Chemical name: Adduct of boron trifluoride (BF₃) and diethyl ether (O(C₂H5)₂) Trade name: Boron trifluoride Diethyl ether（Etherate） Chemical formula: BF₃x O(C₂H5)₂ Molecular weight: 141,91 g/mol CAS No.: 109-63-7 EINECS No.: 203-689-8 Form supplied and packaging: Supplied in 200 l sheet steel drums with HDPE inner lining and in 60 l metal drums with HDPE inner lining. Supply in small containers. Boron Trifluoride Diethyl etherate Properties: When stored for relatively long periods it can turn dark in color without losing its application-related properties. On dilution with water, hydrolysis ensues with liberation of diethyl ether. A corrosive, highly acidic mixture of boric acid, hydroxyfluoroboric acids and tetrafluoroboric acid is obtained. The vapors released in air are corrosive. Due to its catalytic properties Boron trifluoride Diethyl ether reacts with numerous organic compounds.

Boron Trifluoride Methanol Complex PRODUCT DESCRIPTION Used in the deactylation of acetanilides.It is also used to study the synthesis of amino group containing cyanine dyes of different types and to prepare fatty acid methyl esters. Boron trifluoride-methanol (BF-M) is an esterification reagent. BF-M is a powerful acidic catalyst for the esterification of the fatty acids. It easily cleaves acetylated dyes resulting in free amino groups. BF-M catalyzed trans esterification of vegetable oils forms biodiesel Boron Trifluoride Methanol CAS No.: 373-57-9 Formula: C H3OH.BF3 Quality standards: Appearance: Colorless or light yellow liquid

Non-iron aluminium sulfate Product Description One of the important uses of non-iron aluminum sulfate particles is as a flocculant for the purification of drinking water and wastewater treatment. The iron-free aluminum sulfate particles are easily hydrolyzed formed insoluble precipitates, which help to remove the tiny particles that are not easily filtered in the effective time in drinking water treatment or too small to be precipitated by gravity. non-iron aluminium sulfate Parameter SPEC Inspection result Aluminium oxide（AL2O3）% ≥15.80 Qualified Iron（Fe） % ≤0.005 Qualified （Water insoluble）% ≤ 0.050 Qualified PH (1% water solution） % ≥ 3.0 Qualified Particle size (mm) ≤5 Qualified

Boron Trifluoride Acetic Acid Complex Product Description Boron trifluoride-tetrahydrofuran complex is used as a polymerization initiator and as a dopant in the semiconductor industry. It serves as a reagent for deoxofluorination of alcohols and carbonyls. Further, it is used in the synthesis of methacrylate-PEG-methacrylate-boron trifluoride self-doped gel polymer electrolytes and hydroboration-oxidation of divinylferrocene. In addition to this, it is used as a reagent for the preparation of NK1 receptor antagonists, complex polyketide natural products and selective serotonin reuptake inhibitors.

Also used in the stereoselective synthesis of (-)-Brevisamide. 1,4-Buta0ediol's largest use is within tetrahydrofur (THF) production, used to make polytetramethylene ether glycol, which goes mainly into spandex fibers, urethane elastomers, and copolyester ethers. It is commonly used as a solvent in the chemical industry to manufacture γ- butyrolac and elastic fibers like spandex. It is used as a cross-linking agent for thermoplastic urethanes, polyester plasticizers, paints and coatings. It undergoes dehydration in the presence of phosphori acid yielded teterahydrofuran, which is an important solvent used for various applications. It acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU). It finds application as an industrial cleaner and a glue remover. 1,4-butaediol is also used as a plasticiser (e.g. in polyesters and cellulosics), as a carrier solvent in printing ink, a cleaning agent, an adhesive (in leather, plastics, polyester laminates and polyurethane footwear), in agricultural and veterinary chemicals and in coatings (in paints, varnishes and films). 1,4-Butaediol Preparation Products And Raw materials Raw materials : Formaldehyde-->Nickel-->1,3-BUTADIENE-->A , cetylene-->2,3- Butaedione-->2-Butyne-1,4 , -diol-->Chloroprene-->cis-1,4-Dichloro-2-but , ene-->3- hydroxy-2-methyl propionaldehyde-->DIMETHYL MALEATE-->2-HYDROXYTETRAHYDROFURAN Prepa , ration Products:Tetrahydrofuran-->Gamma Butyrolacton-->Polyurethane foams-- >Triethylene glycol dimethacrylate-->1,4-Dibromobutae-->Poly(but , ylene terephthalate)-->GD visible light curing composite resin-->PolyesterPolyol-->2,3- Dihydrofur , an-->1,4-BUTAEDIOL DIACRYLATE-->4-Hydroxybutyl acrylate-- >Polyvinylpyrrolidone-->Busulf , an-->Pyrrolidine It mainly produces and develops local anesthetics, pharmaceutical intermediates, organic solvents, and steroids and other APIs.
