N-NITROSODI-N-PROPYLAMINE

Химические свойства

N-nitrosodi-N-propylamine is a yellow liquid.

Использование

N-Nitrosodi-n-propylamine is used in small quantities in laboratory research. It has no known commercial use (IARC 1978, ATSDR 1989, HSDB 2009).

Общее описание

Clear to pale yellow liquid.

Профиль реактивности

N-NITROSODI-N-PROPYLAMINE is a nitrated amine derivative. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Угроза здоровью

ACUTE/CHRONIC HAZARDS: Toxic.

Пожароопасность

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Профиль безопасности

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic data. Moderately toxic by ingestion and subcutaneous routes. An experimental teratogen. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also NITROSAMINES.

Возможный контакт

N-nitrosodi-N-propylamine is used in the manufacture of plastics, resins, rubber, and synthetic textiles. There is no evidence that N-nitrosodi-N-propylamine exists naturally in soil, air, food, or water. Small quantities of N-nitrosodi-N-propylamine are inadvertently produced during some manufacturing processes; as an impurity in some commercially available dinitroaniline based weed killers, and during the manufacture of some rubber products. However, according to Sax, some similar N-nitroso compounds are formed in the environment and absorbed from precursors in food, water, or air; from tobacco; and from naturally occurring compounds.

Канцерогенность

N-Nitrosodi-n-propylamine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Экологическая судьба

Chemical/Physical. N-Nitroso-n-propylamine will not hydrolyze because it does not contain a hydrolyzable functional group (Kollig, 1993).
At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities were 24, 13, 7.4, and 4.0 mg/g, respectively (Dobbs and Cohen, 1980).

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. Sensitive to UV light.

Утилизация отходов

N-Nitrosodi-N-propylamine may be destroyed by high temperature incineration in an incinerator equipped with an nitrogen oxide scrubber. Chemical treatment methods may also be used to destroy N-nitrosodi-N-propylamine. These methods involve (a) denitrosation by reaction with 3% hydrobromic acid in glacial acetic acid; (b) oxidation by reaction with potassium permanganate-sulfuric acid; or (c) extraction of the nitrosamine from the waste using dichloromethane and subsequent reaction with triethyloxonium tetrafluoroborate (TOEF). Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
