1-옥텐 C화학적 특성, 용도, 생산

화학적 성질

colourless liquid

화학적 성질

Colorless, clear liquid; gasoline aroma.

물리적 성질

Clear, colorless, flammable liquid with a mild but unpleasant hydrocarbon odor. Based on a triangle bag odor method, an odor threshold concentration of 1.0 ppbv was reported by Nagata and Takeuchi (1990).

용도

Plasticizer; surfactants. Used as a comonomer in the production of high density polyethylene and linear low density polyethylene. Starting material for synthesis of a variety of compounds including nananoic acid.

정의

ChEBI: An octene with an unsaturation C-1.

Aroma threshold values

High strength odor; recommend smelling in a 1.00% solution or less.

일반 설명

A colorless liquid. Flash point 70°F. Insoluble in water and less dense (at about 6 lb / gal) than water. Hence floats on water. Vapors are heavier than air and may settle in depressions. Reported to biodegrade very slowly. Used in organic synthesis, surfactants, and plasticizers.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

1-OCTENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.

건강위험

Generally low toxicity. Mildly anesthetic at high vapor concentrations. May irritate eyes.

Source

Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996).

환경귀착

Biological. Biooxidation of 1-octene may occur yielding 7-octen-1-ol, which may oxidize to 7- octenoic acid (Dugan, 1972).
Photolytic. Atkinson and Carter (1984) reported a rate constant of 8.1 x 10-18 cm3/molecule?sec for the reaction of 1-octene and OH radicals in the atmosphere.
Chemical/Physical. The reaction of ozone and OH radicals with 1-octene was studied in a flexible outdoor Teflon chamber (Paulson and Seinfeld, 1992). 1-Octene reacted with ozone producing heptanal, a thermally stabilized C7 biradical, and hexane at yields of 80, 10, and 1%, respectively. With OH radicals, only 15% of 1-octene was converted to heptanal. In both reactions, the remaining compounds were tentatively identified as alkyl nitrates (Paulson and Seinfeld, 1977). Grosjean et al. (1996) investigated the atmospheric chemistry of 1-octene with ozone and an ozone-nitrogen oxide mixture under ambient conditions. The reaction of 1-octene and ozone in the dark yielded formaldehyde, hexanal, heptanal, cyclohexanone, and a compound tentatively identified as 2-oxoheptanal. The sunlight irradiation of 1-octene with ozone-nitrogen oxide yielded the following carbonyls: formaldehyde, acetaldehyde, propanal, 2-butanone, butanal, pentanal, glyoxal, hexanal, heptanal, and pentanal.
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.

Purification Methods

Distil 1-octene under nitrogen from sodium which removes water and peroxides. Peroxides can also be removed by percolation through dried, acid washed, alumina. Store it under N2, or Ar in the dark. [Strukul & Michelin J Am Chem Soc 107 7563 1985, Beilstein 1 H 221, 1 II 199, 1 IV 874.]
