Description about maleic acid, also known as cis-butenedioic acid chemical formula is c 4 h 4 o 4 its cas number is 110-16-7 it is a dicarboxylic acid organic compound, which is a molecule with two carboxyl groups. Maleic and fumaric acids maleic acid is a much stronger acid than fumaric, even though they are simply the cis and trans isomers of butenedioic acid:. Trans-2-butenedioic acid fumaric acid is used as a food additive and acid regulator it is used in the production of polyester resins and polyhydric alcohols.
This regulation establishes an exemption from the requirement of a tolerance for residues of 2-butenedioic acid (2z)-, monobutyl ester, polymer with methoxyethene, sodium salt, minimum number average molecular weight of (in amu) 18,200 (cas reg no 205193-99-3) when used as an inert ingredient. Fumaric acid is a carboxylic acid carboxylic acids donate hydrogen ions if a base is present to accept them 2-butenedioic acid (e)-2-butenedioic acid, (e)-. For this compound, wtt contains critically evaluated recommendations for: (please note that if more than 50 points are used for regression, only the 50 most-constraining points are reported). Fumaric acid is a colorless crystalline solid the primary hazard is the threat to the environment immediate steps should be taken to limit spread to the environment.

Sigma-aldrich offers a number of maleic acid products view information & documentation regarding maleic acid, including cas, msds & more. Maleic acid (also called cis-butenedioic acid), a white crystals easily soluble in water, acetone, and alcohol, is an unsaturated organic dibasic acid which.
In systematic iupac nomenclature, the carboxylic acid's name is derived from the corresponding parent alkane fumaric acid (trans-butenedioic acid). Fumaric acid, or trans-butenedioic acid, the geometrical isomer of maleic acid, occurs in fumitory (fumaria officinalis), in various fungi, and in iceland mosslike maleic acid, it is used in polyesters, and since it is nontoxic, unlike maleic acid, it is used as an acidulant. 2-butenedioic acid (z)- 2-butenedioic acid (2z)- cis-butenedioic acid most important symptoms and effects, both acute and delayed.
Maleic acid is a colorless crystalline solid having a faint odor it is combustible though it may take some effort to ignite it is soluble in water. Experiment a: cis-trans conversion of butenedioic acid pre-lab assignment 1 maleic acid is the cis version and fumaric acis is the trans version of butenedioic acid.
