Sequence from Ordering to Product Completion

Three organizations work closely together to implement your requests

The three organizations of the head office/Kansai branch office, development research organization, and production factories (Tatebayashi and Gunma) work together closely utilizing their respective skills to implement the orders received from customers. This is a system that has developed from long years of success.


We specialize in outsourced hydrogenation reactions utilizing our experience as a hydrogenation catalyst manufacturer. We have a diverse range of reaction outsourcing experience using a variety of autoclaves from the laboratory scale to pilot and full-scale production. In particular, we have large-scale autoclaves available which contribute to reducing the costs of outsourced products.

Data of Experience
Various hydrogenation reactionsHydrogenation, selective hydrogenation, reductive amination, dehalogenation, dealkylation, etc.
Hydrogenation purificationDecoloration, deodorization, hydrogenolysis, etc.

Specialist Technology

The Tatebayashi factory where we perform outsourced hydrogenation reaction manufacturing primarily specializes in the following technologies. In addition to the following technologies, we also handle requests for various reactions in related to fine chemicals from the laboratory stage to the full-scale production stage.

  • High pressure reactions (up to 15 MPa)

  • High temperature reactions (up to 230℃)

  • High viscosity (up to 500,000 cps [30℃])

  • Metal control (ppb)
