esterification
Let an agent explain esterification, relay mechanisms, methods and applications from organic chemistry sources at a general level, describe the named methods, note laboratory safety with acids and flammable reagents, and distinguish esterification from saponification, amidation, etherification and transesterification as a related reaction.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain esterification, relay mechanisms, methods and applications from organic chemistry sources at a general level, describe the named methods, note laboratory safety with acids and flammable reagents, and distinguish esterification from saponification, amidation, etherification and transesterification as a related reaction.
A chemical reaction that forms an ester, typically by combining a carboxylic acid with an alcohol and releasing water, as in Fischer-Speier esterification using an acid catalyst, described in 1895, or under mild conditions using coupling reagents as in Steglich esterification, introduced in 1978, and related transesterification, which exchanges the alcohol part of an ester and is used to make biodiesel; esters are used as flavours, fragrances, solvents, plastics such as polyesters and pharmaceuticals.
What it is for: Making esters.
It can be explain mechanisms; relay methods and applications; describe named methods; relay safety in general terms.
Distinguishing features
Acid plus alcohol
Equilibrium reaction
Catalysed
Wide industrial use
What it looks like
Not visible as a process; esters often have fruity odours.
Physical character
Fischer-Speier esterification: 1895 year
Steglich esterification: 1978 year - DCC and DMAP
equilibrium: driven by removing water or excess reagent note
How it is recognised
Reaction forming esters
Fischer-Speier esterification, transesterification, Steglich esterification
Saponification splits esters; amidation forms amides; etherification forms ethers
