Specialty Intermediate

Our intermediates have applications in pigment, dye pharmaceutical and agrochemical industries

The Intermediate Business
  • Violetech Intermediate Division

    Utilizing advanced organic synthesis technologies, we produce various types of fine chemical intermediates, including 4-Chlorobenzonitirle, Chloranil, and Bromoethane. At the current stage, our intermediate business serves primarily in auxiliary to our main pigment business. With scalable and cost-effective production of key intermediates being secured, we are able to deliver high quality pigment products consistently whilst maintaining a competitive edge in terms of pricing and product deliverability.

  • Facilities and Capabilities

    1. Utilities Include: Nitrogen & Hydrogen Plant, Industrial Boiler, Thermic Fluid Boiler, Brine Chilling Plant, RTO System, Cooling Towers, Solid Waste Incinerator, Water Treatment Plant.
    2. Plant infrastructure include: Stainless Steel autoclaves/hydrogenator (75/150 bar pressure) –25 L/100 L, Stainless steel reactor with distillation column and condenser – 100 L, Thermic fluid boiler, Rotary vacuum dryer, Centrifuge.
    3. Process capabilities include: Alkylation, Nitration, Catalytic Hydrogenation, Condensation, Cyclisation, Sulfonation.

  • Toll Manufacturing & Business Collaboration

    With our production facilities and process capabilities, we stand ready to add values for customers in need of multi-step synthesis. We are actively evaluating potential opportunities in the field of intermediate synthesis, either to collaborate with companies that are looking for a manufacturing partner for new products, or to work as a toll-manufacturer for existing products.
