Decyltributylphosphonium Bis((Trifluoromethyl)Sulfonyl)Imide belongs to the phosphonium family of ionic liquids. In the world of specialty chemicals, this compound draws interest for applications where high thermal stability and unique solvation abilities matter. Built from a decyl tributylphosphonium cation paired with the bis((trifluoromethyl)sulfonyl)imide anion, this material shows up in research papers and production sites aiming to push boundaries in material fabrication, electrochemistry, and advanced separations. Every batch of raw material carries importance, since precise chemical structure determines overall application success.
Its molecular formula is C22H46F6NO4P S2. The decyltributylphosphonium part consists of a phosphorus atom bonded to three butyl chains and one decyl chain, making it a bulky, hydrophobic cation. The bis((trifluoromethyl)sulfonyl)imide anion features two trifluoromethyl groups attached to sulfonyl groups linked through an imide, supplying excellent thermal and chemical resistance. The overall structure, P(C10H21)(C4H9)3[TFSI], brings low viscosity, a factor that stands out in practical handling and processing.
This compound is often seen as a clear to faintly yellowish liquid at room temperature, though under some conditions, it can form flakes or powdery solid when cooled or exposed to dry environments. Its density hovers around 1.15 to 1.23 g/mL at 25°C, depending on purity and exact composition. Viscosity remains relatively low for an ionic liquid, aiding smooth transfer and accurate measurement down to the last milliliter. In crystal form, it reflects a well-ordered structure, but most industries favor the liquid or semi-solid state for convenience. With solubility that veers toward organic solvents while resisting water, it slips into many formulations as either a base material or as an additive. Laying eyes on it, lab staff always check for clarity and absence of cloudiness—a sign of high raw material quality.
Suppliers list this chemical under the HS Code 2920909090, tying it to the class of other organic compounds containing phosphorus. Reliable batches demand narrow impurity profiles, typically less than 0.1% for water and very low halide contamination, as dictated by production standards in electronics and chemical synthesis. It comes packaged as a liquid in sealed jars, sometimes as a powder or flakes, but rarely as pearls or granules due to its physical nature. Researchers I’ve worked with look for high purity every time, knowing that impurities can disrupt ionic conductivity or reactivity. Whether used to dissolve polymers, tweak electrolyte performance in batteries, or drive chemical separations, this ionic liquid sets the tone for what comes next in a process.
Decyltributylphosphonium Bis((Trifluoromethyl)Sulfonyl)Imide brings attention to both chemical safety and potential hazards. Standard lab protocols apply: gloves, safety goggles, and adequate ventilation are non-negotiable when handling. In my experience, accidental skin contact feels slippery and may lead to mild irritation, though it does not generally provoke severe reactions at ambient temperatures. Inhalation of vapors and repeated contact can lead to respiratory or skin irritation. Safety data notes a low acute toxicity profile but flags longer-term exposure risks. The presence of fluorinated groups demands careful disposal practices since breakdown products, especially under thermal stress, can form harmful compounds. Material Safety Data Sheets (MSDS) call for containment of spills, diligent waste collection, and avoidance of open flames. Keep away from acids and strong oxidizing agents, since uncontrolled reactions can occur. Chemical fume hoods provide protection in any experimental setup.
Industry often turns to ionic liquids like this phosphonium compound when old-school solvents or salts don’t cut it. In the lab and on the pilot line, this material works in lithium battery electrolytes, helping stabilize charges for better safety and performance. Its compatibility with a wide range of materials makes it a go-to for custom solvent systems, including extraction and separation tasks in green chemistry. I’ve noticed more companies treat it as a paving stone for replacing volatile organic solvents, loving its low vapor pressure and high thermal window. Still, the higher price point compared to traditional solvents draws careful purchasing decisions, pushing teams to maximize each drop bought. Purity, reliable sourcing, and handling expertise raise the odds of success. As part of the drive for safer, greener chemical manufacturing, Decyltributylphosphonium Bis((Trifluoromethyl)Sulfonyl)Imide points the way to next-generation industrial chemistry—while demanding up-to-date safety practices and full transparency in raw material supply chains.
