What does esterification mean?
- What does esterification mean? A chemical reaction resulting in the formation of at least one ester product. (noun)
What are the general reactants of esterification?
- Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials, and often have a characteristic pleasant, fruity odor. This leads to their extensive use in the fragrance and flavour industry.
Which reaction is the opposite of esterification?
- The opposite of the esterification is called saponification. The main difference between esterification and saponification is that esterification is the production of an ester from a carboxylic acid and an alcohol whereas saponification is the cleavage of an ester back into the carboxylic acid and alcohol. 1. What is Esterification 2.
What is Fischer-Speier esterification?
