Dibutyltin dilaurate Chemical Properties,Uses,Production
Organic tin additive
Dibutyltin dilaurate is an organic tin additives, and can be soluble in benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether and other organic solvents and all industrial plasticizers, but insoluble in water. Multipurpose high-boiling organic tin catalyst circulation of dibutyltin dilaurate are usually specially treated liquefaction, and at room temperature as a pale yellow or colorless oily liquid, when low temperature as white crystals, and it can be used for PVC additives, it also has excellent lubricity, transparency, weather resistance, and better resistance for sulfide pollution. It can also uesd the stabilizer of the soft transparent products and efficient lubricants in hard transparent products, and can also be used acrylate rubber and rubber carboxyl crosslinking reaction, the catalyst of synthesis of polyurethane foam and polyester synthetic, and RTV silicone rubber.
The above information is edited by the chemicalbook of Wang Xiaodong.

Chemical properties
It is pale yellow flammable liquid, and soluble in acetone and benzene, can not dissolve in water.

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.

Production method
It is condensed by DBTO and lauric acid at 60℃. After condensation, vacuum dehydration, cooling, pressure filtration derived products.

Stimulus data
Skin-rabbit 100 mg/24 hours moderate.

Flammability hazard characteristics
Combustible fire.

Storage Characteristics
Treasury should be ventilated and low-temperature drying; and should transport separately with food materials.

Extinguishing agent
Carbon dioxide, sand, water, foam.

Occupational standards
TWA 0.1 mg (Sn)/cubic meter; STEL 0.2 mg (Sn)/cubic meter.

Chemical Properties
yellow liquid

Uses
PU catalyst, RTV silicone rubber

Uses
Stabilizer for polyvinyl chloride resins. Catalyst for curing certain silicones.

Uses
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.

Uses
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.

General Description
Clear yellow viscous liquid.

Air & Water Reactions
Dibutyltin dilaurate may be sensitive to air or heat. . Insoluble in water.

Reactivity Profile
Dibutyltin dilaurate is strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents.

Fire Hazard
Dibutyltin dilaurate is combustible.

Safety Profile
Poison by ingestion and intraperitoneal routes. A skin and eye irritant. Avoid the vapor produced by heating. Combustible when exposed to heat or flame; reacts with oxidizers. When heated to decomposition it emits acrid smoke and fumes. See also TIN COMPOUNDS

Toxics Screening Level
The initial threshold screening level (ITSL) for dibutyl tin dilaurate is 5 μg/m3 (8-hr averaging time).
