When storing and transporting 2-% cyanogen-4- (triethylmethyl) pyridine, it is necessary to pay attention to many key matters.
First, because of its certain toxicity, it is related to personal safety. When storing, it is necessary to choose a well-ventilated and dry warehouse. It is strictly forbidden to mix with food, beverages, feed and other items to prevent accidental contact and ingestion. When transporting, transporters also need to be equipped with corresponding protective equipment, such as gas masks, protective clothing, etc., and transportation vehicles should also ensure sealing to prevent leakage.
Second, this substance is potentially harmful to the environment or exists. During storage, there should be perfect anti-leakage measures, such as laying anti-penetration materials on the floor of the warehouse and setting up cofferdams around it. Once leakage occurs, the pollution range can be effectively controlled. During transportation, if you accidentally leak, you need to start an emergency plan immediately, properly collect and deal with the leakage, and avoid flowing into the soil, water and other environments.
Third, temperature and humidity have a great impact on its stability. When storing, the warehouse temperature should be controlled within a specific range. Generally speaking, it is better to 5 ° C to 30 ° C, and the humidity should be kept at 40% to 70%. It is necessary to regularly monitor and regulate the temperature and humidity of the warehouse, and configure a temperature and humidity meter and corresponding control equipment. When transporting, you should also pay attention to avoid the impact of severe changes in external temperature and humidity. For example, when transporting during high temperatures in summer, vehicles should have good insulation measures. When it is low in winter, it is necessary to prevent packaging damage due to freezing.
Fourth, the packaging must be solid and reliable. When storing, the packaging materials used must be able to effectively block air, moisture, etc., and have certain compression and drop resistance properties to prevent danger caused by package damage. During transportation, the packaging should be carefully checked to ensure that the packaging will not be loose or broken during long-distance transportation and handling. If glass bottle packaging is used, it needs to be reinforced with wooden boxes, etc., and the interior is filled with cushioning materials.

Wen Jun inquired about the market price range of 2-chloro-4- (triethylmethyl) pyridine. This compound is widely used in various industrial fields today, so its price is also influenced by many factors.
As far as its market circulation is concerned, if it is of ordinary purity and suitable for general industrial use, its price is roughly between X yuan and Y yuan per kilogram. Products of this purity grade are widely used in common chemical synthesis processes and can meet the needs of most general production.
However, if the purity requirements are strict and reach a high purity level, it is mostly used in high-precision fields such as pharmaceutical research and development and fine chemicals, and its price will rise sharply. Such high-purity 2-chloro-4- (triethylmethyl) pyridine, the price per kilogram may be above Z yuan. Because the preparation of high-purity products requires more complicated processes and stricter quality control, the cost will also increase sharply, resulting in high prices.
In addition, the market supply and demand situation is also a key factor affecting its price. If the market demand is strong and the supply is relatively short, the price will rise; conversely, if the market supply is abundant and the demand is weak, the price may decline.
The fluctuation of raw material prices, the innovation of production technology, and the change of policies and regulations will all affect the market price of 2-chloro-4- (triethylmethyl) pyridine. Therefore, its price is difficult to say in a word, and it needs to be determined comprehensively according to specific time and space situations, product specifications and many other factors.
