   How accurate is the boiling point of citric acid?

   • In the case of aqueous solutions of citric acid, for temperatures above 100 °C, most of reported in the literature boiling points T b.p. ( m) have an accuracy sufficient only for engineering calculations. The Timmermans tabulation [ 70] includes only two sets of boiling points, but one set is worth to mention.

   What temperature does citric acid crystallize?

   • Citric acid monohydrate crystallizes from cold solutions and the crystals lose their hydration water if gently heated at 70–75 °C and melt in the range of 135–152 °C. Fast heating leads to dehydration at about 100 °C, melting at 153 °C and decomposition above 175 °C. Citric acid is deliquescent in wet air.
