Useful:

• Canonical SMILES: CCCCCCCCCCCC(=O)[O-].CCCCCCCCCCCC(=O)[O-].CCCC[Sn+2]CCCC
• Uses: It can be used as PVC heat stabilizers, and it is the earliest used varieties in organotin stabilizers, heat resistance is less than tributyltin maleate, but it has excellent lubricity, weather resistance and transparency can be ok, and it has good compatibility with plasticizers, non-blooming, non-sulfide pollution, no adverse effects on heat sealing and printability. For it is liquid at room temperature, so the dispersion in plastic is better than solid stabilizer.The product is mainly used in soft transparent products or semi-soft products, generally in an amount of 1-2%. In hard products, the product can be used as lubricant, and when used with maleic acid organic tin or thiol-containing organic tin can improve the fluidity of the resin material. Compared with other organic tin, the goods early color large will cause yellow discoloration.The product can also be used as catalysts of synthesizing polyurethane, the curing agents of silicone rubber. In order to enhance the thermal stability, transparency, compatibility with resins, as well as improve the impact strength for hard products and its other properties, now it has developed a number of modified varieties. Lauric acid and other fatty acids is generally added in the category of pure, the epoxy ester or other metal soap stabilizer is also added in. The product is toxic materials. Rat oral is LD50 of 175mg/kg. Stabilizer for polyvinyl chloride resins. Catalyst for curing certain silicones. Di-n-butyltin dilaurate is used as a catalyst for the production of polyurethanes as well as for the transesterification reactions. It is involved in the vulcanization of silicones and a stabilizer in polyvinyl chloride (PVC). It acts as a rust inhibitor for polyurethanes, polyols, silicones and as a fuel additive. Dibutyltin dilaurate has been used as a catalyst in a protocol for the covalent attachment of poly(ethylene glycol) (PEG) to silicon oxide to form a hydrophilic non-fouling surface. It can also be used as a catalyst in the preparation of polymers by reacting hydroxyl-terminated macromonomers and aliphatic diisocyanates.
• Production method: It is condensed by DBTO and lauric acid at 60℃. After condensation, vacuum dehydration, cooling, pressure filtration derived products.
