This is possible because DNA is insoluble in isopropyl alcohol. [16], Isopropyl alcohol dissolves a wide range of non-polar compounds. pp 2143–2184, "A new method for the determination of the relative acidities of alcohols in alcoholic solutions. Alcohols, in various forms, are used within medicine as antiseptics, disinfectants, and as an antidote. Together with ethanol, n-butanol, and methanol, it belongs to the group of alcohol solvents, about 6.4 million tonnes of which were used worldwide in 2011.[20]. 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. Concentrations of 60 to 90% work best.

Isopropyl alcohol is popular in particular for pharmaceutical applications,[16] due to its low toxicity. Types of alcohol used include ethanol, denatured ethanol, 1-propanol, and isopropyl alcohol. Peroxid-Konzentrationen bis 4,2% wurden berichtet. It is a structural isomer of 1-propanol. The wholesale cost in the developing world is about 1.80 to 9.50 USD per litre of 70% denatured ethanol.

This type of process usually requires higher-purity propylene (> 90%). Contents. Erfahren Sie mehr über das Unternehmen LUMITOS und unser Team.

[10] It has a slightly bitter taste, and is not safe to drink.[10][11].

A 75% v/v solution in water may be used as a hand sanitizer.

[26][29][30] Wearing protective gloves is recommended. Die Propylgruppe ist eine Atomanordnung der organischen Chemie mit der Summenformel C 3 H 7.Sie lässt sich gedanklich durch Abstraktion eines Wasserstoffatoms aus Propan ableiten und tritt in zwei isomeren Formen auf. Isopropyl alcohol is esterified to give isopropyl acetate, another solvent. Erfahren Sie, wie LUMITOS Sie beim Online-Marketing unterstützt. Molecular Formula: C 3 H 10 O 2: Synonyms: isopropanol-water. 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. [16] 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. The process is colloquially called salting out, and causes concentrated isopropyl alcohol to separate into a distinct layer. Isopropyl alcohol and its metabolite, acetone, act as central nervous system (CNS) depressants. Isopropyl alcohol (IUPAC name propan-2-ol), also called isopropanol or dimethyl carbinol, is a compound with the chemical formula C 3 H 8 O or C 3 H 7 OH or CH 3 CHOHCH 3 (sometimes represented as i-PrOH). It is primarily produced by combining water and propene in a hydration reaction or by hydrogenating acetone. These processes give primarily isopropyl alcohol rather than 1-propanol, because adding water or sulfuric acid to propene follows Markovnikov's rule. Isopropyl alcohol is often sold in aerosol cans as a windshield or door lock deicer. A known issue is the formation of MIBK and other self-condensation products.

Like most alcohols, isopropyl alcohol reacts with active metals such as potassium to form alkoxides that can be called isopropoxides. farblose Flüssigkeit mit alkoholartigem Geruch, Zusatz in Offsetdruckmaschinen mit Alkoholfeuchtwerken, um die Oberflächenspannung des Feuchtmittels herabzusetzen (sogenannter 'Wischwasserzusatz'), Herstellung von Desinfektionsmitteln (70 %iger IPA in Wasser besitzt beispielsweise eine höhere Wirkung als entsprechend verdünntes Ethanol), Lösungs- und Verdünnungsmittel in kosmetischen und pharmazeutischen Zubereitungen, Reinigungsmittel in Industrie und Haushalt/Fettlöser. Mit einem haben Sie immer alles im Überblick - und können sich Ihre eigene Website und Ihren individuellen Newsletter konfigurieren. [32] Die großtechnische Herstellung erfolgt auf zwei verschiedenen Wegen, ausgehend von Propen oder von Aceton. Mittlerweile kaufe ich aber Isopropanol fertig als 70%ige Lösung. Furthermore, there is no indication for the use of fomepizole, an alcohol dehydrogenase inhibitor, unless co-ingestion with methanol or ethylene glycol is suspected. Some isopropyl alcohol is used as a chemical intermediate. Es ist deshalb ratsam IPA vor dem Abdestillieren auf Peroxide zu prüfen. [19], Except where otherwise noted, data are given for materials in their, CRC Handbook of Chemistry and Physics, 44th ed. Früher habe ich Isopropanol auch in Reinform gekauft und dann gemäß der obigen Anleitung verdünnt. Isopropyl alcohol is also known as 2-propanol, sec-propyl alcohol, IPA, or isopropanol. 1 Structures Expand this section. Isopropyl alcohol is often used in DNA extraction. Subsequent hydrolysis of these esters by steam produces isopropyl alcohol, by distillation. © 1997-2020 LUMITOS AG, All rights reserved,

[1], Isopropyl alcohol is miscible in water, ethanol, ether, and chloroform. 2-Propanol (IUPAC Name); 2-hydroxypropane; 2-Propyl alcohol; Dimethyl Carbinol; IpA; i-Propyl alcohol; Isopropanol; iso-propanol; Iso-propyl alcohol; isopropylalcohol; propan-2-ol; Secondary Propyl Alcohol; sec-propanol. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. [31] Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone. [21] 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. Isopropanol kann bereits als 70%ige Lösung gekauft werden. [33], In forensic pathology, people who have died as a result of diabetic ketoacidosis usually have blood concentrations of isopropyl alcohol of tens of mg/dL, while those by fatal isopropyl alcohol ingestion usually have blood concentrations of hundreds of mg/dL.

Water is required to open up membrane pores of bacteria, which acts as a gateway for isopropyl alcohol. Alcohol does not remove water from gasoline, but the alcohol solubilizes water in gasoline. The reaction with aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide. Create: 2007-12-05.
