Cardanol is a natural phenolic compound extracted from cashew nut shell liquid, with a unique chemical structure and wide application value. It is liquid at room temperature and has both phenolic and long-chain alkyl characteristics. It is often used in environmentally friendly coatings, resin modification, pharmaceutical synthesis and other fields. It is regarded as a green alternative to traditional petrochemical products due to its renewability and low toxicity.

Source and preparation：

Cardanol is mainly derived from cashew nut shell liquid, a byproduct of cashew processing, and is extracted through processes such as distillation and extraction.

Its molecular structure contains phenolic hydroxyl groups and 15-carbon alkyl side chains, which have both polar and non-polar characteristics.

Features and advantages：

Strong stability, high temperature resistance, oxidation resistance, and stable performance in acidic or alkaline environments.

It has wide compatibility and can be combined with materials such as epoxy resin and polyurethane to improve flexibility and adhesion.

It has outstanding environmental protection. Compared with petrochemical raw materials such as phenol, it has low production energy consumption and better biodegradability.

Main application areas：

Industrial materials: used to manufacture anti-corrosion coatings, friction materials, rubber plasticizers, and improve product weather resistance and mechanical strength.

As an epoxy resin curing agent, it reduces the brittleness of materials and reduces environmental pollution.

Medicine and daily chemicals: Some studies have shown that it has antibacterial and anti-inflammatory activities, and may be used in drug intermediates or skin care products (further clinical verification is required).

Replace alkylphenols when synthesizing surfactants to reduce the risk of ecotoxicity.

Precautions:

Wear protective gloves when contacting cardanol and avoid direct contact with skin or eyes.

Store in a cool and ventilated place, away from fire and strong oxidants.

If used in pharmaceutical-related products, laboratory specifications must be strictly followed, and related preparations must be used under the guidance of a doctor. If allergic reactions occur, stop using immediately and seek medical attention.
