Ester

酯是由与醚键相邻的羰基组成的化合物。 它们是通过使含氧酸与羟基化合物如醇或苯酚反应得到的。 酯通常衍生自无机酸或有机酸,其中至少一个-OH基团被-O-烷基取代,最常见的是羧酸和醇。 也就是说,通过将酸与醇缩合形成酯。 酯类是普遍存在的。 大多数天然存在的脂肪和油是甘油的脂肪酸酯。 低分子量的酯通常用作香精,并在精油和信息素中发现。 磷酸酯形成DNA分子的骨架。 硝酸酯,如硝酸甘油,以其爆炸性质而闻名,而聚酯是重要的塑料,单体通过酯部分连接。 Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH group is replaced by an -O-alkyl group, and most commonly from carboxylic acids and alcohols. That is, esters are formed by condensing an acid with an alcohol. Esters are ubiquitous. Most naturally occurring fats and oils are the fatty acid esters of glycerol. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties.
