    1. Basic product information

    English alias: Triethoxyborane; Triethylboratecolorlessliq; Triethyl borate, (Boric acid triethyl ester); Boron ethoxide; Boric acid triethyl ester

    CAS number: 150-46-9

    EINECS number: 205-760-9

    Molecular formula: C6H15BO3

    Relative molecular weight or atomic weight: 145.99

     

    2. Physical properties

    Appearance: colorless transparent liquid. There is a slight smell. Has significant thermal stability. Easy to absorb moisture, easily decomposed into ethanol and boric acid in water. combustible.

    Density: 0.8746 (10 ℃)

    Melting point (℃)】-84.8

    Boiling point (℃): 117.4

    Flash point (℃): 11

    Refractive index: 1.3740

    Dissolution: insoluble in water, decomposes in water to produce ethanol and boric acid.

     

    3. Product Technology

    1. Ethanol and boric anhydride can be prepared by reacting at 80 ℃. Since this product is hydrolyzed in water, water-absorbing agent is added during the reaction to keep the system dry. After the reaction is completed, distillation is exquisite.

     

    2. Manufacturing method:

    In a reaction bottle equipped with a stirrer, reflux condenser, and thermometer, add 460mL of absolute ethanol, and add 75g (1.08mol) of boron oxide powder (2) in batches at a rate to increase the temperature of the reaction solution without refluxing. It is advisable to add it in about 10 minutes. Cool and filter out solid boric acid. The filtrate was fractionated, and the azeotrope of triethyl borate and ethanol was evaporated to about 250mL. It was washed three times with cold concentrated sulfuric acid, and then fractionated, and the fractions at 118 to 120 ° C were collected to obtain 50 g of compound (1) in a 30% yield.

     

    4. Purpose

    1. Used for manufacturing semiconductor components, synthetic organic borides, plasticizers, welding fluxes, etc.

    2. Used in the manufacture of semiconductor components, the synthesis of other organic borides, also used as high-purity raw materials and plasticizers and welding fluxes

    3. Synthesis of other organoboron compounds. High purity boron raw material. Plasticizer. Manufacturing semiconductor components. Welding flux. preservative. Disinfectant. Antiknock agent.

     

    5. Necessary materials for export of triethyl borate

    Cas number: 150-46-9, UN: 1176

    Customs Code HS: 29209090

    Tax rebate: The current tax rebate for triethyl borate is 9%.

    Raw materials: using ethanol and boric anhydride as raw materials.

    It belongs to several types of dangerous goods: At present, triethyl borate belongs to 3 types of dangerous goods.

    Packing: Net weight 200KG / galvanized iron barrel (16 tons in a small cabinet), 1000KG / IB barrel (18 tons in a small cabinet) or 23 tons ISOTANK
