Continuous processes and apparatus for forming cyanoacetate and cyanoacrylate
摘要:
Continuous processes for forming cyanoacrylate from polycyanoacrylate include stripping a solvent from a reaction mass; cracking a polymer in the reaction mass to form a cracked cyanoacrylate monomer and residue substances; and distilling the cracked cyanoacrylate monomer to produce a cyanoacrylate monomer product. These steps can be performed in short-path, wiped-film evaporators. Polycyanoacrylate used in the processes can be formed using cyanoacetate produced by processes for continuously producing cyanoacetate by forming a higher homologue cyanoacetate from a lower homologue cyanoacetate. The cyanoacetate can be formed in short-path, wiped-film evaporators.
