WebMaking esters from carboxylic acids and alcohols. Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulphuric acid. Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones containing a benzene ring). Web20 dec. 2024 · Selected distilling strains of S. cerevisiae typically produce a fermented wash at 8–10% v/v ethanol. An interesting raw material for neutral spirit production is cheese whey. This liquid is a by-product of the cheese-making process and is rich in lactose, as well as other nutrients, for yeast fermentation.
