化学的特性
Colorless liquid
物理的性質
Clear, light colored, viscous, oily liquid with a slight odor
使用
Di-n-octyl phthalate is used as a plasticizer for many resins and elastomers. It acts as an additive. It is also used for medical tubing and blood storage bags, wire and cables, carpet back coating, floor tile and in cosmetics.
一般的な説明
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.
空気と水の反応
Insoluble in water.
反応プロフィール
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].
健康ハザード
Produces no ill effects at normal temperatures but may give off irritating vapor at high temperature.
火災危険
Special Hazards of Combustion Products: None
安全性プロファイル
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.
環境運命予測
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).
