Abstract:
In this study, a one-step method for producing phytosteryl phenolates, namely phytosteryl cinnamate and ferulate, has been successfully developed and their chemical structures were confirmed by FT-IR, MS and NMR. The highest yield of phytosteryl ferulate (85.7%) was obtained at 100 °C for 2 h after optimization. A Lewis acid catalyst scandium triflate was selected as the catalyst, and it turned out that it could be reused for at least five times without significant loss of activity. Meanwhile, it has been demonstrated that the solubility of phytosteryl phenolates in soybean oil was much higher than in both phenolic acid and phytosterol, which was conducive to expand their applications in oil-based food. The research finding helps realize convenient, green and efficient synthesis of phytosteryl phenolates.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and...

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
