Fluoro Organics

History

The Fluoroorganic Division is established way back in 1992 to pursue R&D on development of technologies for hydrofluorocarbons which are considered as well recommended substitutes for ozone depleting chlorofluorocarbons (CFCs) and Halons. Identifying a dedicated team and establishing a separate division is a unique idea and vision of IICT and such an expertise is not available among the other CSIR labs or academic institutions of India. Further, it is also aimed to develop innovative and indigenous processes for fluorinated Pharma & Agro intermediates. Thus, Fluoroorganic Division primarily initiated work on a most complex technology for 1,1,1,2-Tetrafluoroethane (HFC-134a) by catalytic vapour phase fluorination reaction using anhydrous hydrogen fluoride as fluorinating agent at elevated temperatures and pressures. The heart of the process is catalyst. A new catalyst was developed without infringing intellectual property of other patents and the innovation made in technology is protected in the form of new patents. The developed technology for HFC-134a from lab scale to semi- commercial scale was transferred to two Indian industries which were subsequently commercialized the HFC-134a process and product is available to end users.

Similarly, Fluoroorganic Division developed a process for 2H-Heptafluoropropane (HFC-227ea) on lab scale to pilot scale and demonstrated to CFEES, New Delhi and is under commercial implementation by M/s. GFL, Gujarat. In addition to the above major products, the Division also developed process for 3-chloro-4-fluoroaniline, 2,4-dichlorofluorobenzene, 1,1,1-trichlorotrifluoroethane, 2,2,2-trifluoroethanol, trifluoroacetic acid, l,l-difluoro-2-chloroethane and fluoromonomers such as chlorotrifluoroethylene (CTFE) and vinylidene fluoride (VDF). Further, Fluoroorganic Division has also successfully completed several contract and sponsored projects on important fluorochemicals from internationally reputed companies. The Division has developed expertise on Electrochemical fluorination of carbon nano tubes, layered materials such as graphite, molybdenum disulfide using fluorinating adducts: pyridinium poly(hydrogen fluoride), triethylamine 3HF at room temperature. The Division is also actively involved in organic synthesis by designing and synthesising new potential bioactive molecules and their evaluation as antibacterial, anticancer and antimalarial etc.

The Division has achieved several Institutional Best Performance awards (i) for successful mechanical commissioning of 5 kg/hour pilot plant on HFC-134a (multidisciplinary project) during 2001-02; (ii) for successful transfer of technology for Heptafluoropropane (HFC-227ea) (2006); (iii) for Process know-how for the synthesis of Acetohydroxamic Acid (2008); (iv) for Process know-how for Siloxane Fluoroalcohol (2009); (v) for Process know-how for the Synthesis of Formohydroxamic Acid (2010) and (vi) for developing process for Fluoroelastomer for plastic bonded explosive applications (2012).
