Hydroxypropionic acid catalytic dehydration: Procter & GambleRecent Research Landscape

The technical lever is the heterogeneous catalytic pathway used to control the selective elimination of water from hydroxypropionic acid. This enables the bio-based production of acrylic acid monomers with high atom economy.

What technical problems is Procter & Gamble addressing in Hydroxypropionic acid catalytic dehydration?

Low acrylic acid yield

(3)evidences

The dehydration of hydroxypropionic acid in the liquid phase often suffers from poor conversion rates and byproduct formation. Improving the yield is critical for the economic viability of bio-based acrylic acid production.

Organic contaminant interference

(2)evidences

The dehydration of hydroxypropionic acid often suffers from competing side reactions and byproduct formation. Improving selectivity increases product yield and reduces downstream purification costs.
