Vanillin synthesis

CATALYST-FREE VANILLIN PRODUCTION

Vanillin is the main component of natural vanilla. It is an important flavoring agent and is often used in the food, beverage, perfume and pharmaceutical industries.

More environmentally friendly alternative

To date, vanillin has largely been produced synthetically using petroleum-based raw materials that generate chemical waste. A more environmentally friendly alternative is vanillin production based on biomass-derived feedstock. The transformation of biomass into fuels and chemicals is becoming increasingly popular to mitigate the current global warming trend and diversify energy sources.

Mechanical force

This mechanochemical reaction benefits from the input of mechanical and thermal energy as well as pressure activation. It enables a novel approach to vanillin synthesis without the use of any catalytic system.

Faster reaction

By combining these unique properties, the synthesis in our DYNO-MILL MULTI LAB and DYNO-MILL RESEARCH LAB could be carried out in less time and at lower process temperatures.

Better quality

The combination of continuous flow and mechanochemistry led to excellent results in terms of conversion, selectivity and yield of vanillin. The results were achieved in a lab and pilot-scale machine.

Scalability

The use of a DYNO-MILL enables a continuous process compared to the discontinuous process of the conventional batch heating process. The main advantage of a continuous process is the possibility of scaling up to industrial scale, which means a completely new perspective for vanillin production.

Alternative to petroleum-based compounds

Although more than 12’000 tons of vanillin are produced per year, only less than 1% is natural vanillin, while the remainder is synthesized through chemical processes. This research using DYNO-MILL technology was conducted with chemicals derived from biomass feedstocks.
