Augustin-Pierre Dubrunfaut

from Wikipedia, the free encyclopedia

Augustin-Pierre Dubrunfaut (born September 1, 1797 in Lille , † 1881 in Bercy near Paris ) was a French chemist who was known for inventions in the sugar industry and in the chemistry of fermentation .

Dubrunfaut studied at the Collège de Lille and in Paris. He worked in a sugar refinery and was professor at the Ecole de Commerce de Paris from 1825 to 1830 . In 1827 he founded his own school in Bercy , where he taught the manufacture of sugar and the distillation of brandy .

Dubrunfaut was the first to describe the mutarotation of sugar solutions in 1846 . The specific rotation of the polarized light changes over time in freshly made solutions of sugar in water. He developed a process for the production of sugar from the molasses residue, which was later improved by others to such an extent that it was widely used as the Strontian process for many years .
