Aromatic Isocyanates from Biorenewables
Title: PROCESS FOR PREPARING POLYISOCYANATES FROM BIOMASS Number/Link: US2012302786 Applicant/Assignee: BASF Publication date: 29-11-2012 “Gist”: Lignin is reduced to hydroxy- or alkoxy monocyclic aromatics by pyrolysis (e.g.), condensed with formaldehyde, aminated and subsequently phosgenated to produce isocyanates. Why it is interesting: The use of renewable raw materials has been a steeply rising trend in the polyurethane science- and patent […]
