Reactivity Profile

Bis(2-chloroethoxy)methane, the b-chloroethyl acetal of formaldehyde, is incompatible with oxidizing agents.

Health Hazard

ACUTE/CHRONIC HAZARDS: Toxic by inhalation and ingestion; Strong irritant.

Fire Hazard

Not Flammable.

Potential Exposure

The chloroalkyl ethers have a wide variety of industrial uses in organic synthesis, treatment of textiles; the manufacture of polymers; polysulfide rubbers, and insecticides; as degreasing agents and solvents; and in the preparation of ion exchange resins.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least 15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

Environmental Fate

Biological. Using settled domestic wastewater inoculum, bis(2-chloroethoxy)methane (5 and 10 mg/L) did not degrade after 28 d of incubation at 25 °C (Tabak et al., 1981).
Chemical/Physical. At influent concentrations of 10, 1.0, 0.1, and 0.01 mg/L, the GAC adsorption capacities were 50, 11, 2.6, and 0.6 mg/g, respectively (Dobbs and Cohen, 1980).

storage

Color Code—Green: General storage may be used.Store in tightly closed containers in a cool, well-ventilatedarea away from oxidizers. Sources of ignition, such assmoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could createa potential fire or explosion hazard.

Shipping

UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required.

Incompatibilities

The aqueous solution is a strong acid; keep away from bases and alkaline material. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact with mineral acids causes decomposition.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Destroy by high-temperature incineration with HCl scrubber.
