WebEsters can also be derived from inorganic acids. Phosphoric acid forms phosphate esters, e.g. triphenyl phosphate ( O=P (OC6H5)3) and methyl dihydrogen phosphate ( O=P (OCH3) (OH)2) Sulfuric acid forms sulfate esters, e.g., dimethyl sulfate ( (CH3O)2SO2) and methyl bisulfate ( CH3OSO2OH) WebEsters are commonly used in the preparation of artificial flavors or fragrances. Flavors and fragrances may utilize a single ester or a mixture of esters and other substances to duplicate the odor and flavor of a particular fruit. Some esters that smell like common materials that can be prepared in the laboratory are listed in Table 1. H3C C O ...
