Diethyl Ether

CAS RN:60-29-7

Disposal Methods

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U117, F003, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
Diethyl ether is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration. If concentrated waste contains no peroxides, discharge liquid at a controlled rate near a pilot flame. If concentrated waste contains peroxides, perforation of a container of the waste from a safe distance is followed by open burning.
A good candidate for liquid injection incineration at a temperture range of 650 to 1,600 deg C and a residence time 0.1 to 2 seconds. Also, a good candidate for rotary kiln incineration at a temperature range of 820 to 1,600 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.
This compound should be susceptible to removal from waste water by air stripping.
The limitations and feasibility of the land disposal of solid wastes containing organic solvents and refrigerants were investigated by evaluating the attenuation capacity of a hypothetical waste disposal site by numerical modeling. The basic theorem of this approach was that the land disposal of wastes would be environmentally acceptable if subsurface attenuation reduced groundwater concentrations of organic compounds to concentrations that were less than health based water quality criteria. Computer simulations indicated that the predicted concentrations of 13 of 33 organic compounds in groundwater would be less than their health based criteria. Hence solid wastes containing these compounds, which included diethyl ether, could be safely disposed at the site.
Incineration & evaporation: Scrap ethyl ether can be burned in an approved incinerator. Alternatively, small amt (adsorbed on vermiculite) can be disposed of by evaporation in a hood.
The following wastewater treatment technologies have been investigated for diethyl ether: Concentration process: Reverse osmosis.
Used ether containers, which are suspected of containing ether crystals or solids, are especially hazrdous and may require bomb-squad assistance for their disposal. /Short alkyl-chain ethers/
