In Tierversuchen wurden keine Hinweise auf sensibilisierende oder mutagene Eigenschaften gefunden. Isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone. In that year, 5400 metric tonnes were used for household purposes and in personal care products. Isopropyl alcohol vapor is denser than air and is flammable, with a flammability range of between 2 and 12.7% in air. It is primarily produced by combining water and propene in a hydration reaction or by hydrogenating acetone. Microsoft Internet Explorer 6.0 unterstützt einige Funktionen auf Chemie.DE nicht. Concentrations of 60 to 90% work best.

It is a structural isomer of 1-propanol. [31] Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone. Search results for Isopropanol at Sigma-Aldrich. 3 Herstellung. Isopropanol ist mit Wasser in jedem Verhältnis homogen mischbar und bildet ein konstant siedendes (azeotropes) Gemisch bei 80,4 °C und 12,1 % Wasseranteil. Rubbing alcohol, hand sanitizer, and disinfecting pads typically contain a 60–70% solution of isopropyl alcohol or ethanol in water. This is an efficient process and easy, In 1990, 45,000 metric tonnes of isopropyl alcohol were used in the United States, mostly as a solvent for coatings or for industrial processes. Beim Umgang für ausreichende Lüftung sorgen. Water is required to open up membrane pores of bacteria, which acts as a gateway for isopropyl alcohol. [9] 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. [2] In rare cases, respiratory failure leading to death in animals was observed. This type of process usually requires higher-purity propylene (> 90%). 2-Propanol, auch als Isopropylalkohol oder Isopropanol (abgekürzt IPA) bekannt, ist der kleinste nicht-cyclische, sekundäre Alkohol. The wholesale cost in the developing world is about 1.80 to 9.50 USD per litre of 70% denatured ethanol. [16] Direct hydration is more commonly used in Europe. [31], Isopropyl alcohol is oxidized to form acetone by alcohol dehydrogenase in the liver,[31] and has a biological half-life in humans between 2.5 and 8.0 hours. Isopropyl alcohol and its metabolite, acetone, act as central nervous system (CNS) depressants. Es ist deshalb ratsam IPA vor dem Abdestillieren auf Peroxide zu prüfen. Wer Isopropanol nicht erst selbst verdünnen möchte, der erhält im Handel auch fertige Isopropanol-Lösungen mit einer Konzentration von 70%. [3][4][5] In zehn Jahre alten Originalgebinden von Isopropanol wurde beispielsweise ein Peroxidgehalt von 1% festgestellt. Zum Nass-Abspielen von Schallplatten: 50 % Isopropanol gemischt mit 50 % destilliertem Wasser. Isopropyl alcohol is esterified to give isopropyl acetate, another solvent. B. beim Spleissen von LWL-Fasern. Diisopropyl ether is a significant by-product of this process; it is recycled back to the process and hydrolyzed to give the desired product.[16].
