1. Maleic anhydride is hydrated. This produces maleic acid.
2. Maleic acid is isomerised in the presence of a catalyst.
3. Fumaric acid is produced.
Easy as that! (Except the temperature and pressure have to be kept controlled throughout)

What type of isomers is shown by maleic acid and fumaric acid?
Maleic acid and fumaric acid are cis-trans isomers of each other.
What is an aspartase?
An aspartase is an enzyme which catalyzes the deamination of aspartic acid to fumaric acid and ammonia.
What is the method of preparation aluminum stearate?
It is prepared by the reaction of Aluminium Hydroxide and molten stearic acid at 60oC. Give stay time at same temperature and then spin off water from it,dry, micronize and pack.
What acid is used by Industrial chemist to produce fertilizers and Explosive?
Sulfuric acid.
What type of preparation is used in acetic acid dilution?
Simply mix water and acetic acid to the desired concentration.
What type of isomers is shown by maleic acid and fumaric acid?
Maleic acid and fumaric acid are cis-trans isomers of each other.
Why is fumaric acid a stable acid?
Fumaric acid being the trans isomer will have the least stearic hindrance as the carboxylic acid groups will be on the different sides of the double bonds-hence causing the least electronic repulsion. Fumaric acid will be more stable as compared to maleic acid.
What are some sources of error in the preparation ans isolation of fumaric acid?
I don't know dipsht, why don't you get off your lazy as and ask your teacher dammt
What is the industrial preparation method of copper sulphate?
The scrape orwasted copper pieces are boiled in sulphuric acid in open air then mixture is worked up with water.
What has the author John Jacob Kessler written?
John Jacob Kessler has written: 'The nitrile of fumaric acid' -- subject(s): Fumaric acid, Nitriles
Is formation of malic acid from fumaric acid found in the mitochondria?
yes
Which is the best method of estimate acetic acid in pharmaceutical and commercial preparation?
titration method
What is the acid present in carrot?
Malic Acid, Citric acid, Isocitric Acid, Succinic Acid and Fumaric Acid.
What happens if fumaric acid is mixed with ammonia?
just tried it. a dash of reagent grade fumaric acid was covered in janator strength non detergent ammonia. no observable reaction....
Why is fumaric acid dried in the oven?
Fumaric acid is dried in an oven at a relatively low heat - below 130 degrees centigrade - to evaporate any water that might be left over from formation. If it is heated above 130 degrees, the fumaric acid starts to decompose and form maleic acid, maleic anhydride, carbon monoxide and carbon dioxide. The acid may be dried for a number of reasons. Commercially because water has weight but no value, it is cheaper to transport completely dry fumaric acid. Water may also cause unwanted reactions with other chemicals which the fumaric acid is eventually added to. Removing the water then removes the reactions.
What is an aspartase?
An aspartase is an enzyme which catalyzes the deamination of aspartic acid to fumaric acid and ammonia.
What is the chemical formula for trans-butenedioic acid?
trans-butenedioic acid,C4H4O4 also called fumaric acid
