What are volatile organic compounds？
The definition of the United States emphasizes whether it participates in photochemical reactions and does not limit the boiling point and initial boiling point of compounds. Compounds such as acetone and tetrachloroethylene that do not participate in atmospheric photochemical reactions are referred to as exempt solvents; The World Health Organization limits the boiling point or initial boiling point and does not emphasize whether it participates in photochemical reactions; The international standard ISO 4618/1-1998 and the German standard DIN55649-2000 do not emphasize whether it participates in photochemical reactions, nor do they limit its boiling point or initial boiling point. They only emphasize that it can evaporate on its own at room temperature and pressure.
