Diisopropyl ether Chemical Properties,Usage,Production

Description

Diisopropyl ether [108-20-3], also known as 2-isopropoxyisopropane or isopropyl ether, is a clear, colorless, mobile, highly flammable liquid with a characteristic ethereal odor. Its solubility in water is low, but it is soluble in organic solvents and readily forms explosive peroxides. It has a higher boiling point, a lower vapor pressure, and a lower water solubility than diethyl ether, which means that diisopropyl ether can be recovered without significant loss after use as a solvent or as an extractant.

Chemical Properties

Diisopropyl ether(Isopropyl ether) is highly flammable, with a wide flammable range of 1.4%–21% in air. Boiling point is 156°F (68°C), flash point is 18°F (27°C), and ignition temperature is 830°F (443°C). Vapor density is 3.5, which is heavier than air. In addition to flammability, isopropyl ether is toxic by inhalation and a strong irritant, with a TLV of 250 ppm in air. Diisopropyl ether is an excellent solvent for natural oils, mineral oils, and waxes. It is used as an extracting agent and reaction medium in chemical and pharmaceutical syntheses.

Physical properties

Clear, colorless, volatile, flammable liquid with a penetrating, sweet, ether-like odor. Experimentally determined detection and recognition odor threshold concentrations were 70 μg/m3 (17 ppbv) and 220 μg/m3 (53 ppbv), respectively (Hellman and Small, 1974).

Uses

Isopropyl ether is used as a solvent for oils,waxes, resins, and dyes; and as a varnishremover.

Preparation

Diisopropyl ether can be prepared by liquid-phase dehydration of 2-propanol at 130 – 190°C and 1.96– 7.85 MPa over acidic catalysts containing aluminum.

General Description

Diisopropyl ether appears as a clear colorless liquid with an ethereal odor. Flash point -18°F. Less dense than water. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Slightly soluble in water. Form explosive peroxide in storage. A flask of Isopropyl ether was heated on a steam bath with gentle shaking when an explosion occurred. In a second instance, an explosion occurred after practically all the ether had been distilled, [MCA Guide for Safety(1972)].

Reactivity Profile

Ethers, such as Isopropyl ether, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert. Mixing Isopropyl ether in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, [NFPA 1991].

Hazard

Flammable, dangerous fire risk, explosive limits in air 1.4–21%. Toxic by inhalation, strong irritant.

Health Hazard

Isopropyl ether is a narcotic and an irritant tothe skin and mucous membranes. It is moretoxic than ethyl ether and the toxic symptomsare similar to the latter compound. Inhalationof its vapors can produce anesthetic effects.Exposure to high concentrations can causeintoxication, respiratory arrest, and death.Exposure to 3.14% and 2.9% of isopropylether in air (by volume) produced the symp toms of somnolence, change in motor activ ity, and muscle contractions in mice andrabbits, respectively, causing the death of50% of test animals. Exposure to 7–10% byvolume concentration in air can be fatal tohumans
Acute oral toxicity of isopropyl ether islow. The liquid is irritating to the mucousmembranes. Skin contact may cause mildirritation, and repeated exposure may causedermatitis. The irritation effect of isopropylether on eyes is mild. In humans, exposureto 800 ppm in air for a few minutes causedirritation of the eyes and nose. There is noreport of its carcinogenic action in animalsor humans.

Fire Hazard

Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. Containers may explode when heated.

Flammability and Explosibility

Highly flammable

Industrial uses

Isopropyl ether is a solvent of minor importance since its boiling point is intermediate between the two widely used solvents diethyl ether and acetone. Hazardous peroxides are formed more readily in isopropyl ether than in other dialkyl ethers.

Potential Exposure

ReproductiveEffector; Human Data; Primary Irritant. This material isused as a solvent, additive for gasoline, and a chemicalintermediate.

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 theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

Source

Some unleaded gasoline may contain isopropyl ether and other oxygenates as an octane booster and to prevent engine knock.

Environmental Fate

Biological. Bridié et al. (1979) reported BOD and COD values of 0.19 and 1.75 g/g using filtered effluent from a biological sanitary waste treatment plant. These values were determined using a standard dilution method at 20 °C and stirred for a period of 5 d. The ThOD for isopropyl ether is 2.82 g/g.
Chemical/Physical. May form explosive peroxides on standing with air (NIOSH, 1997). At an influent concentration of 1,018 mg/L, treatment with GAC resulted in an effluent concentration of 203 mg/L. The adsorbability of the GAC used was 162 mg/g carbon (Guisti et al., 1974).
Isopropyl will not hydrolyze in water except at elevated temperatures and low pH.

storage

Isopropyl ether is stored in a flammable-liquids storage room, isolated from combustible and oxidizing materials. It shouldalso be protected from direct sunlight, staticelectricity, and lightning. It is stabilized with0.01% hydroquinone or p-benzylaminphenol.The ether is shipped in amber glass bottles,steel cans, and drums.

Shipping

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

Purification Methods

Common impurities are water and peroxides [detected by the liberation of iodine from weakly acid (HCl) solutions of 2% KI]. Peroxides can be removed by shaking with aqueous Na2SO3 or with acidified ferrous sulfate (0.6g FeSO4 and 6mL conc H2SO4 in 110mL of water, using 5-10g of solution per L of ether), or aqueous NaBH4 solution. The ether is then washed with water, dried with CaCl2 and distilled. Alternatively, refluxing with LiAlH4 or CaH2, or drying with CaSO4, then passage through an activated alumina column, can be used to remove water and peroxides. Other dehydrating agents used with isopropyl ether include P2O5, sodium amalgam and sodium wire. (The ether is often stored in brown bottles, or in the dark, with sodium wire.) Bonner and Goishi (J Am Chem Soc 83 85 1961) treated isopropyl ether with dilute sodium dichromate/sulfuric acid solution, followed by repeated shaking with a 1:1 mixture of 6M NaOH and saturated KMnO4. The ether is washed several times with water, dilute aqueous HCl, and water, with a final washing with, and storage over, ferrous ammonium sulfate acidified with H2SO4. Blaustein and Gryder (J Am Chem Soc 79 540 1957), after washing with alkaline KMnO4, then water, treated the ether with ceric nitrate in nitric acid, and again washed it with water. Hydroquinone is added before drying with CaCl2 and MgSO4, and refluxing with sodium amalgam (108g Hg/100g Na) for 2hours under nitrogen. The distillate (nitrogen atmosphere) is made 2 x 10-5M in hydroquinone to inhibit formation of peroxides (which is negligible if the ether is stored in the dark). Catechol (pyrocatechol) and resorcinol are alternative inhibitors. [Beilstein 1 IV 1471.]

Incompatibilities

Forms explosive mixture with air. Aircontact forms explosive peroxides that may explode withheat or shock. Contact with strong oxidizers or strong acidsmay cause a fire and explosion hazard. Attacks some plastics, rubber, and coatings.

Waste Disposal

Isopropyl ether is burned in a chemicalincinerator equipped with an afterburner andscrubber. A small amount of ether, if free ofperoxides, can be evaporated in a fume hoodin the absence of any open flame or sourceof ignition nearby.
