옥틸알데히드 C화학적 특성, 용도, 생산

개요

May be prepared by oxidation of the corresponding alcohol or reduction of the corresponding acid; also from coconut fatty acids via methyl-n-octanoate.

화학적 성질

n-Octanal has a fatty, citrus, honey odor on dilution.

화학적 성질

liquid

화학적 성질

Octanal occurs in several citrus oils, for example, orange oil. It is a colorless liquid with a pungent odor, which becomes citrus-like on dilution. Octanal is used in perfumery in low concentrations, in eau de cologne, and in artificial citrus oils.

출처

Reported found in the essential oils of sweet orange, bitter orange, mandarin, tangerine, grapefruit, Mexican lime, lemon, Taiwan citronella, rose, lemongrass, Pinus sabiniana, Pinus jefferyi, Xanthoxylum rhetsa, lime petitgrain, clary sage, lavandin, and others. Also reported in over 180 foods and beverages including apple, apricot, many berries, guava, grapes, melon, papaya, celery, peas, potato, potato chips, tomato, ginger, spearmint oil, cheeses, butter, milk, cooked egg, fish and fish oil, meats, hop oil, beer, rum, cider, white wine, cocoa, tea, roasted filberts and peanuts, pecans, oats, coconut products, soybean, avocado, passion fruit, starfruit, beans, mushroom, trassi, macadamia nut, sesame seed, mango, cauliflower, tamarind, fig, calamus, rice, sweet potato, dill, lovage, caraway seed, corn oil, corn tortillas, loquat, shrimp, lobster, oyster, crab, crayfish, clam, maté, angelica root oil and mastic gum oil.

제조 방법

By oxidation of the corresponding alcohol or reduction of the corresponding acid; also from coconut fatty acids via methyl-n-octoate.

정의

ChEBI: A fatty aldehyde formally arising from reduction of the carboxy group of caprylic acid (octanoic acid).

Aroma threshold values

Detection: 1.4 to 6.4 ppb

Taste threshold values

Taste characteristics at 25 ppm: aldehyde, green with a peely, citrus, orange note.

일반 설명

Colorless liquids with a strong fruity odor. Less dense than water and insoluble in water. Flash points 125°F. Used in making perfumes and flavorings.

공기와 물의 반응

Flammable. Insoluble in water.

반응 프로필

OCTYL ALDEHYDES are aldehydes. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.

건강위험

Inhalation may be irritating to mucous membrane; overexposure may cause dizziness and collapse. Ingestion causes irritation of mouth and stomach. Contact with eyes or skin causes irritation.

화재위험

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Safety Profile

Mildly toxic by ingestion and skin contact. A skin and eye irritant. Flammable liquid when exposed to heat, sparks, or flame. Can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. See also ALDEHYDES.
