Process for converting an aldehyde into an alkene, in particular furfural into furfurylidenes |
| abstract |
The invention relates to a process for converting an aldehyde into a corresponding alkene and of the type wherein the aldehyde is placed in the presence of a phosphoric reagent and a base in solution in an organic aprotic solvent; the process comprising using a mineral base evincing in an aqueous medium a basic force less than or equal to that of the hydroxide ion or a strongly basic organic base of the nitrogen compounds family and adjusting the hydration rate of the reaction medium in such a manner that there are about 0.5 to 5 moles of water per mole of aldehyde. |
