Fumaric acid boiling point values and conditions
Reported boiling point ranges
Scientists have found different boiling points for fumaric acid. Some books say it can be as high as 522°C. Others say it is 137°C or 165°C. These numbers can make people confused. The reason is that scientists use different ways to measure boiling point. They also use different conditions. Sometimes, the pressure is very low when they measure it. This is not the same as normal room pressure. The boiling point can also change if the sample is not pure.
| Reported Boiling Point (°C) | Pressure (mm Hg) | Source/Condition |
|---|---|---|
| 522 | Not specified | Some chemical handbooks |
| 156 | 1.7 | Laboratory measurement |
| 137 | Not specified | Literature reference |
| 165 | Not specified | Sublimation temperature |
Effects of pressure and purity
Pressure is important for boiling point. If the pressure is lower, fumaric acid boils at a cooler temperature. If the pressure is higher, it boils at a hotter temperature. Purity is also important. If there are other chemicals in the sample, the boiling point can change. Labs use very pure fumaric acid to get good results. NORBIDAR gives very pure fumaric acid. This helps people get the right data for their work.
Tip: Always look at the pressure and purity when you compare boiling points. This helps you not make mistakes in science or factories.
Sublimation and measurement challenges
Fumaric acid does not always act like other liquids. Sometimes, it goes from solid to gas without becoming a liquid. This is called sublimation. Sublimation makes it hard to find the real boiling point. Many scientists see fumaric acid sublimate at 165°C. But the boiling point is about 137°C. This means it can skip the liquid step in some cases.
- Fumaric acid turns to gas at 165°C.
- It can become gas before reaching its boiling point of 137°C.
These facts show why boiling points for fumaric acid are not always the same. Scientists need special tools and ways to measure it right. Knowing these problems helps people use fumaric acid safely in food, factories, and science.

Common misconceptions about fumaric acid properties
Boiling point vs. melting point
Some people mix up boiling point and melting point for fumaric acid. These are two different things. The melting point is when a solid becomes a liquid. The boiling point is when a liquid becomes a gas. Fumaric acid has a higher melting point than other acids like maleic acid. Look at the table below to see how fumaric acid and maleic acid are different:
| Acid | Melting Point (°C) | Molecular Shape | Crystal Packing | Stability |
|---|---|---|---|---|
| Fumaric Acid | 287 | Trans | Tightly packed | Higher |
| Maleic Acid | 130-139 | Cis | Loosely packed | Lower |
Fumaric acid melts at 287°C. This is because its crystals are packed tightly. Maleic acid has a different shape and melts at a lower temperature. The boiling point for fumaric acid is hard to find. It often turns into gas before it boils.
Tip: Always check if the number is for melting point or boiling point. Mixing them up can cause problems in labs or factories.
Why boiling point is less referenced
Most books and product sheets show the melting point for fumaric acid. They do not show the boiling point much. This is because fumaric acid usually skips being a liquid. It goes from solid to gas. Scientists call this sublimation. Because of this, the boiling point is hard to see or use. People use the melting point for heating, mixing, or storing fumaric acid.
Related physical properties
Fumaric acid has other important features. It is a white powder and does not smell. It dissolves slowly in water but faster in alcohol.
