METAM-SODIUM DIHYDRATE ??

METAM-SODIUM DIHYDRATE C??? ??, ??, ??

??? ??

A yellow to nearly clear yellow-green solution. Also described as a colorless to white crystalline solid. Unpleasant sulfur-amine odor, similar to that of carbon disulfide

??

Metam-sodium Dihydrate is a soil fumigant that is widely used as a pesticide.

??? ??

A dithiocarbamate fungicide, nematicide, herbicide, soil fumigant, and algaecide A general soil biocide that is used to control weeds, weed seeds, roots, tubers, rhizomes, insects, nematodes and soil inhabiting fungi on all food and nonfood crops. Also used as a preplanting fumigant in seed beds, vine crops, fruit trees, row crops, flowers and ornamentals. Environmental friendly; it breaks down after two weeks into carbon dioxide, water, and sodium and sulfur in small amounts. A United States Environmental Protection Agency Restricted Use Pesticide (RUP).

UN3267 Corrosive liquid, basic, organic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required. UN2771 Dithiocarbamate and Thiocarbamate pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

Slow reaction upon dilution in water releasing toxic gases of hydrogen sulfide and methyl isothiocyanate. This reaction is accelerated by the addition of acid. May liberate toxic gas when in contact with acids. Combustible; vapors when heated or dust from dry material may form explosive mixture in air. Dithiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of Dithiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of dithiocarbamate with aldehydes, nitrides, and hydrides. Dithiocarbamate are incompatible with acids, peroxides, and acid halides. Corrosive to iron, copper brass and zinc metals, especially in the presence of moisture. Heat alkalies (lime), moisture can cause decomposition. Degradation produces ethylene thiourea.

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. A potential candidate for liquid injection incineration at a temperature range of 650 to 1600C and a residence time 0.1 to 2 seconds. Also, a potential candidate for rotary kiln incineration at a temperature range of 820 to 1600C and residence times of seconds for liquids and gases, and hours for solids.
