One of them are the esters of orthocarboxylic acids. Those esters have the formula RC(OR′) 3, where R stands for any group (organic or inorganic) and R ′ stands for organyl group. For example, triethyl orthoformate (HC(OCH 2 CH 3) 3) is derived, in terms of its name (but not its synthesis) from esterification of orthoformic acid (HC(OH) 3 ...
An example of an ester formation is the substitution reaction between a carboxylic acid (R−C(=O)−OH) and an alcohol (R'OH), forming an ester (R−C(=O)−O−R'), where R and R′ are organyl groups, or H in the case of esters of formic acid.
Esters with the general formula R 1 SO 2 OR 2 are called sulfonic esters.Individual members of the category are named analogously to how ordinary carboxyl esters are named.For example, if the R 2 group is a methyl group and the R 1 group is a trifluoromethyl group, the resulting compound is methyl trifluoromethanesulfonate.
In organic chemistry, a nitrate ester is an organic functional group with the formula R−ONO 2, where R stands for any organyl group. They are the esters of nitric acid and alcohols. A well-known example is nitroglycerin, which is not a nitro compound, despite its name.
IUPAC states "The esters are often called urethanes or urethans, a usage that is strictly correct only for the ethyl esters." [ 44 ] But also states, "An alternative term for the compounds R2NC(=O)OR' (R' not = H), esters of carbamic acids, R,NC(=O)OH, in strict use limited to the ethyl esters, but widely used in the general sense". [ 45 ]
Carboxylate esters have the general formula RCOOR ... For example, the pK a value of acetic acid is 4.8, while ethanol has a pK a of 16. Hence acetic acid is a much ...
acetate ester. Acetate esters have the general formula CH 3 CO 2 R, where R is an organyl group. The esters are the dominant forms of acetate in the marketplace. Unlike the acetate salts, acetate esters are often liquids, lipophilic, and sometimes volatile.
The esters include ethyl acetate, n-butyl acetate, isobutyl acetate, and propyl acetate. They are typically produced by catalyzed reaction from acetic acid and the corresponding alcohol: CH 3 COO−H + HO−R → CH 3 COO−R + H 2 O, R = general alkyl group. For example, acetic acid and ethanol gives ethyl acetate and water.
