说明

马来酸是一种不饱和有机二元酸丁烯二酸的顺式异构体。马来酸显示典型的烯烃和羧酸反应。酸基的商业上重要的反应包括用二醇酯化成聚酯和脱水成酸酐。双键参与转化为富马酸、磺基琥珀酸和马拉硫磷。

马来酸已被用作锂离子电池的高性能有机负极材料。据报道,In 具有 ca 的超高可逆容量。在 46.2 mAg-1 电流密度下为 1500 mAhg-1,在 46.2 Ag-1 电流密度下具有相对较高的 570.8 mAhg-1 容量。当在 2.31 Ag-1 的高电流密度下循环时,循环 500 次后容量保持率为 98.1%。

马来酸已用于构建用于电池和燃料电池研究的聚合物固体电解质。据报道,基于马来酸的聚合物共混物通过抑制结晶来增加基于 PEO 的聚合物固体电解质的离子电导率。

马来酸也被用于制造超溶胀丙烯酰胺 (AAm)/马来酸 (MA) 水凝胶,通过在以 MA 作为共聚单体的 AAm 水溶液中与一些多功能交联剂(如三羟甲基丙烷三丙烯酸酯和 1,4-丁二醇二甲基丙烯酸酯)进行自由基聚合。在该水凝胶体系中,阳离子染料的吸收随着 AAm/MA 水凝胶中 MA 含量的增加而增加。

一般描述

Maleic acid is the cis-isomer of butenedioic acid, an unsaturated organic dibasic acid. Maleic acid shows reactions typical of both olefins and carboxylic acids. Commercially important reactions of the acid groups include esterification with glycols to polyesters and dehydration to the anhydride. The double bond is involved in conversions to fumaric acid, to sulfosuccinic acid, and to Malathion.
 

应用

Maleic acid has been adopted as a high performance organic anode material for lithium ion batteries. In has been reported to have an ultrahigh reversible capacity of ca. 1500 mAhg–1 at 46.2 mAg–1 current density, and a relatively high capacity of 570.8 mAhg–1 at current density of 46.2 Ag–1. When cycled at high current density of 2.31 Ag–1, a capacity retention of 98.1% was obtained after 500 cycles.
Maleic acid has been used in constructing polymeric solid electrolytes for battery and fuel cell research. Maleic acid based polymer blend were reported to increase the ionic conductivity of PEO basd polymer solid electrolytes by suppressing crystallization.
Maleic acid has also been used to make superswelling acrylamide (AAm)/maleic acid (MA) hydrogels by free radical polymerization in aqueous solution of AAm with MA as comonomer with some multifunctional crosslinkers such as trimethylolpropane triacrylate and 1,4-butanediol dimethacrylate. In this hydrogel system, the uptake of cationic dye increased with an increase of MA content in the AAm/MA hydrogels.
