디옥틸 프탈레이트 C화학적 특성, 용도, 생산

화학적 성질

Colorless liquid

물리적 성질

Clear, light colored, viscous, oily liquid with a slight odor

용도

Phthalate ester used as plasticizers and additives. Used in toxicology studies as well as risk assessment studies of food contamination that occurs via migration of phthalates into foodstuffs from food-contact materials (FCM).

일반 설명

A clear liquid with a mild odor. Slightly less dense than water and insoluble in water. Hence floats on water. Flash point 430°F. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. As a liquid, can easily penetrate the soil and contaminate groundwater and nearby streams. Eye contact may produce severe irritation and direct skin contact may produce mild irritation. Used in the manufacture of a variety of plastics and coating products.

공기와 물의 반응

Insoluble in water.

반응 프로필

DI-N-OCTYL PHTHALATE reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen may be generated by mixing with alkali metals and hydrides. Can generate electrostatic charges by swirling or pouring [Handling Chemicals Safely, 1980. p. 250].

건강위험

Produces no ill effects at normal temperatures but may give off irritating vapor at high temperature.

건강위험

The acute oral toxicity is very low. Inges tion may result in nausea, somnolence, hallucination, and lacrimation. In humans, sucheffects may be noted at a dose level of150–200 mg/kg. The recovery is prompt.The oral LD50 value in mice is in the range6500 mg/kg. Its irritant action on the skinand the eyes of rabbits was mild. Di-n-octylphthalate fed to mice at the 5% level in dietshowed no reproductive toxicity.

화재위험

Special Hazards of Combustion Products: None

Safety Profile

Mildly toxic by ingestion. Experimental teratogenic and reproductive effects. A skin and severe eye irritant. Used as a plasticizer. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.

Source

Detected in distilled water-soluble fractions of new and used motor oil at concentrations of 1.3 to 1.4 and 73 to 78 μg/L, respectively (Chen et al., 1994). May leach from plastic products (e.g., tubing, containers) used in laboratories during chemical analysis of aqueous samples.

환경귀착

Biological. o-Phthalic acid was tentatively identified as the major degradation product of di-noctyl phthalate produced by the bacterium Serratia marcescens (Mathur and Rouatt, 1975). When di-n-octyl phthalate was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum, no degradation was observed after 7 d. In a 21-d period, however, gradual adaptation did occur, resulting in 94 and 93% losses at concentrations of 5 and 10 mg/L, respectively (Tabak et al., 1981). In the presence of suspended natural populations from unpolluted aquatic systems, the second-order microbial transformation rate constant determined in the laboratory was reported to be 3.7 ± 0.6 x 10-13 L/organism?h (Steen, 1991).
Chemical/Physical. Under alkaline conditions, di-n-octyl phthalate will initially hydrolyze to noctyl hydrogen phthalate and 1-octanol. The monoester will undergo hydrolysis forming ophthalic acid and 1-octanol (Kollig, 1993). The hydrolysis half-life at pH 7 and 25 °C was estimated to be 107 yr (Ellington et al., 1988).
