4-tert-Butylbenzaldehyde Chemical Properties,Uses,Production
Uses
Used for preparing isoxazolyl penicillin derivatives. 4-tert-Butylbenzaldehyde is suitable for use in a kinetic study to evaluate the kinetic constants (KI) for inhibition of mushroom tyrosinase by 4-substituted benzaldehydes. It is also an important intermediate for the synthesis of medicines, dyes, flavor and fragrance compounds.

General Description
4-tert-Butylbenzaldehyde is an important intermediate for the synthesis of medicines, dyes, flavor and fragrance compounds. It is reported to be formed during the partial oxidation of 4-tert-butyltoluene by hydrogen peroxide in glacial acetic acid, catalyzed by bromide ions in combination with cobalt(II) acetate or cerium(III) acetate. Schiff base reaction between 4-tert-butylaniline and 4-tert-butylbenzaldehyde in ethanol has been carried out on-chip in the matrix assisted laser desorption ionization (MALDI) chamber, the formed imine was detected in real time.
Synthesis
At present, the synthesis methods of p-tert-butyl benzaldehyde include chemical oxidation, oxygen (air) oxidation, electrochemical oxidation and benzyl halide hydrolysis. Oxygen (air) liquid-phase oxidation is currently the most interested in a method, does not consume more expensive oxidizing agent, and production capacity, environmental pollution is small, is currently the development potential of the method.
