2,6-Dimethyl-4-heptanone Chemical Properties,Uses,Production

Description

2, 6-Dimethyl-4-heptanone, also known as diisobutyl ketone, belongs to the family of ketones, being a flavoring ingredient. It can also be used as the extraction solvent for the determination of ten trace metals (V, Cr, Fe, Co, Ni, Cu, Zn, Mo, Cd, Pb) in aqueous samples with plasma atomic emission spectrometry. Similar logic can also be applied to the measurement of phosphorus using 2, 6-dimethyl-4-heptanone as the extraction agent. It is also an important organic solvent widely used as industrial intermediates.

Chemical Properties

5-Methyl-3-heptanone is a colorless liquid with low solubility in water (0.3 wt %); water is poorly soluble in the ketone (0.9 wt %). 5-Methyl-3-heptanone is highly soluble in common organic solvents.

Physical properties

Clear, colorless liquid with a mild, sweet, ether-like odor. Odor threshold concentration is 0.11 ppm (quoted, Amoore and Hautala, 1983).

Occurrence

Reported found in baked potato and wheaten bread.

Uses

Diisobutyl ketone is used as a solvent fornitrocellulose, lacquers, and synthetic resins;in organic syntheses.

Uses

2,6-Dimethyl-4-heptanone is used as a coating solvent. It is an active component of mint oil. It acts as a dispersant for organosol type resins. It is involved in the antigerminative treatment of bulbs and tubers. Further, it is used as a solvent for nitrocellulose. In addition to this, it acts as an intermediate in the preparation of inhibitors, active pharmaceutical ingredients and dyes.

Uses

Diisobutyl ketone (DIBK) is a transparent liquid with a distinct odor and a high boiling point. It is an heavy-end byproduct of producing MIBK. DIBK is used in many applications such as nitrocellulose lacquers, synthetic resins, coatings and stains, paint strippers, leather finishings, adhesives, printing and coating inks, cleaning and dregreasing, Flavors and fragrances, solvent and re-crystallization aid for pharmaceuticals, mining, and as a chemical intermediate. DIBK has good activity for many synthetic resins including nitrocellulose, rosin esters, phenolics, hydrocarbons, alkyds, polyesters, and acrylics. It is useful as a retarder solvent to improve flow and minimize humidity blushing. The low density and low surface tension of DIBK enables formulators to develop high-solids coatings with low VOC content and excellent flow and leveling properties. DIBK has excellent viscosity reduction for and reduces surface tension in high solid’s coatings. It has good volume-to-weight advantage over other classes of solvents used in coatings. It is a non-HAP (Hazardous Air Pollutant) solvent.

Uses

Diisobutyl Ketone is a component of mint oil and L-carvone solutions for fungicidal and antigerminative treatment of bulbs and tubers.

Definition

ChEBI: 2-Methyl-4-heptanone is a ketone.

Production Methods

Diisobutyl ketone is produced by hydrogenation of phorone or by metal-catalyzed decomposition of isovaleric acid.It is also a by-product in the manufacture of methyl isobutyl ketone.

General Description

A clear colorless liquid. Flash point 140°F. Less dense than water and insoluble in water. Vapors heavier than air.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

2,6-Dimethyl-4-heptanone may attack some plastics. 2,6-Dimethyl-4-heptanone reacts with oxidizers.

Health Hazard

Inhalation of vapor causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Vaporirritates eyes. Contact with liquid irritates skin.

Health Hazard

Inhalation of the vapors of diisobutyl ketonecan produce irritation of the eyes, nose, andthroat. At 25 ppm its odor was unpleasant, but the irritation effect on humanswas insignificant. At 50 ppm the irritationwas mild. A 7- hour exposure to 125 ppmhad no adverse effect on rats; however, at250 ppm, female rats developed increasedliver and kidney weights. An 8-hour exposure to 2000 ppm was lethal. Ingestion ofthis compound can cause the symptoms ofheadache, dizziness, and dermatitis.

Potential Exposure

Human Data;Primary Irritant. Diisobutyl ketone is used as a solvent; as a dispersant for resins; and as an intermediate in the synthesisof pharmaceuticals and pesticides.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the

Environmental Fate

Biological. Using the BOD technique to measure biodegradation, the mean 5-d BOD value (mM BOD/mM diisobutyl ketone) and ThOD were 4.86 and 37.4%, respectively (Vaishnav et al., 1987).
Chemical/Physical. Diisobutyl ketone will not hydrolyze because it has no hydrolyzable functional group.
At an influent concentration of 300 mg/L, treatment with GAC resulted in nondetectable concentrations in the effluent. The adsorbability of the carbon used was 60 mg/g carbon (Guisti et al., 1974).

storage

Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials. Prior to working with DIBK you should be trained on itsproper handling and storage. Before entering confined spacewhere DIBK may be present, check to make sure that anexplosive concentration does not exist. Store in tightlyclosed containers in a cool, well-ventilated area. Metal containers involving the transfer of this chemical should begrounded and bonded. Where possible, automatically pumpliquid from drums or other storage containers to processcontainers. Drums must be equipped with self-closingvalves, pressure vacuum bungs, and flame arresters. Useonly nonsparking tools and equipment, especially whenopening and closing containers of this chemical. Sources ofignition, such as smoking and open flames, are prohibitedwhere this chemical is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard.Wherever this chemical is used, handled, manufactured, orstored, use explosion-proof electrical equipment andfittings.

Shipping

This compound requires a shipping label of“FLAMMABLE LIQUID.” It falls in Hazard Class 3 andPacking Group II.

Incompatibilities
