10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Freely sublimes even at room temperature.

10.3 Possibility of hazardous reactions

METHYL CARBAMATE is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

This intermediate /N-carbomethoxymethylimino phosphoryl chloride/ (or its ethyl homolog), produced during prepn of phosphoryl dichloride isocyanate from interaction of phosphorus pentachloride & methyl (or ethyl) carbamate, is unstable. Its decomposition to the required product may be violent or explosive unless moderated by the presence of a halogenated solvent.

10.6 Hazardous decomposition products

When heated to decomposition it emits toxic fumes of NOx.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Methyl carbamate, present at a concentration of 100 ppm, was degraded 19 and 18% after three days cultivation in water from the Mino River and Akashi Beach, Japan, respectively(1).

12.3 Bioaccumulative potential

An estimated BCF value of 0.19 was calculated for methyl carbamate(SRC), using a measured log Kow of -0.66(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of methyl carbamate is estimated as approximately 10(SRC), using a measured log Kow of -0.66(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that methyl carbamate is expected to have very high mobility in soil(SRC). Methyl carbamate adsorbs on Na+, Mg2+, Al3+, and Cu2+ montmorillonites which catalyze the hydrolysis of methyl carbamate when equilibrated at room temperature and 100% relative humidity(4).

12.5 Other adverse effects

no data available

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.
