ABSTRACT

1,1’-Oxydi-2-propanol is one of the isomers found in commercial dipropylene glycol, and therefore, may be released at sites where dipropylene glycol is produced or used as a solvent and plasticizer. 1,1’-Oxydi-2-propanol has been detected in groundwater near a landfill. Bioconcentration in aquatic organisms and adsorption to sediment are not expected to be important environmental fate processes because 1,1’-oxydi-2-propanol is miscible in water. Aquatic hydrolysis and volatilization are also not expected to be important. Vapor-phase 1,1’-oxydi-2-propanol is expected to degrade readily in an average ambient atmosphere (estimated half-life of about 13 hr) by reaction with photochemically produced hydroxyl radicals. 1,1'-Oxydi-2-propanol's miscibility in water suggests that physical removal from air via wet deposition is possible. 1,1’-Oxydi-2-propanol is completely miscible in water which suggests that bioconcentration in aquatic organisms will not be important. 1,1’-Oxydi-2-propanol is completely miscible in water which indicates that the compound will be readily mobile in soil.
