Propionitrile

CAS RN:107-12-0

Disposal Methods

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P101 must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
A good candidate for liquid injection incineration at a temperature range of 650 to 1,600 deg C and a residence time of 0.1 to 2 seconds. Also, a good candidate for rotary kiln incineration at a temperature range of 820 to 1600 deg C and residence times of seconds for liquids and gases, and hours for solids. Also, a good candidate for fluidized bed incineration at a temperature range of 450 to 980 deg C and residence times of seconds for liquids and gases, and longer for solids.
The following wastewater treatment technology has been investigated for propionitrile: Concentration process: Biological treatment.
Treatment and Disposal Method: Recommendable: Incineration, alkaline hydrolysis, oxidation, discharge to sewer. Not recommendable: Evaporation. Add by stirring excessive sodium hydroxide. After one hour, evaporate alcohol and add sufficient calcium hypochlorite. After 24 hours, drain into a sewer with abundant water. Peer review: Incinerate in a unit with effluent gas scrubbing.
