What is the chemical structure of Diphenyl Guanidine?
Diphenyl Guanidine has a unique chemical structure. This substance is formed by linking diphenyl to guanidine. Looking at its structure, phenyl is a ring-like structure composed of six carbon atoms, and each carbon atom on the ring is connected to a hydrogen atom, showing stable aromatic characteristics. And guanidine, which is strongly basic, is connected by one central carbon atom and three amino groups, one of which is connected to the central carbon in the form of a double bond. This unique structure gives guanidine active chemical properties.
In diphenyl guanidine, two phenyl groups are respectively connected to the central carbon atom of guanidine. Such a structural combination makes diphenylguanidine not only have the aromaticity, stability and hydrophobicity of phenyl group, but also the alkalinity and reactivity of guanidine group. The existence of phenyl group increases the conjugate system of molecules, improves its stability, and affects the electron cloud distribution of molecules; the basic characteristics of guanidine group make it can be used as a proton receiver in chemical reactions, participating in acid-base reactions and many other chemical processes. This structural characteristic makes diphenylguanidine show important application value in rubber additives and other fields. It can be used as an accelerator to accelerate the vulcanization reaction process of rubber and improve the physical and mechanical properties of rubber.
What are the main applications of Diphenyl Guanidine?
Diphenylguanidine has a wide range of uses. In the rubber industry, it is a commonly used vulcanization accelerator. It can increase the vulcanization rate of rubber, reduce the vulcanization time, and improve the physical and mechanical properties of rubber products, making rubber tough and durable. For example, the production of tires, hoses, tapes and other products depends on its help, so that rubber can be rapidly vulcanized and formed, with good wear resistance and aging resistance.
In the field of medicine, it also has its own shadow. It can be used as a pharmaceutical intermediate to provide key raw materials for the synthesis of specific drugs. By chemical synthesis, based on diphenylguanidine, through a series of reactions, drugs with specific pharmacological activities are prepared for the treatment of diseases.
In the paint industry, diphenylguanidine can be used as a catalyst. It can accelerate the drying and curing process of coatings, improve the drying efficiency of coatings, form coatings as soon as possible, and enhance their protection and decorative functions for the coated materials. It is widely used in the preparation of industrial coatings and architectural coatings.
In the field of organic synthesis, diphenylguanidine is often used as an organic base. In many organic reactions, it regulates the pH of the reaction system, promotes the smooth progress of the reaction, and assists the synthesis and transformation of organic compounds. It is an important participant in organic synthesis chemistry.
What are the precautions for Diphenyl Guanidine during use?
For diphenylguanidine, there are several ends to pay attention to when using it.
First, it is related to safety protection. This substance is toxic and irritating to a certain extent. When using it, be sure to wear appropriate protective equipment, such as gloves, goggles and masks, to prevent skin, eyes and respiratory tract from coming into contact with it and causing damage to the body. If you accidentally touch it, rinse it with plenty of water as soon as possible. If the situation is serious, seek medical attention urgently.
Second, the method of storage should not be ignored. It should be placed in a cool, dry and well-ventilated place, away from fire sources, heat sources and oxidants. Because of its active chemical nature, improper storage or deterioration will affect the use effect, and even worse, it may cause safety accidents.
Third, during use, it is crucial to accurately control the dosage. Excessive use of it will not only fail to improve the effect, but may instead cause negative effects, such as in the field of rubber processing, improper dosage or affect the performance of rubber products. It must be operated in strict accordance with regulations and accurately measured according to specific application scenarios and process requirements.
Fourth, pay attention to its compatibility. Before mixing with other chemical substances, it is necessary to check their chemical properties in detail to ensure that there is no adverse reaction with each other. Mixing or chemical reactions of different substances can damage the stability of the system and even produce harmful products.
Fifth, properly dispose of the residue and waste after use. It should not be discarded at will, and should be treated harmlessly in accordance with relevant environmental regulations to avoid polluting the environment.
What is the production process of Diphenyl Guanidine?
The production process of diphenylguanidine has been in place in ancient times, and its method is exquisite, which is described by you today.
First of all, the choice of raw materials is crucial. It is necessary to prepare various raw materials such as aniline, sodium cyanide, carbon disulfide, etc. Aniline is pure, colorless and transparent, and has a special smell. It is the foundation for making diphenylguanidine. Although sodium cyanide is highly toxic, it is indispensable in the process and takes its chemical activity. Carbon disulfide is volatile and is also a key material.
When preparing, aniline and carbon disulfide are first mixed in a specific container, and moderate temperature and pressure are applied. At this time, the two chemically react to form an intermediate product. In this process, the temperature control is as good as being measured, and it cannot be slightly worse. If the temperature is high, the reaction will be too fast, and impurities will be easily produced; if the temperature is low, the reaction will be slow and time-consuming.
Then, add sodium cyanide to make it react with the intermediate product. This step needs to be handled with caution. Sodium cyanide is very toxic and must be well protected. When the reaction continues, observe its changes. When the reaction reaches the right moment, the crude two-phenylguanidine is obtained.
The crude product still needs to be refined. With an appropriate solvent, the crude product is dissolved to remove impurities. Or by filtration, the insoluble substance is separated; or by crystallization, the pure precipitation of diphenylguanidine is made. When crystallizing, the temperature and the amount of solvent are paid attention to, so that high-purity two-phenylguanidine can be obtained.
The entire production process is interconnected, and each step requires careful control by craftsmen to produce high-quality phenylguanidine to meet the needs of all parties.
What is the market price range of Diphenyl Guanidine?
The price of diphenylguanidine in the market is roughly in the range of tens to hundreds of yuan per kilogram. The change in its price depends on many factors.
The price of raw materials is the most important reason. If the production of raw materials is abundant and the supply exceeds the demand, the price may trend down; if the raw materials are rare and the demand exceeds the supply, the price will rise. And the preparation method is also related. The simple and efficient method can reduce the manufacturing cost, and the price may be slightly flat; if the preparation is difficult, costly and laborious, the price will increase.
The supply and demand of the city also affects the price. In the rubber, plastics and other industries, if there are many people who need to use diphenylguanidine, but the producers do not meet it, the price will increase; if the demand for the industry decreases, and there are many suppliers, the price may drop.
The difference in times and circumstances also makes the price different. In the world's prosperous economy, all industries are prosperous, and those who seek it are numerous, and the price may rise; if the economy is depressed, the industry is stagnant, and the demand is small and the supply is surplus, the price will drop.
Furthermore, the regulations of the government and the changes in taxes all have an impact on the price. The harsh regulations and the increase in taxes can increase the cost, and the price will also change accordingly. Therefore, the market price of diphenylguanidine often varies between tens of yuan and hundreds of yuan per kilogram due to various factors such as raw materials, supply and demand, time situation, and government orders.
