They vary - but nearly always involve reflux followed by removal of water often with the aid of an azeotropic solvent. An acid catalyst such as concentrated sulfuric acid is often employed but titanates and other catalysts have also been used.
Esters do not react with sodium carbonate under normal conditions because esters are relatively stable compounds and do not readily undergo chemical reactions with mild bases like sodium carbonate. If a reaction were to occur, it would likely require more drastic conditions or a catalyst.
Such compounds are mostly esters.
Esters are neutral compounds
Fats are esters of fatty acids and glycerin (propane-1,2,3-triol).
Yes they have if they are esters of Carboxylic acids. Eg: Methyl acetate has carbonyl in its middle : H3C-(C=O)-O-CH3

heat,oxygen,fuel source
sunlight, water and air .....
Such compounds are mostly esters.
No different chemical make up.
Probably when you take a sugar with alcohol components (-OH), turn them into O- ions by using a basic conditions (say NaOH) and then alkalizing them to form esters (say CH3I). That would replace all alcohols with (-OCH3 esters). "esterification of sugars"
Esters are flavorings. They are also used with perfumes.
Esters are neutral compounds
Esters are compounds that form when organic acids react with alcohols.
Yes, sodium borohydride can reduce esters to alcohols.
Yes, sodium borohydride can reduce esters to alcohols.
Esters lack hydrogen atoms attached directly to highly electronegative atoms like oxygen or nitrogen, which are necessary for forming hydrogen bonds. In esters, the hydrogen atoms are bonded to carbon atoms, making them unable to participate in hydrogen bonding with other esters.
