Carbamates

AMMONIUM CARBAMATE is a carbamate salt. 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. This compound is unstable in an alkaline media (NTP, 1992). Moderate fire and explosion hazards when exposed to heat or flame (USCG, 1999).

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Irritating to eyes, nose and throat.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

Method 417G: Automated Phenate Method for the determination of ammonia nitrogen. This method is used to determine ammonia concentrations in potable, surface, and Saline waters as well as domestic and industrial wastewaters over a range of 0.02 to 2.0 mg/liter. Photometric measurement is made at 630 to 660 nm. For ammonia concentrations of 1.41, 0.77, 0.59, and 0.43 mg/liter, the standard deviation was + 0.005 or -0.005. /Ammonia/|Method 417E Ammonia: Selective Electrode Method. This method is applicable for the measurement of 0.03 to 400 mg nitrogen ammonia/l in potable and surface waters and domestic and industrial wastes. The ammonia selective electrode uses a hydrophobic gas permeable membrane to separate the sample solution from an electrode internal solution of ammonium chloride. Ammonia diffuses through the membrane and changes the internal solution pH, which is sensed by a pH electrode. In an inter-laboratory study (12 laboratories) using effluent water samples at 0.04, 0.10, 0.80, 20, 100, and 750 mg/l, mean recovery was 100, 470, 105, 95, 97, and 99%, respectively. /Ammonia/|Method 417D: Titrimetric Method for the Determination of Ammonia Nitrogen. This method is applicable to ammonia concentrations in wastewater effluent greater than 5 mg/l. After distillation, the sample is titrated with 0.02 N sulfuric acid until a lavender color forms. For concentrations of 200, 800, and 1500 ug/l, relative standard deviation is 69.8, 28.6, and 21.6% respectively, and relative error is 20.0, 5.0, and 2.6%, respectively. /Ammonia/|Method 417C: Phenate Method for the Determination of Ammonia Nitrogen. This manual colorimetric technique is used to determine ammonia concentrations in wastewater effluent from 10 to 500 ug/l. The blue compound, indophenol, is formed by the reaction of ammonia, hypochlorite, and phenol catalyzed by a manganous salt. For ammonia concentrations of 200, 800, and 1500 ug/l, relative standard deviation is 39.2, 15.8, and 26.0%, respectively, and relative error is 2.4, 1.5, and 10.0%, respectively. /Ammonia/|For more Analytic Laboratory Methods (Complete) data for AMMONIUM CARBAMATE (7 total), please visit the HSDB record page.
