The aim of this study is to clarify the functional mechanism of saccharin as a grain refiner in order to realize which functional group of this molecule works as a grain refiner and causes enhancement of properties. Additionally, methanol can be used to manufacture formaldehyde, which is employed in the production of plastics, paints, and other useful substances. Saccharin (C6H4SO2CON) Water (H2O) Water (H2O) -Organic compounds always contain carbon and hydrogen, and they are typically structurally complex. It is indigestible in the human body but digestible by many microorganisms, including microorganisms found in the digestive tracts of many herbivores. There are a number of functional groups that contain a carbon-oxygen double bond, which is commonly referred to as a carbonyl. Saccharin - Wikipedia Surf.
