What are the physical properties of 2- (4-Methylphenyl) Propanoic Acid (MPPA)?
2-% 284 - Methylphenyl%29Propanoic Acid% 28MPPA% 29, that is, 2- (4-methylphenyl) propionic acid. This substance has many physical properties.
Looking at its properties, under room temperature and pressure, it is mostly white to white crystalline powder. Its appearance is pure and uniform, and the texture is delicate, just like snow and jade chips, giving people a delicate feeling.
As for the melting point, it is about 75-79 ° C. When the temperature gradually rises, this substance gradually melts from solid to liquid, just like ice disappearing under the warm sun, quietly changing its shape. The characteristics of the melting point are of great significance for the identification, purification and control of related chemical reactions.
In terms of solubility, it is slightly soluble in water, which is due to the characteristics of its molecular structure. There are hydrogen bonds between water molecules, while the molecular structure of 2- (4-methylphenyl) propionic acid interacts weakly with water, so it is difficult to dissolve in water. However, it is soluble in organic solvents such as ethanol and ether. Because the molecules of organic solvents and 2- (4-methylphenyl) propionic acid molecules can form similar interactions, such as van der Waals force, they are soluble and friendly. Just like the fusion of fish and water, organic solvents become a good place for them.
Its density is also an important physical property.

In addition, the stability of 2- (4-methylphenyl) propionic acid is good. Under normal conditions, it is not easy to decompose, oxidize and other chemical reactions, and can maintain its own chemical structure and physical form for a long time. It is like a calm person who is unflappable and maintains its own characteristics in various environments, providing it with convenience and reliability in practical applications.
2- (4-Methylphenyl) Propanoic Acid (MPPA)
2-%284-Methylphenyl%29Propanoic Acid (MPPA) is 2- (4-methylphenyl) propionic acid. There are many methods for synthesis, which are described in detail below.
First, 4-methylstyrene is used as the starting material. First, 4-methylstyrene is hydroformylated with carbon monoxide and hydrogen under suitable temperature and pressure conditions under suitable catalysts, such as rhodium or cobalt-containing complex catalysts, to obtain 2- (4-methylphenyl) propionic acid. Subsequently, the obtained propionic aldehyde is further oxidized in an alkaline medium with suitable oxidants, such as manganese dioxide or oxygen, to obtain 2- (4-methylphenyl) propionic acid.
Second, starting from 4-methylbenzyl halide. Let 4-methylbenzyl halide and diethyl malonate undergo nucleophilic substitution reaction under the catalysis of alkaline reagents such as sodium alcohol to generate the corresponding diethyl malonate derivative. After that, the derivative can be converted into 2 - (4-methylphenyl) propionic acid after hydrolysis and decarboxylation.
Third, 4-methylacetophenone is used as raw material. First, 4-methylacetophenone is condensed with formaldehyde under alkaline conditions to generate β-hydroxy ketone intermediates. This intermediate is then dehydrated to form α, β-unsaturated ketones. Finally, the catalytic hydrogenation of unsaturated ketones is carried out, accompanied by the oxidation of carbonyl groups, to obtain the target product 2- (4-methylphenyl) propionic acid.
These synthesis methods have their own advantages and disadvantages. Considering the cost of raw materials, reaction conditions, and purity of the product, careful choices are required to achieve the purpose of efficient synthesis of 2- (4-methylphenyl) propionic acid.
What is the price trend of 2- (4-Methylphenyl) Propanoic Acid (MPPA) in the market?
In today's world, business conditions change, and it is not easy to know the market price trend of 2 - (4 - methylphenyl) propionic acid (MPPA). However, from the context of past business conditions, you can get a glimpse of its end.
In the past, the price of chemical raw materials was often tied to the balance of supply and demand, but also related to changes in the current situation and technology. MPPA, if the supply exceeds demand, the price will fall. Because producers compete for sales and want to sell their goods quickly, they have to reduce profits in order to sell. On the contrary, if the demand exceeds the supply, the price will rise. If there are many people in need downstream and the supply is in short supply, the price will rise.
Also, changes in the current situation also have a great impact on its price. The regulation of the government, whether strict or lenient, is related to the cost of the producer. If taxes increase and regulations are strict, the cost of the producer will increase, and the price will also rise accordingly. On the contrary, if the benefits are frequent, the cost will be reduced, and the price may also drop. The international situation is also the key. If trade disputes start, tariffs will be increased sharply, or raw materials will be difficult to enter, and the price will be low.
The innovation of the process is also the cause of price fluctuations. If there is a new technology, which can greatly increase the yield and reduce the cost, the market will gradually increase the number of goods, and the price will fall. However, if no new technology comes out, the producer will be conservative, the cost will remain high, and the price will be difficult to drop.
To sum up, the price of MPPA is influenced by factors such as supply and demand, current situation, and technology in the market. To understand its trend, it is necessary to carefully observe the changes in these numbers in order to obtain a rough estimate. However, the market is unpredictable, and it is difficult to fully understand its details.
