COMPANY PRODUCTS & MARKETS TECHNICAL RESOURCES MORE Deprotections Amine deprotection using SiGNa materials effects clean desulfonation and deallylation, utilizing a safe, smooth solution process. SiGNa’s method improves yield and reaction conditions, provides milder conditions and simplifies process purification. BENEFITS Provides a smooth solution process at convenient temperatures Highly selective allowing more options for substrate functionalization No toxic (i.e., mercury) or hazardous (i.e. liquid ammonia) materials needed No special equipment required for handling or processing AVAILABLE PRODUCT LINES ActiveDry ActiveGel Back to Top Desulfurization Due to its finely dispersed metal and high reactivity, SiGNa’s desulfurization method can remove sulfur from a wide range of sulfur species, including ones that are highly aromatic. With this method, desulfurizations can be performed at room temperature and pressure with simpler and safer reaction conditions. BENEFITS Can be performed in either batch or continuous-flow reactor setup Provides a smooth solution process at room temperature and pressure Enhanced selectivity and kinetics of reaction Capable of chemically removing sulfur from highly aromatic sulfur systems AVAILABLE PRODUCT LINES ActiveDry Back to Top Dissolving Metal Reduction Dissolving metal reductions performed using SiGNa’s stabilized reactive metals removes the hazards of alkali metal use and eliminates the need for cryogenic temperatures, high pressures, liquid ammonia, or additional catalysts. Our method improves yields, shortens reaction times, and simplifies workup procedures by enabling a smooth solution process at room temperature and pressure. BENEFITS Enhanced selectivity and kinetics of reaction Hydrogen can be supplied by either homogeneous or heterogeneous sources Performed in either batch or continuous-flow reactor setup in safe solvents By-products are non-hazardous and environmentally friendly AVAILABLE PRODUCT LINES ActiveDry ActiveGel Back to Top Ester Reduction An ester reduction using SiGNa’s materials results in alcohol conversion in high yield under mild reaction conditions. The simple aqueous workup, the quick reaction times, and the mild reaction conditions for this transformation make this new method better than modern methods for ester reductions. BENEFITS Provides a smooth solution process at close to room temperature Highly selective allowing more options for substrate functionalization Avoids reaction workup issues associated with the formation of aluminum salts No special equipment required for handling or processing AVAILABLE PRODUCT LINES ActiveDry ActiveGel Back to Top Hydrogen Generation A chemically-based hydrogen-generating fuel that is lightweight, high in gravimetric energy density, non-toxic and thermally stable. ActiveFuel delivers up to 15.5 wt% H2 with a 50:50 wt% ratio and a higher wt% H2. It reacts quickly with any water solution and provides high-purity, humidified hydrogen. No PEM catalyst poisons or stream diluents are formed that might be detrimental to fuel cell performance. BENEFITS Lightweight fuel cell systems with long runtimes A load-following hydrogen generation process Flexible start/stop capability, either onsite or remotely Elimination of compressed gas or combustible fuels Unlimited fuel storage lifetimes AVAILABLE PRODUCT LINES ActiveFuel™ Back to Top Olefin Isomerization SiGNa’s catalyst material offers a significant process improvement that speeds kinetics and reduces temperature requirements without the need for further processing. This catalyst, which can be implemented in either batch or continuous production runs, offers the ability to increase throughput and reduce the costs associated with large-scale isomerizations. BENEFITS Enhanced selectivity and kinetics of reaction No skeletal rearrangement of the olefin Performed neat in either batch, or continuous-flow, reactor setup with no workup needed By-products are non-hazardous and environmentally friendly Isomerization achieved is random across the carbon chain AVAILABLE PRODUCT LINES ActiveIsom® Back to Top Phosphine Reduction Arylphosphines are readily reduced by SiGNa’s ActiveGel materials providing a convenient method for specialty phosphine synthesis without the need of metal dispersions or liquid ammonia. Unlike traditional methods, SiGna’s methodology allows a broad range of solvents and conditions to be used in the reduction of arylphosphines. BENEFITS Convenient reaction conditions High volume efficiencies Faster reaction kinetics No toxic materials or by-products AVAILABLE PRODUCT LINES ActiveDry ActiveGel Back to Top Wurtz Coupling Carbon bond formations with SiGNa’s materials can be performed in both atom and process efficient syntheses, reducing the cost to the end user. The reaction conditions allow for much cleaner products, safer reactive species and milder conditions. BENEFITS Provides a smooth solution process at room temperature Can be performed in either batch or continuous-flow reactor setup Enhanced selectivity and kinetics of reaction By-products and salts removed through binding to SiGNa’s material AVAILABLE PRODUCT LINES ActiveDry ActiveGel Back to Top Industrial Chemicals PRODUCTS REACTIONS Products & Markets OIL & GAS CHEMICALS Products Applications Technical Resources INDUSTRIAL CHEMICALS Products Reactions Technical Resources Company About Us Our Science Sustainability Leadership Scientific Council Human Resources Technical Resources Brochures Publications Safety Data Sheets Videos Media Contact Purchasing News & Releases Media & Downloads Connect Linkedin Google-plus Twitter Youtube-play Slideshare Smart Science® © 2021 SiGNa Chemistry, Inc. 400 Madison Avenue, 22nd Floor, New York, NY 10017 (212) 933-4101 Terms of Use | Privacy Policy Winner of the Presidential Green Chemistry Challenge Award We use cookies to analyze site usage, provide social media features and assist in our marketing efforts.
