Does wood undergo pyrolysis before it burns?
Wood undergoes pyrolysis as it burns. Pyrolysis is the destructive distillation of the wood, producing gasses, which burn as they leave the wood, and carbon, which will also eventually burn. This is how wood normally burns.There is a link to an article on pyrolysis below.
What do carbon pyrolysis wood charbon briquettes have in common?
charcoal
What is the chemical process that causes the production of ignitable vapors from solid wood fuels?
Pyrolysis
What is the Chemical processes that causes that causes the production of ignitable vapors from solid wood?
Pyrolysis
Does wood undergo pyrolysis?
Yes, by dry heating without acces to air. One of the products -besides of charcoal- is ' spirit of wood' which is methanol, CH3OH. (toxic, blindness)
When wood burns is that sublimation?
No. Sublimation is a physical phase change in which a solid vaporizes without going through a liquid change. Sublimation does not involve a chemical change. Iodine sublimes, passing directly from solid to gas. Clearly, this is not what happens when wood burns. When wood burns, the first thing that happens is that the wood undergoes pyrolysis, which is decomposition resulting from heat, or destructive distillation. The wood decomposes into a number of gasses, including carbon monoxide, methanol, and a large number of other carbon based chemicals. These combine with air and oxidize, producing mostly carbon dioxide and water. After the initial pyrolysis, charcoal remains. This burns with air, producing carbon dioxide and ash. There are links below to articles on sublimation and pyrolysis.
What is guaiacol?
Guaiacol is a naturally occurring organic compound with the formula C6H4(OH)(OCH3). This colourless aromatic oil is derived from guaiacum or wood creosote. Samples darken upon exposure to air and light. Guaiacol is present in wood smoke, resulting from the pyrolysis of lignin Guaiacol is a naturally occurring organic compound with the formula C6H4(OH)(OCH3).

What is the cause of pyrolysis?
Pyrolysis is a chemical decomposition caused by heat. When a combustible material is exposed to high temperatures for a long time will dry out, break and can even burn.
