Abstract
This invention relates to performance chemicals field, it discloses a novel and green process for simultaneous productions of formamides as well as mono- and multi-functional acrylamides under very mild conditions and with high efficiency. These substances are widely useful as industrial solvents or raw materials, in particular acrylamides are important olefinically-unsaturated polymerizable monomers in photo-curing materials.
