OverviewSodium tert-butoxide, also known as the third Sodium butoxide, English name Sodium tert-butoxide, white crystal, molecular formula C4H9NaO, molecular weight of 96.10, its stable nature at room temperature and atmospheric pressure, slightly harmful to water, used as intermediates in organic synthesis, pharmaceutical intermediates; Or as a strong alkali is widely used in chemical industry, medicine, pesticides and organic synthesis in the condensation, rearrangement and ring opening reaction, therefore, sodium tert-butoxide more and more by the fine chemical and pesticide, pharmaceutical industry.
Basicsodium tert-butoxide is an organic compound with chemical formula (CH3) 3con A, which is a strong base and has weak nucleophilic property, the chemical reaction is similar to potassium tert-butoxide.
Ansökansodium tert-butoxide white crystal, as a strong base widely used in chemical, pharmaceutical, pesticide and organic synthesis of condensation, rearrangement and ring-opening reactions. Stable under normal temperature and pressure, avoid strong reducing agent, moisture, air, acid contact. There is little harm to water, so as to avoid exposure of undiluted or large amount of products to groundwater, water channels or sewage systems; If there is no government permission, do not discharge the materials into the surrounding environment. Used as organic synthesis intermediates, pharmaceutical intermediates; As a strong base is widely used in chemical, pharmaceutical, pesticide and other organic synthesis of condensation, rearrangement and ring opening reaction.
preparationsodium tert-butoxide is synthesized by using toluene or heptane as the solvent of the reaction system according to the following reaction formula, reflux condenser and thermometer in a 500mL reactor, add 240mL of toluene or heptane (moisture content less than 0.04%), add 9.8g 99% sodium amino acid (about 0.25mol) and 19.0g of 99% tert-butyl alcohol (about 0.254mol), the molar ratio of sodium amino acid and tert-butyl alcohol is 1:1.015, fully stirred to dissolve it completely, heated to 70 C to start the reaction, the released ammonia gas is absorbed with water or alkali solution, and the reaction is heated to 100~110 ℃ and then kept for 1H to stop the reaction. After the reaction is sufficient and complete, the reactants are cooled, atmospheric distillation of most of the reaction medium and reaction slightly excessive tert-butyl alcohol, and then vacuum distillation of the remaining small amount of reaction medium to obtain white solid powder about 25g, product content by acid-base titration analysis of more than 99%.
Useas a strong base, it is widely used in condensation, rearrangement and ring opening reactions in chemical, pharmaceutical, pesticide and other organic synthesis.
used in organic synthesis
sodium tert-butoxide is used as an intermediate in organic synthesis and a pharmaceutical intermediate.
