| | Bis(2-chloroethoxy)methane Usage And Synthesis |
| Description | Bis(2-chloroethoxy)methane is a colorlessliquid. Molecular weight=173.1; Boiling point=218℃;Freezing/Melting point=233℃; Flash point=110℃(oc). Hazard Identification (based on NFPA-704 M RatingSystem): Health 2, Flammability 1, Reactivity 0. Slight solubility in water; solubility=0.8%. | | Chemical Properties | Bis(2-chloroethoxy)methane is a colorless
liquid. | | Uses | Manufacture of insecticides, polymers; degreasing solvent; intermediate for polysulfide
rubber. | | Uses | Bis(2-chloroethoxy)methane is an chloroether used to manufacture polysulfide polymers. | | General Description | A colorless liquid. Boiling point 217.5°C, Flash point 230°F. Density 1.23 g / cm3. May be toxic by ingestion or inhalation. Severely irritates skin, eyes, and mucous membranes. Used as a solvent. | | Air & Water Reactions | Slightly soluble in water. | | 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. |
