Methods of isopropyl alcohol

In 1855, The French M. Betelot first reported the use of propylene and sulfuric acid through water synthesis of isopropyl alcohol, called indirect water method. In 1919, an American, C. Ellis, developed it industrially. At the end of 1920, the New Jersey Standard Oil Company used Ellis method to establish a production device, formally put into production. In 1951, the British Chemical Industry company began to use propylene direct water production of isopropyl alcohol. Since then, countries have adopted this method and made improvements. Indirect water method: propylene reacts with sulfuric acid to form isopropyl hydrogen sulfate, which is hydrolyzed into isopropyl alcohol. The reaction formula is :CH3CH = CH2+H2SO4 →(CH3)2CHOSO3H; (CH3)2CHOSO3H+H2O─→(CH3)2CChemicalbookHOH+H2SO4, the sulfuric acid concentration is generally greater than 60% (mass), the reaction at 2 ~ 2.8MPa and 60 ~ 65°C; Hydrolysis takes place at slightly higher pressure and below 30°C. Direct water method: propylene and water in the presence of catalyst heating, pressure hydration reaction, isopropyl alcohol, selectivity is 96%. The reaction formula is: CH3CH = CH2+H2O →(CH3)2CHOH the catalyst used are tungsten compounds, phosphoric acid and ion exchange resin, etc., the more commonly used is phosphoric acid catalyst with carrier (see solid acid catalyst), the process conditions are 2 ~ 6MPa, 240 ~ 260°C. Compared with indirect method, this method has no problems such as sulfuric acid corrosion and dilute acid concentration, so it plays a major role in industrial production.


APPLICATION of isopropyl alcohol

Isopropyl alcohol is an important chemical product and raw material, mainly used in pharmaceutical, cosmetics, plastics, spices, coatings and electronic industry as a dehydrating agent and cleaning agent.
