3,4-Dimethylbenzaldehyde Chemical Properties, Uses, Production
Chemical Properties
Clear colorless to yellowish liquid
Uses
3,4-Dimethylbenzaldehyde is used as an additive for resins, agricultural intermediate and for flavor and fragrance, nucleation transparent agent.
Definition
ChEBI: 3,4-Dimethylbenzaldehyde is a carbonyl compound.
General Description
3,4-Dimethylbenzaldehyde (3,4-DMB) is a benzaldehyde derivative. It is the OH radical initiated oxidative degradation product of trimethylbenzene. The rate coefficient of the gas-phase reaction between 3,4-DMB and OH radical is 24.6±4.0×10-12cm3molecule-1s-1. The vibrational analysis of 3,4-DMB based on FT-IR spectra, FT-Raman spectra, ab initio and density functional theory (DFT) calculations have been reported. It is formed as an intermediate during the transformation of furfural into gasoline-range fuels using ZSM(Zeolite Socony Mobil)-5-based catalysts.
