C3hydrolyse

C3Hydrolyse is a catalytic hydrolysis technology that converts C3 organic molecules—such as glycerol, 1,4-butanediol, and propan-1-ol—into valuable products through hydration reactions. The process uses a combination of acid or base catalysts and hydrogen gas or water under controlled temperature and pressure conditions, enabling efficient cleavage of carbon–oxygen bonds. It is designed to operate with high selectivity, minimizing side reactions and producing high-purity outputs suitable for industrial use.

The concept dates back to the early 2000s, when researchers sought to unlock the potential of low‑value glycerol, a byproduct of biodiesel production. Initial studies focused on acid‑catalyzed pathways that yielded organophosphoryl compounds, but the introduction of metal‑based catalysts such as nickel, cobalt, and ruthenium improved conversion rates and reduced reaction times. Subsequent work explored heterogeneous catalysis on supported oxide materials, allowing for catalyst regeneration and more sustainable operation.

Mechanistically, C3Hydrolyse involves the addition of water across a C3 alkene or alkyne under catalytic influence. In acid‑catalyzed routes, protonation of the molecule activates the carbon chain for nucleophilic attack by water, leading to alcohol or aldehyde intermediates that can further be processed into diols or acetals. In metal‑catalyzed hydrogenation, the C3 substrate adsorbs onto the catalyst surface, where hydrogen atoms facilitate the breaking of C–O bonds and formation of saturated hydrocarbon chains or oxygenated additives.

The technology has found use in producing biobased solvents, softeners, and as a feedstock for the synthesis of polymer monomers such as propylene glycol. It also enhances waste valorisation in the chemical sector, turning biomass derivatives into high‑value commodities while reducing reliance on petrochemicals. Current research aims to integrate C3Hydrolyse with renewable hydrogen sources, improve catalyst durability, and scale the process for commercial production of green plastics and fuels.
