Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of different ty… WitrynaParaffin is a name that is commonly used to denote a group of saturated alkane hydrocarbons with the general formula C n H 2n+2, where “n” is greater than 20. They take both solid and liquid forms. The solid form known as paraffin wax was discovered by Karl Reichenbach in 1830.
