Volatile organic compound - Wikipedia

2019-4-23 · Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature.Their high vapor pressure results from a low boiling point, which causes large nuers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility.For example, formaldehyde, which evaporates from
