Highly pure alkyl 2-cyanoacrylates |
| abstract |
A process for the preparation of a highly pure alkyl 2-cyanoacrylate, wherein alkyl has 1-10 C atoms, characterized in that a) formaldehyde is reacted with an alkyl cyanoacetate ester by means of a catalyst in a solvent mixture selected from the group comprising ethylacetate, diglyme, dichloroethane and benzene, yielding an oligo-(alkyl 2-cyanoacrylate); b) the product of (a) is separated in the form of a solid; c) the product of (b) is depolymerized under sulfur dioxide atmosphere free from other polymerization inhibitors to yield an alkyl 2-cyanoacrylate with a purity of 98-100% |
