摘要: A process to produce propanol and iso-propanol (bio-propanol), a biocomponent for gasoline relates to the conversion of bio-glycerin to bio-propanol and bio-iso-propanol.
In particular, a process is related for the conversion of glycerin, in particular glycerin from renewable sources, to propanols, the process including the following steps:
(a) hydrogenating a glycerin phase with a Co—Cu—Mn—Mo based hydrogenation catalyst to give an effluent containing water and an organic mixture of more than 40 wt % of a mixture of ethanol, 1-propanol and 2-propanol and the rest being unreacted propanediols and glycerin, with traces of ethylene glycol;
(b) separating by mainly distillation the ethanol, 1-propanol and 2-propanol mixture from the other components in the effluent of step a); and (c)
optionally, recycling all or part of the unreacted propandiols and glycerin deriving from steps a) and/or b) to the hydrogenation step a).-

摘要: The present invention relates to a process for preparing an ester having formula R—COO—R′ (I), wherein R represents a group selected from: (i) a linear or branched alkyl, containing from 1 to 20 carbon atoms, (ii) an aryl containing from 6 to 12 carbon atoms, (iii) a heterocycle with 4 to 12 carbon atoms containing at least one heteroatom selected from O, N, P and S, R′ represents a linear or branched alkyl containing from 1 to 12 carbon atoms, said process comprising at least a phase of reacting a reaction mixture comprising at least one aldehyde having formula R—CHO (II), wherein R has the meanings defined above, and at least one alcohol having general formula R′—OH (III), wherein R′ has the meanings defined above, in the presence of at least one solid basic catalyst, at a temperature within the range of 120° C.-300° C., obtaining said ester having formula (I).
