10.2 Chemical stability

In the absence of moisture at ordinary temp, dichloromethane is relatively stable when compared with its congeners, chloroform and carbon tetrachloride.

10.3 Possibility of hazardous reactions

It is flammable in the range of 12-19% in air but ignition is difficult.The vapour is heavier than air. As a result of flow, agitation, etc., electrostatic charges can be generated.DICHLOROMETHANE reacts vigorously with active metals such as lithium, sodium and potassium, and with strong bases such as potassium tert-butoxide. It is incompatible with strong oxidizers, strong caustics and chemically active metals such as aluminum or magnesium powders. The liquid will attack some forms of plastic, rubber and coatings. This compound reacts with sodium-potassium alloy, (potassium hydrogen + N-methyl-N-nitrosurea), nitrogen tetraoxide and liquid oxygen. It also reacts with titanium. On contact with water it corrodes iron, some stainless steels, copper and nickel. It is incompatible with alkali metals. It is incompatible with amines, zinc and alloys of aluminum, magnesium and zinc. This compound is liable to explode when mixed with dinitrogen pentaoxide or nitric acid. Mixtures of this compound in air with methanol vapor are flammable.

12.2 Persistence and degradability

AEROBIC: Dichloromethane is reported to completely biodegrade under aerobic conditions with sewage seed or activated sludge between 6 hours to 7 days(1-5). Dichloromethane, present at 100 mg/L, reached 13% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test (OECD 301C Method)(6). Using a respirometer test method, 49% of initial dichloromethane (10 mg/L) biodegraded using an adapted activated sludge inoculum(7). Using a Sapromat respirometer test method, nearly 100% of initial dichloromethane (660 mg/L) biodegraded using an adapted sewage inoculum(7). Dichloromethane was degraded at a concentration of 3.3 mg/L in the aqueous phase of natural sediment with a corresponding half-life of 10.9 days(8). Dichloromethane, at 50 mg/L, had 0% degradation in a Manometric respirometry test over a 28-day incubation period(9).

12.3 Bioaccumulative potential

Using carp (Cyprinus carpio) which were exposed over a 6-week period, a BCF range of 2.0-40 was determined for dichloromethane at initial concentrations of 25 and 250 ug/L(1). According to a classification scheme(2), this BCF range suggests bioconcentration in aquatic organisms is low to moderate(SRC).

12.4 Mobility in soil

Dichloromethane has reported experimentally derived Koc values of 28(1), 36(2), 48 and 8(3). According to a classification scheme(4), these Koc values suggest that dichloromethane is expected to have very high mobility in soil. Dichloromethane is adsorbed strongly to peat moss, less strongly to clay, only slightly to dolomite limestone, and not at all to sand(5).

12.5 Other adverse effects

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
