Coconut oil, also known as coconut oil, is a non-volatile oil extracted from coconut seeds. Soluble in dichloromethane and petroleum ether (boiling range 65-70℃), slightly soluble in ethanol and almost insoluble in water. Extracted from coconut meat (dry). Coconut meat (dry) contains 65%-74% oil and 4%-7% water. Coconut trees grow on the coast of tropical islands or continents.

The main producing areas in China are Hainan Province, Leizhou Peninsula, Yunnan Province and southern Taiwan Province Province. It can be seen from the above constants that compared with other oils and fats, it has great specificity. Coconut oil has high saponification value and low refractive index. Through this method, we can identify whether coconut oil is mixed with other oils, and even quantify it. This change is mainly caused by the fatty acid composition of coconut oil.

The saturated content of coconut oil fatty acid composition is above 90%, but its melting point is only 24-27 degrees, which is due to the high carbonic acid content. This is also the reason why the Polenske value and Reichert-Meissl value are high. The fatty acid composition of coconut oil can also explain why complete hydrogenation has little effect on the melting point of coconut oil (45. 1℃).
