What are the physical properties of Methyl 4-Methylcinnamate?
The physical properties of methyl-4-methyl cinnamate ester are as follows:
This substance is mostly colorless to light yellow liquid at room temperature, and it is clear and translucent, like morning dew shining on the sun, pure and impure. Its smell is unique, like a light and elegant floral fragrance, leisurely lingering, not pungent but refreshing, like the fragrance of the spring breeze.
On its melting and boiling point, the melting point is within a specific range, just like ice melting in the warm sun, and it needs a suitable temperature to change its form; the boiling point is relatively high. If you want to turn water into steam, you need to reach a certain heat. The same is true for this substance, which needs a higher temperature to boil.
In terms of solubility, in organic solvents, it is like a fish getting water, and it is very easy to dissolve. Such as ethanol, ether and other organic solvents, mixed with it, it is like water and emulsion, and can form a uniform mixed system. However, in water, its solubility is poor, just like oil floating in water, the two are difficult to fuse, and can only coexist in a layered state.
Its density is slightly higher than that of water, and it is poured into the water, like a stone sinking in the abyss, slowly settling at the bottom. And this substance has a certain refractive property. When the light shines, it can be seen that its refraction is wonderful, just like the glass reflects the sun, and it is colorful.
What are the chemical properties of Methyl 4-Methylcinnamate?
Methyl-4-methyl cinnamate is an organic compound with unique chemical properties. Its appearance is often colorless to light yellow liquid, fragrant and rich, and it is widely used in the fields of fragrance and medicine.

What is the production method of Methyl 4-Methylcinnamate?
The method of preparing methyl 4-methyl cinnamic acid ester is a multi-step chemical synthesis. The common one is to use 4-methyl cinnamic acid and methanol as raw materials and prepare it by esterification reaction.
First take an appropriate amount of 4-methyl cinnamic acid, place it in a clean reaction vessel, and then pour a certain proportion of methanol into it. In order to promote the speed of this esterification reaction, a catalyst is often added, and sulfuric acid and the like are often used. During the reaction, the temperature of the system is heated to rise, generally controlled in a suitable temperature range, such as 60-80 degrees Celsius, so that it can fully react.
During the reaction process, the acid and alcohol are esterified to gradually produce methyl 4-methyl cinnamic acid ester and water. In order to make the reaction complete, water can be removed by azeotropic distillation to push the equilibrium to move in the direction of product formation.
After the reaction is completed, the product needs to be separated and purified. The excess acid is often removed by neutralization reaction, and the organic phase is neutralized with alkali solution. Then by distillation, according to the difference in boiling points of different substances, pure methyl 4-methyl cinnamate is separated and the target product is obtained.
What are the precautions for the storage and transportation of Methyl 4-Methylcinnamate?
When storing and transporting methyl-4-methyl cinnamate, many matters need to be paid attention to.
First storage environment. This substance is extremely sensitive to temperature and humidity, and should be stored in a cool and dry place. If the temperature is too high, it may cause its volatilization to accelerate, and even cause chemical reactions, which will damage its quality; if the humidity is too high, or it will deteriorate due to moisture, the storage place should be kept dry, and the humidity should not exceed [specific suitable humidity]. And it needs to be kept away from fire and heat sources. Because of its flammability, it is easy to cause combustion in case of open flames and hot topics, which will cause disasters.
Furthermore, when transporting, the packaging must be tight. To ensure that there is no leakage caused by vibration or collision during transportation. Suitable packaging materials, such as sturdy containers, should be selected, and the container must be able to withstand certain pressure and temperature changes. During handling, the operation should also be cautious, and light handling should be carried out to avoid package damage caused by brutal handling.
In addition, attention should also be paid to its isolation from other substances. Methyl-4-methyl cinnamate cannot be mixed with oxidants, acids, alkalis, etc. Due to its chemical activity, contact with the above substances can easily trigger chemical reactions or cause danger.
Only by paying strict attention to all matters during storage and transportation can the quality and safety of methyl-4-methyl cinnamate be ensured.
