Reduction reaction
A reduction reaction is an extremely important reaction in synthesizing various organic compounds. TAOKA has a substantial track record in industrialization, including the conversion of the nitro group into the amino group by a hydrogenation reaction, and a reaction to reduce the carbonyl group using borohydrides.
· Hydrogenation reaction
· Borohydride reduction
Halogenation reaction
TAOKA has a substantial track record in successfully achieving the industrialization of numerous processes that include halogenation reactions using thionyl chloride, sulfuryl chloride, bromine, etc. For bromine, in particular, we own a tank at the company.
