数据库记载的用途

  • Artificial sweetening agent, prohibited by FDA for use in foods.
  • Food Additives -> SWEETENER -> JECFA Functional Classes
  • ... Produced from the addition of potassium cyanate to p-phenetidine hydrochloride in aqueous solution at room temperature or from mixing urea and p-phenetidine hydrochloride to a mixture of hydrochloric acid and glacial acetic acid.
  • Made by treating p-phenetidine with phosgene and then with ammonia.
  • Dulcin achieved some practical importance as a sweetener, despite safety concerns. It was blended with saccharin or sodium saccharin in order to mask the aftertaste of saccharin. As some dulcin metabolites were considered potentially hazardous, it is now banned in most countries.
  • Compared with dilute sucrose solutions, it is approximately 250 times sweeter. Sweetness characteristics are good.
