Butyltin tris-(2-ethoxyhexanoate)
Butyltin tris(2-ethylhexanoate) is a clear to pale yellow viscous liquid organotin compound, with good thermal stability and compatibility. It is a high-efficiency catalyst widely used in esterification, transesterification, and polycondensation reactions, and also serves as a stabilizer in certain polymer processing processes. The product has low volatility, excellent catalytic activity, and can significantly accelerate reaction rates, reduce reaction temperatures, and improve product yields and quality.
●Esterification Reactions: Used as a high-efficiency catalyst in the synthesis of various esters (such as phthalate esters, adipate esters, and citrate esters), suitable for the production of plasticizers, lubricants, and flavor and fragrance intermediates.
●Transesterification Reactions: Catalyzes the transesterification of esters and alcohols, widely used in the production of biodiesel, polyester monomers, and other products.
●Polycondensation Reactions: Serves as a catalyst in the polycondensation of diols and dicarboxylic acids (or their esters) to synthesize polyester resins (such as PET, PBT) and polyurethane resins, improving reaction efficiency and product molecular weight.
●Used as a heat stabilizer in the processing of PVC and other halogen-containing polymers, improving the thermal stability and processing performance of the products; also used as a crosslinking catalyst for silicone rubber and epoxy resins.

Handling Precautions
●Operate in a well-ventilated environment, avoid direct contact with skin, eyes, and respiratory tract; wear personal protective equipment (chemical safety goggles, nitrile gloves, and protective clothing) during operation.
●Handle with care to avoid collision, leakage, and splashing; do not mix with strong acids, strong alkalis, oxidants, and food-grade materials.
●Do not eat, drink, or smoke in the operation area; wash hands, face, and other exposed parts thoroughly with soap and water after operation.
●Use dedicated tools and equipment for handling, and clean them thoroughly after use to avoid cross-contamination.
Storage Conditions
●Store in a cool, dry, well-ventilated warehouse, away from fire sources, heat sources, and direct sunlight; the storage temperature should be 5-30℃, avoid high temperature and humidity.
●Keep the container tightly closed to prevent volatilization and moisture absorption; store in a sealed container made of HDPE, PP, or glass.
●Store separately from strong acids, strong alkalis, oxidants, food, beverages, and feed, and mark clearly with product name, CAS number, and hazard signs.
●Shelf Life: 12 months under proper storage conditions; expired products should be re-inspected, and can be used only if they meet the indicators.
