Furthermore, there is no indication for the use of fomepizole, an alcohol dehydrogenase inhibitor, unless co-ingestion with methanol or ethylene glycol is suspected.

��9x#�� 0 �`4� Isopropyl alcohol (IUPAC name propan-2-ol; commonly called isopropanol or 2-propanol) is a colorless, flammable chemical compound (chemical formula CH 3 CHOHCH 3) with a strong odor. Dissolve 10 mg or 2 drops of the unknown in 1 mL of pure acetone in a test tube and add to the solution 1 small drop of Jones reagent (chronic acid in sulfuric acid).

Only buy isopropanol in recognized containers with official labels and from proper vendors. [31] Poisoning can occur from ingestion, inhalation, or skin absorption. [10] It has a slightly bitter taste, and is not safe to drink.[10][11]. Once soluble, water does not pose the same risk as insoluble water, as it no longer accumulates in the supply lines and freezes but is consumed with the fuel itself. Raney nickel was one of the original industrial catalysts, modern catalysts are often supported bimetallic materials. [10], Isopropyl alcohol forms an azeotrope with water, which gives a boiling point of 80.37 °C (176.67 °F) and a composition of 87.7 wt% (91 vol%) isopropyl alcohol. %PDF-1.6 %���� Alcohol does not remove water from gasoline, but the alcohol solubilizes water in gasoline. ?n:��8Hs�+��n@�^�5��p\\��GJvc'i�&7�(R�(�1i#����5��F��Pځ����3�z��3��2 ��^�8�y��AGV�p[ RրT�çOɨ\�U��Ms� -���`�|y���:��p����a\�j�M&�Q\�$YPTQP�ECaD�Q��mUNӼ�Kn?��I�\�w����2[�30��=.��-��-�9 h�bbd``b`Z$�� ��$��$�XW@�"WD��!$��1012��e`���ϸ�@� �� Isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone. Isopropyl alcohol and water form an azeotrope, and simple distillation gives a material that is 87.9% by weight isopropyl alcohol and 12.1% by weight water.
Commercial producers of alcohol have specialized methods of removing methanol from their products, but home and hobby brewers tend not to have t… However, it was soon discontinued, as many complications arose, including respiratory irritation, internal bleeding, and visual and hearing problems. [8] As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. pp 2143–2184, "A new method for the determination of the relative acidities of alcohols in alcoholic solutions. [19], Except where otherwise noted, data are given for materials in their, CRC Handbook of Chemistry and Physics, 44th ed. Dissolve 0.5 g in 1.5 ml ofwater R and add 3.5 ml of 2-propanol R. Scratch the wall of the tube with a glass rod to initiate crystallisation. [1], Isopropyl alcohol is miscible in water, ethanol, ether, and chloroform. Isopropyl alcohol is often sold in aerosol cans as a windshield or door lock deicer. Isopropyl alcohol is often used in DNA extraction. Methanol provides the same buzz as ethanol, and occurs naturally at low levels in fermented drinks but is far more toxic than ethanol, to the point that it can cause severe illness and death.

This type of process usually requires higher-purity propylene (> 90%). Isopropyl alcohol can also be used similarly to ether as a solvent[24] or as an anesthetic by inhaling the fumes or orally.

[16] Direct hydration is more commonly used in Europe. 77 0 obj <>stream Isopropyl alcohol and its metabolite, acetone, act as central nervous system (CNS) depressants.

Isopropyl alcohol is popular in particular for pharmaceutical applications,[16] due to its low toxicity.
