The high boiling point and low vapor pressure of cardanol make it an ideal "green" alternative to petroleum-based phenols like nonylphenol. Cardanol (C15:1) | CAS#:501-26-8 | Chemsrc
The Clausius–Clapeyron relationship applies. For cardanol (est. molar mass ~300–350 g/mol), reducing pressure from 760 mmHg to 10 mmHg lowers the boiling point by approximately 50–70°C. This is why all commercial distillation of CNSL derivatives occurs under vacuum. cardanol boiling point
When incorporating cardanol into formulations or distillation processes, always consult the congener analysis and distillation curve from your supplier. Design equipment with generous temperature margins, inert gas purging, and pressure relief to accommodate the complex boiling behavior of this valuable bio-based material.
