Compare Volatility Stearic Acid Sucrose
On the Comparison of Volatility between Stearic Acid and Sucrose
On the properties of substances, volatility is one of them. Today, we will compare the volatility of stearic acid and sucrose. The two have different properties and special uses, and have their own functions in various fields.
Stearic acid is a saturated fatty acid, a white and greasy solid. Its molecular structure contains a long chain alkyl group, which makes the intermolecular force quite strong. And its polarity is weak, which has a great impact on volatility. Because of its large intermolecular attractive force, it takes a lot of energy to make it break free from the liquid phase and escape into the gas phase. Therefore, stearic acid has low volatility, and its volatilization is rarely seen at room temperature.
In contrast, sucrose is a disaccharide, formed by the condensation of glucose and fructose. Sucrose molecules have multiple hydroxyl groups with strong polarity. The presence of hydroxyl groups allows sucrose molecules to form hydrogen bonds, and the force of hydrogen bonds cannot be underestimated. However, compared with the force between long-chain alkyl groups of stearic acid, the force between sucrose molecules is different. Sucrose is more likely to interact with surrounding water molecules in the environment due to its hydrophilicity of hydroxyl groups. However, its volatility is not very high. Although its polarity is stronger than that of stearic acid, the hydrogen bond binding and molecules are relatively large, which also limits its volatilization.
According to common sense, the volatility depends on the molecular structure and the force between molecules. Stearic acid has a large attractive force between molecules due to long-chain alkyl groups, while sucrose affects volatilization due to hydrogen bonds and molecular properties. In general, the volatility of stearic acid is lower than that of sucrose. The intermolecular force of stearic acid is stronger, and it is more difficult to get rid of the liquid phase binding. Although sucrose has hydrogen bonds, its molecular polarity and structural characteristics make it more volatile than stearic acid. The comparison of the volatility of the two is meaningful in the chemical and food industries, which can help practitioners understand its properties and make good use of it to achieve the best effect.
