катион марганца (+2): [2- (сульфидокарботиоиламино) этиламино] метандитиоат

Химические свойства

Maneb is a yellow powder or crystalline solid with a faint odor.

Возможный контакт

A potential danger to those involved in manufacture, formulation, and application of this broad spectrum dithiocarbamatefungicide. Some dithiocarbamates have been used as rubber components. DFG warns of danger of skin sensitization. The BPS Pesticide incident in West Helena, AK resulted in an explosion and death of three firemen. The burning of a 1000-lb sack of Azinphos Methyl or the flashing of Maneb which was present on the facility may have caused the explosion

Несовместимости

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, water. 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.

Утилизация отходов

Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. Maneb is unstable to moisture and is hydrolyzed by acids and hot water. It decomposes at about 100℃ but may spontaneously decompose vigorously when stored in bulk. Incineration is the preferred disposal means. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office
