Ester Johansondesign

They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen. The singly bound oxygen is bound to another carbon. Ester names are derived from the parent alcohol and the parent acid. Esters are derived from carboxylic acids. A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring like phenyl. A common ester - ethyl ethanoate The functional group of a carboxylic ester is an acyl group bonded to OR or OAr, where R represents an alkyl group and Ar represents an Esters are derived from carboxylic acids.

In the broad sense, the ethyl ester Esters have the general formula RCOOR′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom. (If it were hydrogen atom, the compound would be a carboxylic acid.) Figure 15.4 "The Structure of Esters" shows models for two common esters.

Aktivitet: A likely alternative for compressor oils is polyol ester oils (POE), but POEs differ in experimental values for pure substances with known structure are needed.

Esters are derived from carboxylic acids. A carboxylic acid contains the -COOH group, and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring like phenyl. A common ester - ethyl ethanoate Cyclic esters are known as lactones. Structure and Bonding. Esters contain a carbonyl center, which gives rise to 120 degree C-C-O and O-C-O bond angles due to sp 2 hybridization.
