10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

10.3 Possibility of hazardous reactions

Highly flammableThe vapour is heavier than air and may travel along the ground; distant ignition possible.Organosulfides, such as DIMETHYL SULFIDE, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Dimethyl sulfide rapidly decomposes dibenzoyl peroxide explosively in the absence of solvent, [J. Org. Chem., 1972, 37, 2885]. The sulfide also decomposes xenon difluoride explosively at ambient temps, [J, Chem Soc., 1984, 2827]. Interaction of dimethyl sulfide and oxygen is explosive at 210°C and above, [Atmos. Environ., 1967, 1, 491-497]. A delayed explosion occurred in a system containing nitric acid, dimethyl sulfide, and 1, 4-dioxane, even with cooling with liquid nitrogen, [Chem. Abs., 1972, 76, 13515].

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Dimethyl sulfide was initially present in a wastewater/recycled sludge mixture at 150 (ug/kg)/(ug/L); following activated sludge treatment, effluent concns were below the detection limit(7). Radiolabeled-dimethyl sulfide added to the head space over 1 ml of freshwater lake sediment was metabolized to methane and carbon dioxide; 33 and 5% radiolabeled carbon was converted to methane and carbon dioxide, respectively, in 8 hours(2). No degradation of dimethyl sulfide occurred in sterilized (heat killed - 70°C, 1 hr) samples of sediment(2). Addition of dimethyl sulfide to various anoxic aquatic sediments (e.g. fresh water, estuarine, alkaline/hypersaline) stimulated methane production(3). The yield of methane from dimethyl sulfide typically ranged between 52-63%, although high concns of dimethyl sulfide inhibited methanogenesis in sediment from alkaline lakes(3). Metabolism resulted in appearance of methanethiol as a transient intermediate(3). Dimethyl sulfide was completely biodegraded in anoxic salt marsh sediments within 11 days with the production of methanethiol and methane(4). Biological consumption rates of dimethyl sulfide, in seawater samples collected in the eastern Pacific Ocean, ranged from 1.1 nM/day to 18.0 nM/day, giving turnover times of 0.6 to 4.6 days(5). The conversion efficiency from added dimethyl sulfide to methane of an algal mat and sediments obtained from a hypersaline pond was 11.2%(6).

12.3 Bioaccumulative potential

An estimated BCF of 3.2 was calculated in fish for dimethyl sulfide(SRC), using a water solubility of 22,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of dimethyl sulfide is estimated as 6.3(SRC), using a water solubility of 22,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dimethyl sulfide is expected to have very high mobility in soil.

12.5 Other adverse effects

no data available
