The main use of 2-% ethyl-6-methyl-3-furanyl is involved in "Tiangong Kaiwu", which is mostly related to spices, seasoning and other fields.
Looking at the things of all the world's workers, these organic compounds are quite wonderfully used in the preparation of spices. In ancient times, noble people were often good at incense, and the use of spices could make the residence fragrant and rich, and could also show their status. 2-% ethyl-6-methyl-3-furan gene has its unique smell, or is favored by perfumers, and can be added to the fragrance to give a unique charm, or is quiet and elegant, or is rich and mellow, to meet the needs of different users.
As for the seasoning end, it also has considerable advantages. In ancient times, people were good at blending the five flavors to make a delicious dish. 2-% ethyl-6-methyl-3-furyl can be used as a seasoning aid. When cooking, a little addition of this substance may make the aroma of the dish better. Or when used in meat, it can remove its stench and increase its fragrance; or when used in soup, it can make the soup taste more mellow and appealing.
And in the winemaking industry, this compound may also have its function. The brewing of wine, over the years of aging, the formation of aroma is quite complicated. 2-% ethyl-6-methyl-3-furyl or participates in the fermentation process of wine, adding a unique layer to the aroma of wine, making the wine richer in flavor, fresh in fruity aroma, or mellow in grain, making the drinker intoxicated.

To prepare 2-ethyl-6-methyl-3-nitrobenzene, you can follow the following method.
First, start with benzene, and first make benzene and halogenated alkanes (such as chloroethane) under the catalysis of Lewis acid (such as anhydrous aluminum trichloride), Fu-gram alkylation reaction to obtain ethylbenzene. In this reaction, the electron cloud density of benzene is high, and the alkyl positive ion of the halogenated alkane is an electrophilic agent, attacking the benzene ring and forming ethylbenzene. Ethylbenzene reacts with halogenated alkanes (such as chloromethane) under similar conditions to introduce methyl to obtain 2-methylethylbenzene. Subsequently, 2-methylethylbenzene is nitrified by mixed acid (concentrated sulfuric acid and concentrated nitric acid). Due to the fact that both methyl and ethyl are ortho-para-localization groups, the target product 2-ethyl-6-methyl-3-nitrobenzene can be obtained under appropriate conditions by combining the localization effects of the two.
Second, toluene is first used as a raw material and alkylated with halogenated alkanes (such as chloroethane) through Fu-g to obtain 2-ethyltoluene. Then, the nitration reaction is carried out under the action of mixed acids. 2-Ethyl-6-methyl-3-nitrobenzene can also be prepared by controlling the reaction conditions due to the localization effect between methyl and the newly introduced ethyl group.
Thirdly, ethylbenzene is used as the starting material and is alkylated with halomethane through Fu-g to generate 2-methyl-ethylbenzene. Then, through nitration reaction, the conditions are reasonably regulated to promote the introduction of nitro to the target position, thereby synthesizing 2-ethyl-6-methyl-3-nitrobenzene.
All the above synthesis methods need to pay attention to the control of reaction conditions, such as temperature, catalyst dosage, reactant ratio, etc., in order to improve the yield and purity of the target product. In the Fu-gram alkylation reaction, the activity and dosage of Lewis acid have a great influence on the reaction process; in the nitrification reaction, the concentration of mixed acid and the reaction temperature are related to the position and yield of nitro introduction.

2-% ethyl-6-methyl-3-nitrobenzene When storing and transporting this substance, pay attention to many matters.
The first priority is safety, and this compound may be dangerous. Its nitro structure makes it chemically active, and it is very likely to cause combustion or even explosion when heated, hit or exposed to open flames. Therefore, when storing, it must be placed in a cool and ventilated place, away from fire and heat sources, and it should be stored separately from oxidants, reducing agents, acids, bases, etc., and must not be mixed to prevent dangerous reactions from triggering due to interaction.
The transportation process should not be sloppy. It is necessary to use packaging that meets safety standards to ensure that the packaging is complete and sealed to prevent leakage. Transportation vehicles should be equipped with the appropriate variety and quantity of fire fighting equipment and leakage emergency treatment equipment. During driving, avoid exposure to the sun, rain, and high temperature. In the event of a leak, emergency personnel must wear gas masks and protective clothing, and direct contact with the leak is strictly prohibited. In the event of a small leak, it can be mixed with sand, dry lime or soda ash and collected in a dry, clean and covered container. In the event of a large leak, a dike or pit should be built for containment, covered with foam to reduce steam disasters, and then transferred to a tanker or a special collector by pump for recycling or transportation to a waste treatment site for disposal.
In addition, whether it is storage or transportation, it is necessary to strictly follow relevant regulations and operating procedures, make corresponding records, ensure the safety of personnel and the environment, and avoid accidents caused by improper disposal, endangering life, property and the ecological environment.
