Cardanol does not boil cleanly; its “boiling point” is often decomposition-limited. A high reported number may actually indicate measurement under non-equilibrium conditions or with oxidized impurities.
The saturation level of the C15 side chain influences the boiling point. Saturated chains (straight alkyl groups) generally pack more tightly and have slightly different volatilities compared to kinked, unsaturated chains. A batch with a higher percentage of tri-unsaturated components may exhibit a slightly different distillation curve than a batch dominated by mono-unsaturated components. cardanol boiling point
Ethoxylation or sulfonation reactions are exothermic. Designers must ensure that the heat of reaction does not push localized temperatures near the cardanol boiling point, which would cause loss of active material and hazardous vapor release. Cardanol does not boil cleanly; its “boiling point”
To understand the boiling point, one must first understand the molecule. Cardanol is not a single, uniform chemical entity like benzene or ethanol. Instead, it is a naturally occurring mixture of meta-alkylphenols. The typical composition of technical-grade cardanol includes: Saturated chains (straight alkyl groups) generally pack more
