All these show that 2-cyanoguanidine is an indispensable chemical raw material in the chemical industry and related industries.
What are the physical properties of Cyanoguanidine?
2-Cyanoguanidine, its physical state is white crystalline powder. Melting point is quite high, about 209-212 ℃. This substance is relatively stable at room temperature and pressure, but flammable in case of open flame and hot topic.
Its solubility is characteristic, slightly soluble in water, slightly soluble in ethanol, but difficult to dissolve in ether and benzene. In acid and alkali solutions, 2-cyanoguanidine will react, decompose, or transform into other substances. Due to the special cyano and guanidine structures, it has certain chemical activity.
In appearance, its white crystalline state can be seen under light, with a fine crystal luster, a relatively fine texture, and a smooth feel. And because of its chemical structure, 2-cyanoguanidine can be used as an intermediate in some chemical reaction systems, participating in a variety of organic synthesis reactions, which is of great significance for the preparation of many chemical products.
What are the precautions for Cyanoguanidine in the production process?
For 2-cyanoguanidine, there are several ends that should be paid attention to in the production process.
First, it is related to the quality of the raw materials. To obtain good 2-cyanoguanidine, the purity and stability of the raw materials are essential. If the raw materials are heterogeneous, the product must be impure, which affects its use. If the raw materials prepared by other means are used, their quality must be carefully checked, and they can be used in accordance with the regulations.
Second, the reaction strip. Temperature, pressure, and time control all react left and right. High temperature, or the reaction is too fast, the product decomposes; low, the reaction is slow, and the yield drops. If a factory makes this product, the temperature is not properly controlled at the beginning, and the yield is only 50%. After the temperature is adjusted to the appropriate, the yield rises to 70%. The same is true for the pressure, and the appropriate pressure promotes the reaction to form 2-cyanoguanidine. The length of time also affects the yield and the product, and the appropriate time must be determined according to the reactivity and equipment conditions.
Third, the matter of safety. 2-Cyanoguanidine production, or something involved in poisoning, combustion or explosion. Operators must strictly abide by regulations and wear protective gear to avoid contact with poison and combustion. Fire protection and ventilation facilities in the factory must be complete and good, in case.
Fourth, the protection of equipment. Reactors, pipelines and other equipment, which are used for a long time or damaged, cause leakage and affect the reaction. It should be inspected regularly, and the wearing parts should be replaced in time to ensure the stable operation of the equipment. If a factory is not inspected on time, the pipeline will leak, causing the leakage of raw materials, which will not only damage the production but also pollute the ring.
In summary, the production of 2-cyanoguanidine should be paid attention to the raw materials, reaction, safety and equipment to ensure smooth production and high quality.
What is the approximate market price of 2-Cyanoguanidine?
2-Cyanoguanidine, the price of the market varies from time to time, and also changes with quality and quantity. Looking at the current markets, its price has not been determined.
In the chemical industry, the price of 2-cyanoguanidine is often determined by its high purity and the state of supply and demand. If the purity is excellent and the supply and demand are in agreement, the price may be moderate; if the supply exceeds the demand, the price may decline; if the demand exceeds the supply, the price will rise.
Also considering the market conditions of the past, when the production of chemical raw materials changes, or when the weather or the government decrees, the price of 2-cyanoguanidine also fluctuates. In the past, the price may have soared due to the scarcity of raw materials; or the price fell like a flow due to abundant production capacity.
Basically speaking, if you want to know the exact price, you need to study the situation of the market in detail, and consult chemical merchants, brokers, or explore the platform of the market to get a near-real price. At present, the price of each unit, low or to tens of currency units, high or hundreds of currency units, it is difficult to determine the exact number. All because of the ever-changing market conditions, it is impossible to be uniform.
What are the requirements for Cyanoguanidine during storage and transportation?
For 2-cyanoguanidine, many requirements need to be paid attention to during storage and transportation.
When storing, the first priority is the dryness of the environment. Because of its certain water absorption, if the environment is humid, it is easy to cause deliquescence and affect the quality. The warehouse should choose a place with high terrain and dryness, and avoid low-lying places that are prone to water accumulation. Furthermore, the temperature should be controlled in a suitable range. Excessive temperature may cause changes in its chemical properties, or cause reactions such as decomposition; although too low temperature has a slight impact on its stability, extreme low temperature may change the physical state of the material, which is unfavorable for use. Usually at room temperature or slightly below room temperature, it is appropriate, roughly between 5 ° C and 30 ° C.
And 2-cyanoguanidine should be placed separately from oxidants, acids and other substances. Due to its chemical structure characteristics, it is easy to oxidize when encountering oxidants, and can deteriorate when encountering acids or chemical reactions.
During transportation, the packaging must be solid and firm. Choose suitable packaging materials, such as plastic bags lined with plastic woven bags, or sealed metal drums, to prevent leakage. When loading and unloading, the operation should be careful, handle it with care, and do not damage the packaging. The transportation vehicle should also be kept clean and dry, and avoid mixing with other contraindicated items. If it rains during transportation, it should be properly shaded to prevent the goods from getting wet. In this way, the quality of 2-cyanoguanidine during storage and transportation is guaranteed.
