3% 2C4 -diethylbenzaldehyde oxime benzoate is an organic compound. Its physical properties are as follows:
Viewed at room temperature, this substance is often in the state of white to light yellow crystalline powder, with a fine appearance and a certain luster. Under specific light, its surface shimmer can be seen.
Smell, it has a special organic smell, but this smell is not strong and pungent, but relatively mild, which can be clearly perceived by ordinary people at close range.
When it comes to melting point, after rigorous measurement, its melting point is within a specific temperature range. This property allows it to change from solid to liquid in an orderly manner at a certain precise temperature when heated. This melting point temperature is of great significance for its application in many fields.
In addition to solubility, it exhibits good solubility in organic solvents, such as common ethanol, acetone and other organic solvents, which can effectively disperse and dissolve to form a uniform solution; however, it has extremely poor solubility in water. After encountering water, it is basically insoluble and will remain in water in solid form. This difference in solubility determines its application direction in different media.
Its density is also one of the important physical properties. Through accurate measurement, it can be known that its density is a specific value. Compared with other common organic compounds, this density is unique. In the separation and mixing of substances, this density characteristic will have a significant impact on its behavior.
The physical properties mentioned above are of great significance in many fields such as chemicals and materials. For example, in chemical synthesis, properties such as melting point and solubility play a key role in the precise control of reaction conditions, the separation and purification of products; in material preparation, density and appearance characteristics will affect the final properties and application scenarios of materials.

3,4-Diethylbenzaldehyde oxime is an organic compound with specific chemical properties. Its structure contains a benzene ring, connected with diethyl and aldoxime groups.
This compound is white to light yellow solid or liquid. It is relatively stable at room temperature and pressure. In case of open flame, hot topic, etc., it may cause combustion. Its chemical activity is mainly derived from the aldoxime group, which can participate in many chemical reactions.
From the perspective of reactivity, the nitrogen-oxygen double bond in the aldoxime group has a certain polarity and can participate in nucleophilic addition reactions. For example, it can react with nucleophiles, such as amines and alcohols, to generate new nitrogen-containing or oxygen-containing derivatives, thereby constructing various organic compound structures.
Because of its benzene ring, it has aromatic properties. The benzene ring can undergo substitution reactions, such as halogenation, nitrification, sulfonation, etc. Under appropriate conditions, other functional groups can be introduced on the benzene ring, thereby enriching its chemical properties and uses.
In the field of organic synthesis, 3,4-diethylbenzaldoxime is often used as a key intermediate for the synthesis of complex organic molecules. Due to its unique structure and reactivity, it can build specific skeletons and functional groups for target compounds, providing an effective way for the synthesis of drugs, natural products and functional materials.
In terms of physical properties, melting point, boiling point, etc. depend on intermolecular forces, and factors such as relative molecular weight and molecular structure also affect them. At the same time, the solubility in different solvents varies, generally better in organic solvents such as ethanol, ether, and dichloromethane, but poor in water. This property is important in separation, purification, and reaction medium selection.

There are several methods for the synthesis of 3,4-diethoxybenzaldehyde:
1. ** Using resorcinol as the starting material **: resorcinol and chloroethane are etherified in an alkaline environment and under the action of an appropriate catalyst. Sodium hydroxide can be used as the base. The reaction needs to be carried out in an organic solvent at a suitable temperature and pressure to generate 3,4-diethoxyphenol. Subsequently, 3,4-diethoxyphenol is reacted with a suitable formylation reagent, such as Vilsmeier-Haack reagent composed of phosphorus oxychloride and N, N-dimethylformamide (DMF), after a specific reaction process, 3,4-diethoxybenzaldehyde can be obtained. This process requires precise control of the reaction conditions, including temperature, reagent dosage ratio, etc., to ensure the purity and yield of the product.
2. ** Starting from p-hydroxybenzaldehyde **: p-hydroxybenzaldehyde is first reacted with halogenated ethane under basic conditions and with the help of a phase transfer catalyst to ethoxylate the hydroxyl group. The phase transfer catalyst can accelerate the reaction process and improve the reaction efficiency. After ethoxylation is completed, 3,4-diethoxy benzaldehyde is finally synthesized through a specific functional group conversion reaction, such as through a reasonable oxidation or reduction step to adjust the molecular structure. This route requires proper separation and purification of the intermediate products in each step to prevent the accumulation of impurities from affecting the quality of the final product.
3. ** Using the strategy of direct ethoxylation and formylation of benzene ring **: Benzene is used as the starting material, and ethoxy is directly introduced under specific catalyst and reaction conditions. This step is more difficult and requires the selection of highly active and selective catalysts, such as some transition metal complexes. After the successful introduction of ethoxy group, the formylation reaction is carried out. The formylation process also needs to precisely control the conditions to prevent side reactions such as multi-substitution, and then obtain the target product 3,4-diethoxybenzaldehyde. Although this method is relatively simple, it requires strict reaction conditions and catalysts, and needs to be carefully optimized in actual operation.

3,4-Diethylbenzaldehyde oxime is an organic compound. When using it, many things need to be paid attention to:
First, it is related to safety protection. This compound has certain toxicity and irritation. When operating, be sure to prepare protective equipment, such as protective glasses, which can effectively block it from splashing into the eyes and causing eye damage; wear gloves to prevent skin contact with it, so as not to cause skin allergies or other adverse reactions; wear protective clothing to protect the body in an all-round way. At the same time, the operation should be placed in a well-ventilated place, preferably in a fume hood, so that volatile harmful gases can be discharged in time to avoid inhalation and harm to health.
Second, pay attention to storage conditions. Store it in a cool, dry and ventilated place, away from fire and heat sources. Because of its flammability, it is easy to cause combustion and explosion in case of open flames and hot topics, so the storage environment temperature must be strictly controlled. At the same time, it should be stored separately from oxidants and acids, and must not be mixed to prevent violent chemical reactions and dangerous accidents.
Third, accurately control the dosage used. According to specific experiments or production needs, accurately calculate and use an appropriate amount of 3,4-diethylbenzaldehyde oxime. If the dosage is too large, it will not only cause waste and increase costs, but also cause excessive subsequent reactions, produce many by-products, and affect product quality. If the dosage is too small, the reaction may be incomplete and the desired effect cannot be achieved.
Fourth, be careful with the operation process. During the taking process, the action should be cautious and standardized to prevent the compound from spilling out. If it is accidentally spilled, it should be cleaned up immediately according to the corresponding emergency treatment measures. For example, quickly evacuate unrelated personnel to avoid contact; use suitable adsorption materials to absorb and collect the spill, and then properly dispose of it. Do not discharge it at will to avoid polluting the environment. When conducting related chemical reactions, strictly follow the established reaction conditions and operating procedures, and pay close attention to changes in temperature, pressure and other parameters during the reaction process to prevent accidents.
