Brief Introduction:
Glycerin, also known as propylene glycol, is a non-toxic, lubricating, odorless, colorless and environmentally friendly substance with a higher density than water. As an important polyol, it is produced in large quantities as a byproduct in the biodiesel industry and is favored in the cosmetics, personal care and food industries for its wide range of uses. Glycerin can be produced by esterification or transesterification to produce glyceryl monostearate (GMS), and further optimized by enzymatic (ENZ), chemical catalytic (CHEM) or autocatalytic (AUT) processes, among which the ENZ method shows significant advantages in economic evaluation, including lower capital investment and higher net present value and return on investment. In addition, glycerol has also been studied for use in drilling fluid formulations to improve technical performance and environmental compatibility. In particular, in scientific research, g-C3N4 nanoparticles were used to test the adsorption of glycerol. The results showed that g-C3N4 has good crystallinity and ordered structure, which is suitable for the degradation of organic pollutants. Its adsorption capacity is 6.5 mg/g, and it exhibits effective visible light absorption and luminescence properties, which makes it have potential application prospects in optoelectronic devices and other fields.

Alcohols
Glycerine is a trihydroxy alcohol, meaning it contains three hydroxyl groups (-OH).
Polyols
It is a type of sugar alcohol because of its multiple hydroxyl groups. Polyols are often used as humectants in food and cosmetics.
Organic Compounds
Glycerine is an organic compound because it contains carbon atoms and is derived from natural sources, such as fats and oils.
Hydrocarbons
Although it is not a pure hydrocarbon, it belongs to the broader category of organic compounds that are related to hydrocarbons.
Moisturizers
Glycerine is widely used in skincare products as a humectant due to its ability to retain moisture.
Carbohydrates
It is related to carbohydrates because it can be considered a polyalcohol derived from sugar-based compounds.
