The physical properties of 2-% methyl-3-methoxy phenyl are as follows:
Its external color is usually a liquid color to a light color, and it usually exists. Smell it, there is a special aromatic smell. This smell is slightly irritating, but it is not strong and pungent.
Its boiling temperature is generally specific to the specific phase. Due to its molecular force characteristics, it requires a certain energy to be reduced by the liquid. It is determined that its boiling temperature is around [X] ° C. This degree allows the molecule to obtain sufficient energy to overcome the molecular attractive force and escape from the liquid phase.
Melting is also important. Due to the way the molecules are arranged and interact, in the process of reduction, the phase will be generated at a certain degree, and the liquid will solidify. Its melting temperature is at [X] ° C, and the molecules are weak, and they are arranged in an orderly manner to form a solid lattice.
In terms of solubility, this compound exhibits good solubility in multi-solubility. For example, it is often soluble in ethanol, ether, etc. This is because its molecules are insoluble. Molecules can form interactions such as van der force, and so on to promote their mixing. In water, the solubility is poor because there are few water-based molecules, and water molecules can form effective interactions, so it is not soluble in water.
Density is also a physical index. Its density has a specific ratio with respect to water, which is [X] g/cm ³, indicating that under the same conditions, there is a difference in the amount of water. This property is significant in the analysis of multi-chemical operations, and can help in the separation, preparation, and other processes.
Therefore, the general physical properties of 2-% methyl-3-methoxyphenyl are determined by its molecules, and are of great importance in the study of chemical industry, chemical industry, and other fields. It provides a basis for its synthesis, separation, extraction, and performance investigation.

To prepare 2-methyl-3-methoxybenzaldehyde, there are three methods.
First, 2-methylphenol is used as the starting material. First, 2-methylphenol and dimethyl sulfate are methylated in an alkaline environment to obtain 2-methylanisole. Then aluminum trichloride is used as the catalyst to make 2-methylanisole and chloroform through Fu-gram acylation reaction to obtain 2-methyl-3-methoxybenzaldehyde. In this way, the methylation reaction is mild in one step, but the Fu-gram acylation reaction needs to be in an anhydrous environment, and aluminum trichloride is easy to decompose in contact with water, which requires quite strict operation.
Second, it is based on m-cresol. M-cresol is first methylated to obtain 3-methoxyphenol. Then 3-methoxyphenol reacts with methylating agents such as iodomethane to obtain 2-methyl-3-methoxyphenol. Finally, 2-methyl-3-methoxyphenol is oxidized to 2-methyl-3-methoxybenzaldehyde with a suitable oxidizing agent, such as a mixture of manganese dioxide and sulfuric acid. In this way, the reaction selectivity of each step is acceptable, but the choice of oxidizing agent and the control of reaction conditions depend on the purity and yield of the product.
Third, start with o-toluic acid. O-toluic acid is first esterified to form methyl o-toluate. It is reduced to o-toluol with a reducing agent such as sodium borohydride, and then halogenated to obtain o-methylbenzyl halide. Then the o-methylbenzyl halide is reacted with a methoxylating agent to introduce a methoxy group to obtain 2-methyl-3-methoxybenzyl halide. Finally, a mild oxidizing agent, such as the combination of DMSO and oxalyl chloride (Sven oxidation), is oxidized to 2-methyl-3-methoxybenzaldehyde. This step is a little more complicated, but the reaction conditions of each step are relatively mild, and the requirements for equipment are slightly lower.
These three production methods have their own advantages and disadvantages, and the optimal method should be selected according to actual conditions, such as the availability of raw materials, the conditions of equipment, and the consideration of cost.

2-% methyl-3-methoxybenzene is based on the following things to pay attention to during storage and transportation:
First, heat avoidance and fire protection. This substance is more sensitive to heat, and high temperature can easily cause it to decompose or other chemical reactions, and even cause danger. And it has a certain flammability. In case of open flame, hot topic or strong oxidant, there is a risk of combustion and explosion. Therefore, the storage place must be kept cool and ventilated, away from fire, heat sources and oxidants.
Second, moisture-proof. Its chemical properties may be affected by moisture, and moisture may intervene or cause hydrolysis and other reactions, thus changing its chemical structure and properties. When storing, it should be placed in a dry place, and the packaging must be tight. Desiccant can be considered to prevent moisture and deterioration.
Third, proper packaging. During transportation and storage, the packaging materials must be strong and well sealed to resist external impact and prevent leakage. Suitable plastic drums, iron drums, etc. can be selected, and lined with plastic bags to ensure that the packaging is not damaged.
Fourth, isolated storage. Do not mix with acids, alkalis, oxidants and other substances that are contrary to the nature, to prevent violent chemical reactions. Because of its contact with acids and alkalis, it may cause reactions such as neutralization and decomposition; encounter with oxidants, or dangerous reactions such as oxidation occur.
Fifth, the logo is clear. The name of the substance, characteristics, hazard warnings and other information should be marked on the prominent position of the package to facilitate identification and handling, so that the operator can clearly understand the danger and corresponding protective measures.
Sixth, follow the regulations. Whether it is storage or transportation, it must strictly follow the relevant laws and regulations and standards of the state and local areas to ensure legal compliance, safety and order of operation.

2-% methyl-3-methoxybenzaldehyde, this substance has its impact on the environment and human health.
At the environmental end, if it escapes into the atmosphere, it can participate in photochemical reactions and affect atmospheric quality. Because it is volatile, or interacts with other chemicals in the atmosphere to generate secondary pollutants, such as ozone, resulting in deterioration of air quality, which may have potential effects on regional and even global climate. If it flows into water bodies, due to its chemical properties, it may be difficult to degrade, or it may accumulate in aquatic organisms, pass along the food chain, disturb the balance of aquatic ecosystems, affect the survival and reproduction of aquatic organisms, and pose a threat to aquatic biodiversity.
As for human health, short-term exposure may irritate the eyes, skin and respiratory tract. If the skin touches it, it may cause allergies, redness, swelling, itching and other symptoms; if inhaled its volatile gas, it can cause cough, asthma, dyspnea, and damage to respiratory mucosa. Long-term exposure, the risk is even greater. It may damage the human nervous system, causing headaches, dizziness, fatigue, memory loss and other neurological disorders. It may also affect the human endocrine system, interfere with the normal secretion and regulation of hormones, and cause reproductive and developmental problems. And this substance may be potentially carcinogenic, and long-term exposure may increase the risk of cancer. Therefore, the use and emission of 2-methyl-3-methoxybenzaldehyde should be handled with caution and strengthened to reduce its harm to the environment and human health.
