HPMC: A Biomass-Based Semisynthetic Sustainable Additive Enabling Clean and Fast Chemistry in Water

The two types of water chemistries are (i) on water and (ii) in water. The fundamental understanding of "on water" chemistry is very well-known. In contrast, "in water" chemistry is yet not well understood. Micellar catalysis is a major enabler of "in water" chemistry, while HPMC (hydroxypropyl methylcellulose)-based chemistry is new and therefore underdeveloped. This perspective is dedicated to the in water chemistry of HPMC....
