Preparations of Primary Phosphines

UVM Reference Number: C790
Summary:

A clean phosphine synthesis method that circumvents the use of toxic reagents, uses industrially common hydrogen and produces no waste

Background:

Primary phosphines are highly versatile precursors and are used as commercial reagents in industries such as pharmaceutical manufacturers, agriculture (pesticides), and materials science industries (semiconductors). Current production processes use highly hazardous reagents, creating substantial amounts of hazardous waste and low yield (i.e., inefficient). Primary phosphines are currently imported due to these challenges and the types available are limited to three.

Technology Overview:

Researchers at UVM have identified a clean phosphine synthesis method that circumvents the use of toxic reagents, uses industrially common hydrogen and produces no waste. With this new method, expansion of the number of different phosphines is possible, as well as domestic production, expanding the portfolio of phosphines available for new and safer products.

Benefits:

  • Safe and efficient preparation of primary phosphines feedstock
  • Avoids use of hazardous reagents
  • Allows production of thousands of possible phosphines vs three available now
  • Domestic production possible with reduced production hazards

Applications:

  • Feedstock for pharma, agriculture and the semiconductor industry
