개요
Nonanoic acid , also called pelargonic acid, is an organic compound composed of a nine - carbon chain terminating in a carboxylic acid with structural formula CH3(CH2)7COOH. Nonanoic acid forms esters—nonanoates. It is a clear, oily liquid with an unpleasant, rancid odor. It is nearly insoluble in water, but very soluble in chloroform, ether, and hexane.Its refractive index is 1.4322. Its critical point is at 712 K ( 439 °C ) and 2.35 MPa.
화학적 성질
Nonanoic acid has a fatty, characteristic odor and a corresponding unpleasant taste. May be prepared by oxidation of methylnonyl ketone; by oxidation of oleic acid; or from heptyl iodide via malonic ester synthesis.출처
Nonanoic acid is a fatty acid which occurs naturally as esters in the oil of pelargonium. Synthetic esters, such as methyl nonanoate, are used as flavorings.Nonanoic acid is also used in the preparation of plasticizers and lacquers.
The derivative 4-nonanoylmorpholine is an ingredient in some pepper sprays.
The ammonium salt of nonanoic acid, ammonium nonanoate, is used as an herbicide.
용도
The primary uses of this acid are in organic synthesis and in the manufacture of lacquers, plastics, pharmaceuticals, synthetic odors and flavorings, gasoline additives, flotation agents, lubricants, and vinyl plasticizers. Nonanoic acid has found some use in pharmaceutical preparations and as a topical bactericide and fungicide. It is also used in herbicides.정의
ChEBI: A C9 straight-chain saturated fatty acid which occurs naturally as esters of the oil of pelargonium. Has antifungal properties, and is also used as a herbicide as well as in the preparation of plasticisers and lacquers.제조 방법
Nonanoic acid is produced by malonic ester synthesis, from Heptyl iodide.일반 설명
Nonanoic acid occurs naturally in Pelargonium L′Her. It one of the flavor constituents of cooked rice, acerola fruit, licorice and yogurt.농업용
Herbicide, Fungicide: Pelargonic acid occurs naturally in many plants and animals. It is used to control the growth of weeds and as a blossom thinner for apple and pear trees. It is also used as a food additive; as an ingredient in solutions used to commercially peel fruits and vegetables상품명

Poison by intravenous route. Moderately toxic by ingestion. A severe skin and eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.잠재적 노출
Pelargonic acid, a naturally occurring fatty acid herbicide/fungicide. It is used to control the growth of weeds and as a blossom thinner for apple and pear trees. It is also used as a food additive; as an ingredient in solutions used to commercially peel fruits and vegetables; in the manufacture of lacquers, plastics and pharmaceuticals.Purification Methods
Esterify the acid with ethylene glycol and distil the ester. (This removes dibasic acids as undistillable residues.) The acid is regenerated by hydrolysing the ester in the usual way and is distilled in vacuo. [Beilstein 2 IV 1018.]비 호환성
Heated vapors may form explosive mixture with air. May react violently with strong oxidizers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders or dust. Incompatible with strong bases and silver compounds; mixture with some silver compounds may form explosive salts of silver oxalate.폐기물 처리
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Contact a licensed disposal facility about surplus and non-recyclable solutions. Burn in a chemical incinerator equipped with an afterburner and scrubber. Extra care must be exercised as the material in an organic solvent is highly flammable. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.펠라곤산 준비 용품 및 원자재
