Questions And Answer | Back Directory | [Description]
Diethyl succinate is obtained by the direct esterification of a carboxylic acid and an alcohol in the presence of concentrated H2SO4 in benzene solution. It has a faint, pleasant odor. It occurs naturally in apple, raspberry, cognac, rum, whiskey, cider, sherry, plum brandy, apple brandy, grape brandy, cherry brandy, cocoa, arrack and red, white, port, strawberry and sparking wines.
It is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, frozen dairy, hard/soft candy, gelatins, and puddings.
