He worked on tartaric acid , lactic acid , pectin , cellulose , chlorophyll and the composition of bones, protein and muscles.
When he was elected to the management of the large glass factory of Saint-Gobain (Compagnie de Saint-Gobain) after Pelouze's death , he undertook experiments to prepare sulfuric acid from gypsum , on the decomposition of hydrochloric acid by air and an investigation of the functions of the gay -Lussac-Tower in the sulfuric acid factory; in particular he discovered the saponification of fats with sulfuric acid for the manufacture of stearin candles .
Other works relate to the glass industry, the production of artificial fertilizers, to the cement, iron and steel industries, as well as to the vegetable fiber and paper manufacture.
