In 1816, the Academy of Marie Thérèse, reestablished by the King of the Netherlands, announced a competition for Belgian factories on the uses of water vapor as a heating method.

His work, crowned and published in 1818, was the first memoir from the State University of Leuven's science section established by Jean-Baptiste Van Mons in 1819.

That same year, De Hemptinne patented a machine for simultaneously beating and rinsing cotton canvas, but its need for frequent repairs led to its abandonment.

[6] He was appointed to the steering committee of the 1830 Exposition des produits de l'industrie belge in the wake of the Belgian Revolution.

De Hemptinne, Poelman-Hamelinck, Eugène Prévinaire, and Seny introduced the perrotine printing machine to Belgium in 1834, allowing three colors to be applied at once, replacing the wooden board.

[5] Auguste de Hemptinne presented his invention, a device for inhaling ether, to the Royal Academy of Medicine of Belgium in February 1847.

Auguste-Ferdinand de Hemptinne, the eldest child born in 1819, eventually took over the chemical products factory in Molenbeek.
