I'm going to try out the transesterification of propylene carbonate and methanol. I know that the mechanism is as follows :

enter Transesterification

-What are the products yielded after the reaction?

-And which catalyst should I use? (reaction is happening at normal air pressure and at room temperature)

  • $\begingroup$ What you have listed is not a mechanism. Also, those structures are not propylene carbonate nor methanol. Maybe you should look at the actual structures and try to figure out yourself. $\endgroup$ – Nope Sep 11 '13 at 13:18

    $\begingroup$ * the mechanism is an example mechanism (See the wikipedia page about transeserification) $\endgroup$ – user2117 Sep 11 '13 at 17:26

I know it is used to obtain dimethyl carbonate (DMC) I think the others products should vary from which catalyst you choose. Have a look to Transesterification of propylene carbonate with methanol using $\ce{MgAlCO3}$ hydrotalcite as solid base catalyst: Indian Journal of Chemistry Vol. 49A, September 2010, pp. 1182-1188 to choose the catalyst. I think there are two little typos in Scheme 2 where the mechanism is shown: miss $\ce{^-}$ from $\ce{CH_3O^-}$ (first step) and miss $\ce{C}$ from one part ($\ce{CH_3CO}$) of DMC formula (second step) but is a good article.
