Reaction & Manufacturing Capabilities

Catalytic Hydrogenation & Hydrogenolysis

Catalytic hydrogenation is a core transformation in pharmaceutical, fine chemical and specialty chemical manufacturing. XinChem supports process development, scale-up and manufacturing for selected hydrogenation and hydrogenolysis projects.

Projects are evaluated according to substrate structure, catalyst system, reaction selectivity, pressure requirements, heat management, product isolation and target production scale.
