What are the physical properties of malonic acid?

Malonic acid, also known as malonic acid, is an important organic compound. Its physical properties are unique, and let me tell you one by one.
Malonic acid at room temperature and pressure appears as a white crystalline state, like fine snow powder, with a pure texture. Its crystal structure is regular and orderly, which makes malonic acid stable to a certain extent.
Looking at its melting point, it is about 135.6 ° C. When the temperature rises to this point, malonic acid will gradually melt from solid to liquid like ice and snow in the warm sun, starting a journey of other forms. The boiling point is 386.8 ° C.

What are the chemical properties of malonic acid?

Malonic acid (Malonic Acid) is an organic compound with the molecular formula\ (C_ {3} H_ {4} O_ {4}\) and the simple structural formula\ (HOOC - CH_ {2} -COOH\). This substance has many chemical properties and is used in many fields.
Malonic acid is acidic because its molecule contains two carboxyl groups\ (- COOH) \), which can ionize hydrogen ions in water\ ((H ^{+})\) ， so it is acidic. Its acidity is stronger than acetic acid, and partial ionization can occur in water, such as:\ (HOOC - CH_ {2} -COOH\ rightleftharpoons HOOC - CH_ {2} -COO ^ {-} + H ^{+}\) 。 Because of its acidity, malonic acid can neutralize with bases. Taking sodium hydroxide as an example, the reaction is as follows:\ (HOOC - CH_ {2} -COOH + 2NaOH\ rightarrow NaOOC - CH_ {2} -COONa + 2H_ {2} O\) to generate the corresponding malonate and water.
Malonic acid also has the properties of esterification reaction. Under the condition of concentrated sulfuric acid as catalyst and heating, malonic acid can be esterified with alcohol. For example, when reacting with ethanol, the chemical equation is:\ (HOOC - CH_ {2} -COOH + 2C_ {2} H_ {5} OH\ xrightarrow [{\ Delta}] {concentrated sulfuric acid} C_ {2} H_ {5} OOC - CH_ {2} - COOC_ {2} H_ {5} + 2H_ {2} O\) to form diethyl malonate and water. This esterification reaction is quite important in the field of organic synthesis, and diethyl malonate is an important intermediate in organic synthesis.
When heated, malonic acid is easily decarboxylated. When heated to a certain temperature, a carboxyl group in its molecule will be removed in the form of carbon dioxide\ (CO_ {2}) \). The reaction is as follows:\ (HOOC - CH_ {2} -COOH\ xrightarrow {\ Delta} CH_ {3} COOH + CO_ {2}\ uparrow\) to form acetic acid and carbon dioxide. This decarboxylation reaction is of great significance in the study of organic chemistry mechanisms and some organic synthesis pathways.
Malonic acid can also participate in substitution reactions. Because the hydrogen atom on the\ (- CH_ {2} -\) in the molecule can be replaced by other atoms or atomic groups under specific conditions. For example, under appropriate catalyst and reaction conditions, halogen atoms can replace hydrogen atoms on\ (- CH_ {2} -\) to generate halogenated malonic acid derivatives, which can be used in organic synthesis to introduce specific functional groups and expand the structure and properties of organic compounds.

What are the methods for preparing malonic acid?

Malonic acid (Malonic Acid), there are several ways to prepare it. First, cyanoacetic acid is used as raw material and obtained by hydrolysis. First, take an appropriate amount of cyanoacetic acid, put it in the reaction kettle, add an appropriate amount of water and catalyst, and slowly heat it up. Under suitable temperature and pressure, the cyano group is hydrolyzed into a carboxyl group, which is a key step. The cyanoacetic acid of cyanoacetic acid meets water and the catalyst, and after chemical reaction, it is gradually converted into the carboxyl group of malonic acid. After the reaction is completed, the pure malonic acid can be obtained by separation and purification.
Second, chloroacetic acid is used as the starting material. First, chloroacetic acid is reacted with sodium carbonate to form sodium chloroacetate. This reaction requires precise control of the proportion of materials and the conditions of the reaction, and attention should be paid to temperature and pH. Chloroacetic acid and sodium carbonate are mixed in a certain proportion, and the reaction is stirred at a specific temperature to obtain sodium chloroacetate. Then, sodium chloroacetate is reacted with sodium cyanide to form sodium cyanoacetate. This step of the reaction needs to be carried out in a safe environment, because sodium cyanide is highly toxic. Finally, sodium cyanoacetate is hydrolyzed to obtain malonic acid. When hydrolyzing, factors such as temperature and catalyst should also be paid attention to to so that the reaction can proceed smoothly and the purity of the product can be guaranteed.
Furthermore, diethyl malonate is also used as a raw material for preparation. Diethyl malonate can be converted into malonic acid through hydrolysis and decarboxylation. Diethyl malonate is placed in a suitable reaction system, hydrolyzed into monoethyl malonate is added with a hydrolyzer, and then decarboxylated to obtain malonic acid. In this process, the conditions of hydrolysis and decarboxylation are very important, and the temperature and reaction time are all related to the yield and purity of the product. Different preparation methods have their own advantages and disadvantages, and should be selected according to the actual demand, availability of raw materials, cost and other factors.

What are the precautions for malonic acid in storage and transportation?

Malonic acid is also a chemical substance. During storage and transportation, many matters must be paid attention to.
When storing, the first environment is heavy. It should be placed in a cool, dry and well-ventilated place. Because of its easy deliquescence, if it is in a humid place, it may cause quality changes. And the temperature should also be suitable, too high temperature, or the instability of its chemical properties, which will affect its effectiveness.
Furthermore, the choice of container is crucial. Corrosion-resistant devices must be used to avoid chemical reactions with the container and damage its essence. Seal must be tight to prevent contact with air, causing it to oxidize or absorb moisture.
As for transportation, stability comes first. Pack light and unload lightly. Do not subject it to violent vibration and collision, otherwise the package may be damaged and malonic acid will spill out.
The transportation environment should not be ignored, and it should be kept dry to avoid water and wet gas. If it is transported for a long time, it is necessary to check regularly during the transportation to see if the packaging is damaged and the quality is not changed.
In addition, the transporter must be familiar with the nature and precautions of malonic acid, and know the countermeasures in the event of an accident. In this way, when storing and transporting malonic acid, its quality can be guaranteed and its safety can be guaranteed.
