Meaning of "excess thionyl chloride"
Excess thionyl chloride refers to the surplus or surplus amount of thionyl chloride, a chemical compound commonly used in organic synthesis, particularly for the conversion of carboxylic acids to acid chlorides. The phrase implies that more thionyl chloride is used than what is required for a particular chemical reaction or process. Excess thionyl chloride can potentially result in increased reaction rates, higher yields, or undesired by-products
