Runninfarmer Posted October 5, 2009 Share Posted October 5, 2009 Hi, I was wondering if there was a cheap way to make 1-propanol from isopropyl alcohol, since IPA is so cheaply available? I'm making a catalyst and I need a primary alcohol and 1-propanol has the best properties for my procedure. Thanks a bunch for any help! Link to comment Share on other sites More sharing options...
dttom Posted October 6, 2009 Share Posted October 6, 2009 maybe... isopropyl alcohol --c.sulfuric acid--> propylene --HBr--peroxide--> 1-bromopropane--hydroxide--> 1-propanol Link to comment Share on other sites More sharing options...
Horza2002 Posted October 7, 2009 Share Posted October 7, 2009 Another way would be to treat isopropanol with conc sulphuric to get propene...and then perform a hydroboration reaction with a basic peroxide workup Link to comment Share on other sites More sharing options...
UC Posted October 7, 2009 Share Posted October 7, 2009 There is no easy way to do the conversion between the two. Since intermediates involving a carbocation are more stable for a secondary position than the primary position of n-propanol, interconversion is not favored. Reagents that generate a primary alcohol are quite expensive. You're better off seeking out some commercially available source. Link to comment Share on other sites More sharing options...
