To prepare 2-thiophene formaldehyde oxime, there are two methods. One is to use 2-thiophene formaldehyde and hydroxylamine hydrochloride as raw materials. First take an appropriate amount of 2-thiophene formaldehyde and place it in a clean reaction vessel. This vessel should be a round bottom flask, with a stirring device and a condensation reflux device to ensure the stable progress of the reaction. Take another amount of hydroxylamine hydrochloride and dissolve it in an appropriate amount of solvent. This solvent can be selected from ethanol or methanol, because it has good solubility to the reactants and is relatively stable in nature. After the hydroxylamine hydrochloride is completely dissolved, slowly add the solution dropwise into the reaction vessel containing 2-thiophene formaldehyde. The dropwise addition process needs to be slow, and at the same time continue to stir to make the two fully contact the reaction. The reaction temperature can be controlled in a moderate range, about 50-60 degrees Celsius is appropriate, and the temperature can be precisely controlled by heating in a water bath. During the reaction, the change of the reaction system was closely observed, and the color of the solution was visible or changed, and the precipitation was gradually formed. When the reaction is over, the suitable separation means, such as filtration, separate the precipitation, and then wash, dry and other processes, can obtain 2-thiophene formaldehyde oxime crude product, after recrystallization and other refining steps, the product with higher purity can be obtained.
The second method is to use 2-thiophene formonitrile as the starting material. First, 2-thiophene formonitrile is mixed with an appropriate amount of water and acid. The acid can be selected from sulfuric acid or hydrochloric acid, both of which can effectively catalyze the reaction. The reaction is carried out under heating conditions at a temperature of about 80-90 degrees Celsius, which can accelerate the reaction process. During the reaction, 2-thiophenylformonitrile is gradually hydrolyzed to produce 2-thiophenylformaldehyde. After the hydrolysis reaction is completed, the temperature is lowered, the reaction solution is properly treated to remove excess acid and impurities, and then according to the above method of making 2-thiophenylformaldehyde from 2-thiophenylformaldoxime, it reacts with hydroxylamine hydrochloride. After a series of separation and purification operations, the target product 2-thiophenylformaldoxime can also be obtained.

2-Thiophene formaldehyde oxime is also an organic compound. Its storage conditions are of paramount importance, related to the quality and use of this substance.
This substance should be stored in a cool place, away from direct sunlight. Sunlight is hot, which can cause its chemical changes and damage its inherent quality. And it should be placed in a dry place, where moisture can easily lead it to deliquescence, or promote it to react with water, resulting in impurities and damaging its purity.
Furthermore, where it is stored, air should be circulated. If the air is closed, the gas emitted by this substance will accumulate, and in case of fire or heat, it will be dangerous, such as the risk of explosion. < Br >
And when it is kept away from fire and heat sources, its nature may be flammable, and if it is near fire, it will cause a disaster for a moment, endangering storage and the surrounding area. The storage place must also be isolated from oxidizing agents, acids and other substances. The edge of oxidizing agents and acids are both highly reactive, and when they come into contact with them, it is easy to cause severe chemical reactions, or cause damage to people.
And where it is stored, a suitable device must be used. Choose materials that do not react with them, such as glass, specific plastics, etc., to ensure their consistency and prevent leakage.
In general, in order to store 2-thiophene formaldehyde oxime well, it is necessary to meet the requirements of cool, dry, ventilated, fireproof, and isolated, and use adapters to ensure its purity and be safe for later use.
