디메틸 히드라진 화학적 특성, 용도, 생산

• 화학적 성질

  colourless or yellow hygroscopic liquid which fumes in air

• 용도

  1,2-Dimethylhydrazine (SDMH) unlike its analog 1,1- dimethylhydrazine (UDMH) is used only in small quantities as a research chemical. There are no known commercial uses, although it was evaluated as a high-energy rocket fuel. The material is a fuming, strongly alkaline, moderately volatile liquid.

• 정의

  ChEBI: A member of the class of hydrazines that is hydrazine in which one of the hydrogens attached to each nitrogen is replaced by a methyl group. A powerful DNA alkylating agent and carcinogen, it is used to induce colon cancer in laboratory rats and mice.

• 일반 설명

  A colorless liquid with an ammonia-like odor. Less dense than water. Flash point is 5°F. Contact irritate skin, eyes, and mucous membranes. Very toxic by ingestion, inhalation and skin absorption. Used to make photographic chemicals.

• 공기와 물의 반응

  Highly flammable. Fumes upon exposure to air . Soluble in water with evolution of heat.

• 반응 프로필

  1，2-Dimethyl hydrazine dissolves, swells, and disintegrates many plastics [USCG, 1999].

• 건강위험

  Breathing of vapor causes pulmonary irritation, delayed gastro-intestinal irritation, tremors, and convulsions. Contact with skin or mucous membranes causes chemical burns. Can be absorbed through skin to cause systemic intoxication and convulsions.

• Safety Profile

  Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Poison by ingestion, intraperitoneal, intravenous, subcutaneous, and intramuscular routes. Moderately toxic by inhalation. Human mutation data reported. A very dangerous fire hazard when exposedto heat, flame, or oxidizers. A hgh-energy propellant for liquid-fueled rockets. When heated to decomposition it emits toxic fumes of NOx

• Carcinogenicity

  SDMH is carcinogenic to mice, rats, and hamsters using a variety of exposure routes. Oral doses of 21 mg/kg for 11 weeks produced intestinal tumors in rats. A lower dose (3 mg/kg) in drinking water for 12 months produced liver hemangioendotheliomas.A number of these tumors were metastatic. Mice given doses of 60–90 mg/day in drinking water developed a variety of tumors including angiosarcomas and lung adenomas . Both oral administration and intraperitoneal injection increased lung adenomas in the A/J strain mouse. Hamsters also developed angiosarcomas, intestinal tumors, and liver tumors following average daily intakes of 160 mg in drinking water. An in-depth description of the uniqueness of the colonic tumors was presented.
