nounməˈleɪɪkməˈlēik

A crystalline acid made by distilling malic acid, used in making synthetic resins.
〔化〕马来酸
Chemical formula: HOOCCHCHCOOH
Example sentencesExamples
- Owing to the conducive positioning of the carboxyl groups in cis-butenedioic acid, the acid readily forms an internal anhydride, whereas the trans acid does not.
- Moreover the molecules of maleic acid are polar and are easily hydrated by the polar water molecules.
- Through this procedure, both maleic acid and glyoxal were converted to glyoxylic acid.
- If released into water, maleic acid will probably biodegrade based on the results of screening studies.
- Citric acid, maleic acid, and butanetetracarboxylic acid are the three agents used most often.

Origin

Mid 19th century: maleic from French maléique, alteration of malique (see malic acid).
