Cardanol - Unsaturated, Density 0.930 G/ml, Boiling Point 225â°c, Freezing Point <20â°c | Chemical Resistance, Durable Coatings, Renewable Source, Versatile Applications

Cardanol is a phenol obtained from anacardic acid, the main component of cashew nutshell liquid (CNSL), a byproduct of cashew nut processing. Cardanol finds use in the chemical industry in resins, coatings, frictional materials, and surfactants used as pigment dispersants for water-based inks. It is used to make phenalkamines, which are used as curing agents for the durable epoxy coatings used on concrete floors.[1] The name of the substance is derived by contraction from the genus Anacardium, which includes the cashew tree, Anacardium occidentale
The name cardanol is used for the decarboxylated derivatives obtained by thermal decomposition of any of the naturally occurring anacardic acids. This includes more than one compound because the composition of the side chain varies in its degree of unsaturation. Tri-unsaturated cardanol, the major component (41%) is shown below. The remaining cardanol is 34% mono-unsaturated, 22% bi-unsaturated, and 2% saturated.[4]

In terms of physical properties, cardanol is comparable to nonylphenol. Cardanol is hydrophobic and remains flexible and liquid at very low temperatures;[5] its freezing point is below a 20 A C, it has a density of 0.930 g/mL, and boils at 225 A C under reduced pressure (10
