What are the preparation methods of Ethyl 4-Methylcinnamate?
There are several common methods for preparing ethyl 4-methyl cinnamate. One is to use 4-methyl cinnamic acid and ethanol as raw materials, and perform esterification reaction under acid catalysis. Among them, concentrated sulfuric acid is often selected as a catalyst, because of its high catalytic activity, it can promote the reaction to the direction of ester formation. However, concentrated sulfuric acid is highly corrosive, has certain damage to equipment, and subsequent treatment is complicated. The reaction is roughly as follows: put 4-methyl cinnamic acid and ethanol in a reaction vessel in a certain proportion, add an appropriate amount of concentrated sulfuric acid, heat and stir, and control the temperature to make the reaction proceed smoothly. After the reaction is completed, the pure ethyl 4-methyl cinnamate is obtained through neutralization, washing, distillation and other steps.
Second, the acid chloride method can be used. First, 4-methyl cinnamic acid is reacted with sulfoxide chloride to obtain 4-methyl cinnamyl chloride. This reaction is relatively mild and the yield is quite high. Then, 4-methyl cinnamyl chloride reacts with ethanol in the presence of a base to form 4-methyl cinnamic acid ethyl ester. In this process, the base can neutralize the hydrogen chloride generated by the reaction, making the reaction more complete. During the specific operation, 4-methyl cinnamic acid is mixed with sulfoxide chloride and heated properly to make the reaction sufficient to obtain 4-methyl cinnamyl chloride. After that, it is slowly dropped into a solution containing ethanol and base, stirred and reacted, and then separated and purified to obtain the target product.
Third, the transesterification method can also be used as a preparation method. Methyl 4-methyl cinnamate and ethanol are used as raw materials, and the transesterification reaction is carried out under the action of a catalyst. This catalyst is mostly metal alkoxides. During the reaction process, conditions such as temperature, proportion of raw materials and reaction time need to be strictly controlled to make the reaction proceed smoothly. Ethyl 4-methyl cinnamate can be separated by distillation and other means. This method has relatively mild conditions and a wide range of raw materials, which has certain application value.
What are the precautions for Ethyl 4-Methylcinnamate in storage and transportation?
Ethyl-4-methyl cinnamate is also an organic compound. During storage and transportation, it is necessary to pay attention to many matters.
First storage environment. This substance should be placed in a cool, dry and well-ventilated place. The cover is sensitive to heat, and high temperature can easily cause its properties to change. Therefore, it should not be close to fire or heat sources to avoid thermal decomposition or the risk of other chemical reactions. If stored in a humid place, it may be deteriorated by moisture, which will affect its quality.
Second words packaging. Packaging materials with excellent sealing performance should be used to prevent excessive contact with air. Oxygen in the air may oxidize it, which in turn affects its chemical properties and quality. The packaging must be sturdy to prevent damage and leakage during transportation.
In addition to the transportation process. Make sure it is stable during transportation to avoid violent vibration and collision, otherwise it may cause damage to the packaging and cause danger. At the same time, the means of transportation must also be kept dry and clean, and should not be mixed with other substances that are prone to reactions. If it coexists with oxidizing, acidic or alkaline substances, it is very likely to trigger chemical reactions and endanger transportation safety.
In addition, storage and transportation sites should be equipped with corresponding fire and leakage emergency treatment equipment. Once a leak occurs, it can be properly handled in a timely manner to prevent environmental pollution and ensure personnel safety.
In short, the storage and transportation of ethyl-4-methyl cinnamate should be carried out with care and follow relevant norms and requirements to ensure its quality and safety.
