Paraffin is a white or light yellow odorless solid consisting of high molecular carbohydrates, predominantly C2 0 to C3 2 alkanes. The molecular weight is 35 0 ~ 4 2 0 (the range depends on the technical level of paraffin). Melting point 46 ~ 68 ℃, ignition point 204 ℃. Insoluble in water and alcohol, in most organic solvents can be dissolved in varying degrees. 1 Materials and Methods 1 1 Toxicological Information 1 1 1 Acute
