23 Facts About Isopropyl alcohol
1.
2.
Isopropyl alcohol is miscible in water, ethanol, and chloroform as, like these compounds, isopropyl is a polar molecule.

3.
Unlike ethanol or methanol, isopropyl alcohol is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride.

4.
Isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone.
| FactSnippet No. 1,598,911 |
5.
Isopropyl alcohol is often used as both solvent and hydride source in the Meerwein-Ponndorf-Verley reduction and other transfer hydrogenation reactions.
| FactSnippet No. 1,598,912 |
6.
Isopropyl alcohol was oxidized to acetone for the preparation of cordite, a smokeless, low explosive propellant.
| FactSnippet No. 1,598,913 |
7.
Pure isopropyl alcohol is made by azeotropic distillation of the wet isopropyl alcohol using either diisopropyl ether or cyclohexane as azeotroping agents.
| FactSnippet No. 1,598,914 |
8.
Isopropyl alcohol can be prepared via the hydrogenation of acetone; however, this approach involves an extra step compared to the above methods, as acetone is itself normally prepared from propene via the cumene process.

10.
Isopropyl alcohol is popular in particular for pharmaceutical applications, due to its low toxicity.
| FactSnippet No. 1,598,917 |
11.
Isopropyl alcohol is commonly used for cleaning eyeglasses, electrical contacts, audio or video tape heads, DVD and other optical disc lenses, removing thermal paste from heatsinks on CPUs and other IC packages.

13.
Isopropyl alcohol reacts with titanium tetrachloride and aluminium metal to give titanium and aluminium isopropoxides, respectively, the former a catalyst, and the latter a chemical reagent.

14.
Isopropyl alcohol is used as a water-drying aid for the prevention of otitis externa, better known as swimmer's ear.
| FactSnippet No. 1,598,921 |
15.
Isopropyl alcohol can be used similarly to ether as a solvent or as an anesthetic by inhaling the fumes or orally.

18.
Isopropyl alcohol is used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid does not contaminate the brake pads and cause poor braking.
| FactSnippet No. 1,598,925 |
19.
Isopropyl alcohol vapor is denser than air and is flammable, with a flammability range of between 2 and 12.

20.
Isopropyl alcohol causes eye irritation and is a potential allergen.
| FactSnippet No. 1,598,927 |
21.
Symptoms of isopropyl alcohol poisoning include flushing, headache, dizziness, CNS depression, nausea, vomiting, anesthesia, hypothermia, low blood pressure, shock, respiratory depression, and coma.
