97%.

Also, is caffeine soluble in methylene chloride? Caffeine is more soluble in methylene chloride than water because both caffeine and methylene chloride are organic substances while water is inorganic. Although caffeine is capable of dissolving in water by forming hydrogen bonds, the greater affinity that caffeine has for methylene chloride breaks these bonds.

Hereof, what is caffeine soluble in?

1. Caffeine is also soluble in water (approx. 16 mg/ml at room temperature, 200 mg/ml at 80°C, or 666 mg/ml in boiling water. Solubility in water is increased by adding dilute acid (e.g. HCl or citric acid).

Is caffeine soluble in oil?

Caffeine solubility in water is temperature dependant. However at room temperature caffeine is about 6 times more soluble in dichloromethane than in water.
