Except where otherwise noted, data are given for materials in their (at 25 °C [77 °F], 100 kPa). Y ( Y N?) Isopropyl alcohol ( name propan-2-ol; commonly called isopropanol) is a with the C 3H 8O. It is a, chemical compound with a strong. As an group linked to a group, it is the simplest example of a, where the carbon atom is attached to two other carbon atoms. It is manufactured for a wide variety of industrial and household uses, and is a common ingredient in chemicals such as, disinfectants and detergents. Contents • • • • • • • • • • • • • • • • • • Properties [ ] Isopropyl alcohol, synonymous with 2-propanol, sec-propyl alcohol, IPA, isopropanol, or rubbing alcohol is in water,,, and.
It will dissolve,, many oils, alkaloids, gums and natural resins. Unlike or, isopropyl alcohol is not miscible with salt solutions and can be separated from by adding a salt such as. The process is colloquially called, and causes concentrated isopropyl alcohol to separate into a distinct layer. Isopropyl alcohol forms an with water, which gives a boiling point of 80.37 °C (176. The Surgeon Tess Gerritsen Ebook. 67 °F) and a composition of 87.7 wt% (91 vol%) isopropyl alcohol. Water-isopropyl alcohol mixtures have depressed melting points. It has a slightly bitter taste, and is not safe to drink. Isopropyl alcohol becomes increasingly viscous with decreasing temperature and will freeze at −89 °C (−128 °F).
Isopropyl alcohol has a maximum at 205 nm in an spectrum. Reactions [ ] Isopropyl alcohol can be to, which is the corresponding. This can be achieved using oxidizing agents such as, or by of isopropyl alcohol over a heated copper: (CH 3) 2CHOH → (CH 3) 2CO + Isopropyl alcohol is often used as both solvent and source in the and other reactions. Isopropyl alcohol may be converted to using, or dehydrated to by heating with. Like most alcohols, isopropyl alcohol reacts with active such as to form that can be called isopropoxides. The reaction with (initiated by a trace of ) is used to prepare the catalyst.
Production [ ] In 1994, 1.5 million tonnes of isopropyl alcohol were produced in the United States, Europe, and Japan. It is primarily produced by combining water and in a or by hydrogenating. There are two routes for the hydration process and both processes require that the isopropyl alcohol be separated from water and other by-products. Isopropyl alcohol and water form an and simple distillation gives a material that is 87.9% by weight isopropyl alcohol and 12. Jira Vmware Appliance Default. 1% by weight water. Pure () isopropyl alcohol is made by of the wet isopropyl alcohol using either or as azeotroping agents. Indirect hydration [ ] Indirect hydration reacts propene with to form a mixture of sulfate esters. This process can use low-quality propene, and is predominant in the USA.
