C3H8O3 is the Molecular Formula of Glycerine
In chemistry a molecular formula indicates every single atom and its numbers in a chemical compound. Hence the molecular formula C3H8O3 simply says that there are three carbon (C) atoms, eight hydrogen (H) atoms and three oxygen (O) atoms in this compound.
This molecular formula on its own does not indicate how the atoms interact with each other or whether bonding occurs between them.
Production and Chemical Properties of C3H8O3
C3H8O3 glycerine is present as the backbone in all fats. Originally, it was generated during the saponification of animal fats. Glycerine is also a by-product from the production of biodiesel. Furthermore, it is produced petrochemically from propene. In addition, it can also be produced through fermentation. Here yeasts switch to glycerin production if sulphite is added.
Glycerine is odorless, viscous, and attracts water. It melts at a temperature of 18.2 °C, becomes liquid at 20 °C, and its boiling point is 290 °C. At temperatures below its melting point, glycerol solidifies into crystals. It has a density of 1.26 g/cm³. It is readily soluble in alcohol and water. Under the effect of heat, it forms white vapor. If the process takes place during deoxygenation, it disintegrates to aldehyde acrolein; this toxic substance is also known as acrylaldehyde.
