Epoxy thermosets from model mixtures of the lignin-to-vanillin process

Epoxy thermosets were prepared from mixtures of phenolics modelling the product stream of the ligninto-vanillin process. Vanillin is one of the only mono-aromatic compounds produced on an industrial scale from lignin. This process leads to mixtures of phenolic compounds. Isolation of pure vanillin is costly both economically and environmentally. The present work demonstrates that these purifica...

Biodegradable, elastic shape-memory polymers for potential biomedical applications.

The introduction of biodegradable implant materials as well as minimally invasive surgical procedures in medicine has substantially improved health care within the past few decades. This report describes a group of degradable thermoplastic polymers that are able to change their shape after an increase in temperature. Their shape-memory capability enables bulky implants to be placed in the body ...

Solvent-free direct ortho C-acylation of phenolic systems by methanesulfonic acid as catalyst

The use of methanesulfonic acid as a Brønsted acid for direct ortho-acylation of phenols and naphthols proves to be a convenient, more general and direct route to various hydroxyaryl ketones. The route is regioselective, leading to ortho C-acylated products in satisfactory to high yields in most cases. The solvent free reactions described below exhibited environmentally benign in terms of faste...
