Feedstock for Indoline and Value Chain Dynamics

The industrial manufacturing process of Indoline via intramolecular Diels-Alder synthesis uses 3-alkynylalkylamino-1,2-diazine and 1,3,5-triisopropyl benzene (TIPB) as its core raw materials.

• 3-Alkynylalkylamino-1,2-diazine Sourcing: This is a complex speciality chemical. It is a primary feedstock and would be synthesised through a multi-step process from simpler petrochemicals like hydrazine and alkynes.
  • Upstream Chemical Prices: The cost of these precursors is tied to global petrochemical markets. The fluctuation in the prices of these raw materials directly impacts the cash cost of production for Indoline, which in turn, significantly influences the overall Indoline manufacturing plant cost.
• 1,3,5-Triisopropyl Benzene (TIPB) Sourcing: TIPB is a bulky aromatic compound prepared from benzene and propylene.
  • Petrochemical Prices: The cost of TIPB is linked to the prices of benzene and propylene. Changes in these upstream raw materials directly influence the production cost analysis for Indoline.
• Energy for Reaction: The Diels-Alder reaction described requires high temperatures.
  • Energy-Intensive Steps: The energy required for heating the reactors to 200–230 degree Celsius is a major part of operating expenses (OPEX). The distillation for purification also consumes significant energy.
• Solvents and Byproducts: The reaction uses TIPB as a solvent. The process may generate side reactions and byproducts.
  • Solvent Recovery: TIPB can be recovered and reused. The efficiency of this recovery is key to cost structure optimisation and a major factor in the overall cost model.
  • Waste Management: Managing waste streams from the synthesis process adds to manufacturing expenses.
