Ammonium chloroiridate (black salt)

Ammonium hexachloroiridate(IV) | CAS: 16940-92-4

C4-005

CAS Number: 364732-88-7

PGM refining

As the largest secondary Platinum Group Metals (PGM) refiner in the world, we've developed highly advanced processes for extracting and separating PGMs from products – so advanced that we can refine to a purity of 99.95%.

RTA-25

Aromatic and aliphatic primary amines can be obtained using our Transaminases

Vinyl chloride monomer (VCM) process

Johnson Matthey offers a well-established VCM technology which is recognised by industry as the most advanced acetylene-to-VCM process worldwide.

Oxo alcohols process

Johnson Matthey offers oxo-alcohol processes and a complete range of catalysts suitable for oxo-alcohol manufacture. The LP OxoSM technology is the world’s leading technology for use in the manufacture of oxo alcohols from olefins.

C4-008

CAS Number: 364732-86-5

Product stewardship

Gold chloride solution (40% w/w Au)

Hydrogen tetrachloroaurate(III) solution | CAS: 16903-35-8

Chloroiridic acid crystal (CIA) Ir-114

Hydrogen hexachloroiridate(IV) solid | CAS: 16941-92-7

Synthesis technology

Johnson Matthey's DAVY™ synthesis technologies convert syngas (CO, CO2 & H2) to methanol creating exothermic reactions that have a limited conversion rate, so several passes through a reactor are required to produce sufficient methanol.

PL-134 (QPhos)

CAS Number: 312959-24-3

Environmental oxidation process

Environmental concerns about industrial emissions to air and water have been continually growing. In response, Johnson Matthey has targeted key issues by applying our expertise in catalysts and catalytic technology.
