Возможный контакт
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.
Экологическая судьба
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).

Несовместимости
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.
Утилизация отходов
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.
