Fire resistance is a key benefit to phenolic resin, because the material chars rather than burns. Char is a reaction where the molecules are changed to a carbon structure rather than burning away as ash. Resins that are exposed to extreme heat give off very few toxic fumes, making them usef...

John Hyatt chemically combined nitrocellulose with camphor to make plastic called celluloid which is used to make ping pong balls. Baekeland combined formaldehyde and phenol and heated it. He found that when this substance cooled, it hardened to form a strong plastic which we use for making auto...
Anisole is a potential source of biofuels made from cellulose-based compounds. It is mainly used as a substitute for phenol-rich compounds. Perfumes and Fragrances Due to its aromatic smell, anisole can be used to synthesize other aromatic compounds such as anethole. It is used as a food flav...
