Reference of 624-95-3 , The common heterocyclic compound, 624-95-3, name is 3,3-Dimethylbutan-1-ol, molecular formula is C6H14O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
[00066] Example V represents an oxidation in which the KBr co-catalyst and the NaHCO3 buffer were removed and they were replaced with Na2B4O7-Zr(acetate)2 additive. [00067] 16.9 g of 3,3-Dimethyl-1-butanol (117.3 mmol) and 0.0765 g MeO TEMPO (0.411 mmol) are charged in a jacketed glass reaction flask as in Example I. Sodium borate (0.380 g, 1.0 mmol) and Zr(acetate)2 (0.2 g solution, 0.1 mmol) are dissolved in water (12.0 cc) and the aqueous solution is added to the stirred organic fraction at 1000 RPM in the reaction flask. The stirred suspension is cooled to 0 C. and the emulsion is re-adjusted to pH=8.4 using 50% solution of CH3COOH. When the temperature of the reactants reached 0 C., 75.5 g (122 mmol) of 12.1% aqueous NaOCl solution are pumped in via a gas-tight syringe over 90 minutes (The pH of the bleach solution was adjusted to 10 using 50% aqueous CH3COOH). During the bleach addition the pH was maintained at 8.3-8.4 levels using few drops of 50% aqueous CH3COOH. The reaction mixture is stirred for an additional 120 min at 0 C. and the organic layer is sampled for GC assay. The reaction in this second stage was kept at pH 8.4 by addition of 0.2-0.25 cc aqueous solution of NaOH (50% concentration). The yield of 3,3-dimethylbutyraldehyde is 95.0% at 60 min and 93.0% at 90 min reaction time
The synthetic route of 624-95-3 has been constantly updated, and we look forward to future research findings.
