US 10260023 B2, CN106536494B, IN 2225/DEL/2014, WO 2016020941A3, BR 112017001289A2

Application/Uses/Problem being addressed

Lubricants, fuel additives, in automobile industries, in polymers, etc.

Salient Technical Features including Competing Features/ Impact

  • Use of castor oil and its derivatives as raw material which are very cheap non-edible oil.
  • Low-cost and commercially available catalysts are used as solid catalysts for the preparation of functionalized castor oil derivatives such as ring-opened glyceryl ricinoleates, epoxy alkyl ricinoleates and ring-opened alkyl ricinoleates.
  • High yields of the products under benign reaction conditions
  • Reaction chemistry can be altered by choosing different catalysts
  • Catalysts are recyclable
  • Physical properties of the functionalized castor oil derivatives suggest the possibility of tailoring the values by suitably choosing the appropriate nucleophiles/reaction chemistry or by simple blending of them.

    • TRL Level & Scale of Development:- TRL 5 TRL Reference

    • Methoxylated castor polyol (MCP) and isopropoxylated castor polyol (IPCP) - Scaled up at 100 g
    • Epoxy methyl ricinoleate (EMR) - Scaled up at 50 g
    • Methoxylated methyl ricinoleate (MMR) - Scaled up at 250 g
    • Remaining all reactions - scaled up at 25 g

    Business scope & opportunity (in terms of scale, cost, market etc.)

    As India being a largest producer of castor oil, abundant scope is there to diversify different oleochemicals industry for several applications, such as lubricants, plasticizers, additives, etc.

    Environmental Considerations

    Utilization of non-edible source castor oil) for the preparation of value-added chemicals to overcome food vs fuel issues created by edible oils.

    Catalysts are easily recoverable (simple filtration) without any further addition of chemicals and reusable.
