Overview:Dibutyltin diacetate is a light yellow or colorless transparent liquid with an odor of acetic acid.Product Name: Dibutyltin diacetate 1067-33-0English name: Dibutyl tin diacetateAlias: dibutyl tin diacetate, dibutyl stannane diacetate; bis (acetoxy) dibutyl stannane; dibutyl tin diacetate; dibutyl tin acetate; di-n-butyl tin diacetate; dibutyl tin acetateProduct designation: DBTDACAS number: 1067-33-0Molecular formula: C12H24SnO4Chinese name dibutyltin diacetateForeign name Dibutyl tin diacetateNickname dibutyltin diacetateCA registration number 1067-33-0Molecular formula: (C4H9)2Sn(OOCCH3)2Molecular weight: 351Specific gravity (H2O=1): 1.3Melting point: 10℃CAS 1067-33-0 Dibutyl tin diacetatePhysical properties:Molecular formula: (C4H9)2Sn(OOCCH3)2Molecular weight: 351.0Specific gravity (H2O=1): 1.30Melting point: 10℃Quality index: Appearance: colorless or light yellow transparent liquid Sn content: 32.5±0.5%Relative density (25℃): about 1.30Tin content: 32.0-33.8%Chemical properties:Melting point: 7-10 °C (lit.)Boiling point: 142-145 °C 10 mm Hg(lit.)Density: 1.32 g/mL at 25 °C(lit.)Vapor density: 12 (vs air)Vapor pressure: 1.3 mm Hg (25 °C)Refractive index: n20/D 1.471 (lit.)Flash point: >230 °FWater solubility: insolubleCAS database: 1067-33-0 (CAS DataBase Reference)NIST: Dibutyltin diacetate (1067-33-0)EPA: Stannane, bis(acetyloxy)dibutyl-(1067-33-0)use:Colorless or light yellow transparent liquid, solid below 10℃, then semi-solidGel catalyst, mainly used as a room temperature silicone rubber curing catalyst, especially suitable for deacetic acid type silicone products; it is characterized by a faster catalytic rate than dibutyltin dilaurate, and can be used for polyurethane elastomers and sprayed rigid polyurethane foam , Hard foam high resilience molded foam, etc. In order to reduce its odor of acetic acid, it can be used in combination with dibutyltin dilaurate, usually using dibutyltin diacetate: dibutyltin dilaurate is 1:9 or 2:8. This product should be capped immediately after use. It is easily hydrolyzed when exposed to air, and solids precipitate out of the bottle mouth. It can also be used as a catalyst for polyurethane coatings.storage:It should be kept dry during storage, and the temperature should be above 10℃. The crystals are precipitated below 10℃, which will not affect the use effect after heating and melting.transport:Store in an airtight container in a cool, dry place. The storage place must be locked, and the key must be handed over to the technical experts and their assistants. The place of storage must be far away from oxidant and water source.General-purpose plastic and plastic-sprayed iron drums or glass containers are packaged and transported in accordance with general chemical management regulations.package:Packing: It should be packed in glass containers, plastic containers, and metal containers resistant to chlorine corrosion, sealed and stored. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash it before reuse. Maintain good hygiene habits.
