eptanoic acid Usage And Synthesis
DescriptionAs an organic compound, heptanoic acid is a seven-carbon linear chain saturated fatty acid with an unpleasant, rancid and pungent odor, which is commonly used as a chemical intermediate in the synthesis of esters for products, such as ethyl heptanoate, that are used in fragrances and artificial flavors. It is also applied in cosmetics for the production of emollients, skin conditioning agents as well as viscosity controlling agents. Besides, heptanoic acid can also act as a industrial lubricant applied in the fields of aviation, refrigeration, automobile, etc. due to its low viscosity at low temperature and low volatility at high temperature. Moreover, the good anti-corrosion property of heptanoic acid results in the usage of metalworking fluids, industrial water-based refrigerants and anti-corrosion additive for paint. Heptanoic acid is also applied to esterify steroids in the field of pharmaceutical to produce drugs such as testosterone enanthate, trenbolone enanthate, drostanolone enanthate, methenolone enanthate and it is also one of numerous additives in cigarettes.
DescriptionHeptanoic acid, also called enanthic acid, is an organic compound composed of a seven - carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant, rancid odor. It contributes to the odor of some rancid oils. It is slightly soluble in water, but very soluble in ethanol and ether.
Chemical PropertiesHeptanoic acid has a disagreeable rancid odor. The spectroscopically pure acid exhibits a faint tallow-like odor. Heptanoic acid may be prepared by oxidation of heptaldehyde with potassium permanganate in diluted sulfuric acid.
Chemical PropertiesHeptanoic acid has a disagreeable rancid, sour, sweat-like, fatty odor The spectroscopically pure acid exhibits a faint fallow-like odor.
Chemical Propertiescolourless liquid with a pungent and rancid odour
OccurrenceReported as occurring naturally in calamus, hops, Acacia dealbata, and Japanese peppermint and violet leaves; its presence in rancid oils has been observed Also reported found in passion fruit, mandarin orange peel oil, guava, apple, banana, grapes, papaya, raspberry, strawberry, kiwi, baked potato, sauerkraut, tomato, breads, cheeses, butter, milk, fsh, fsh oil, meats, chicken fat, pork fat, hop oil, beer, cognac, brandy, rum, grape wines, sherry, whiskies, sake, peated malt, cocoa, coffee, tea, soy protein, peanuts, pecans, coconut, beans, mushroom, fenugreek, mango, fgs, licorice, corn oil, shrimps, scallops and other sources
UsesIntermediates of Liquid Crystals
UsesThere are two major uses for heptanoic acid. One is in vinyl plasticizers that are used primarily in the automotive market.This market is expected to grow 3 to 4% per year with GNP.The second is in synthetic lubricants, where heptanoic acid is used in polyol esters.The market for polyol esters is primarily for use in commercial and military jet turbine lubricants.There is a small market for these esters in the automotive lubricant area, but there has been limited acceptance of these products by automakers and the public.The growth of the polyol ester market is expected to track GNP, unless automakers change to support synthetics or unless there is an elevation of military activity.
The use of heptanoic acid in high-water metalworking fluids has grown in excess of 20% over the last several years.The amount of acid used in these products is small; therefore, a dramatic change from the traditional oil-based fluids would be required before there would be significant market impact.
DefinitionChEBI: A C7, straight-chain fatty acid that contributes to the odour of some rancid oils. Used in the preparation of esters for the fragrance industry, and as an additive in cigarettes.
Production MethodsThe methyl ester of ricinoleic acid, obtained from castor bean oil is the main commercial precursor to heptanoic acid. It is hydrolyzed to the methyl ester of [[undecenoic acid]] and heptanal, which is then air oxidized to the carboxylic acid. Approximately 20,000 tons were consumed in Europe and US in 1980.
Ricinoleic acid is the main precursor to heptanoic acid. Heptanoic acid is used in the preparation of esters, such as ethyl heptanoate, which are used in fragrances and as artificial flavors. Heptanoic acid is used to esterify steroids in the preparation of drugs such as as testosterone enanthate, trenbolone enanthate, drostanolone enanthate and methenolone enanthate (Primobolan). It is also one of many additives in cigarettes.
