This class of solvent currently includes acetone, dimethyl carbonate, methyl acetate, parachlorobenzotrifluoride (Oxsol 100), tert-Butyl acetate, and propylene carbonate. Volatile Organic Compounds are compounds that combine with nitrogen oxides found in the air, to form harmful smog (ozone) when they come in contact with sunlight. Most absorbers have removal efficiencies in excess of 90 Volatile Organic Compounds (VOC's) react with nitrogen oxides on hot summer days to form ozone (smog).
