What is the safety of transfluthrin (ISO); 2,3,5,6-tetrafluorobenzyl (1R, 3S) -3- (2,2-dichlorovinyl) -2, 2-dimethylcyclopropanecarboxylate
Wen Jun inquired about transfluthrin (that is, tetrafluoromethrin), whose chemical name is 2,3,5,6-tetrafluorobenzyl (1R, 3S) -3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate. The safety of this substance is quite important, so let me elaborate.
Tetrafluoromethrin is commonly used in various hygiene insecticides, such as mosquito coils, electric mosquito coil liquids, etc. In these products, the content is usually low, and when used reasonably, it is relatively safe for most people. The reason is that the dose range that the human body can tolerate has been fully considered when designing such products.
However, safety is not absolute. If exposed to this substance for a long time and at high concentrations, it may have certain effects on the human body. For example, some individuals may be sensitive to it, and symptoms such as skin allergies and respiratory discomfort may occur after exposure. In addition, if you accidentally eat products containing tetrafluoromethrin, it may also cause adverse reactions, such as nausea, vomiting and other digestive symptoms.
At the same time, for special groups, such as infants, pregnant women, the elderly and those with respiratory diseases, because their bodies are more sensitive or fragile, it is more necessary to use products containing this substance with caution. When using, ensure that the environment is well ventilated to minimize the risk of exposure.
Furthermore, from an environmental perspective, although tetrafluoromethrin has a small impact on the environment under normal use, its large and unreasonable use may still cause potential harm to the ecology and affect some beneficial insects and aquatic organisms.
Therefore, in general, tetrafluoromethrin is safe when following the correct use methods and precautions; however, it must not be taken lightly during use, and various factors need to be fully considered to ensure human health and environmental safety.
Transfluthrin (ISO); 2,3,5,6-tetrafluorobenzyl (1R, 3S) -3- (2,2-dichlorovinyl) -2, what is the production process of 2-dimethylcyclopropanecarboxylate
The process of preparing transfluthrin (ISO); 2,3,5,6-tetrafluorobenzyl (1R, 3S) -3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropane carboxylate) is a delicate and complicated matter.
Its starting materials need to be carefully selected. 2,3,5,6-tetrafluorobenzyl alcohol and (1R, 3S) -3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanoyl chloride are the most important. These two are unique in nature and need to be properly stored to prevent deterioration and affect the quality of the product.
The environment of the reaction is crucial. In suitable solvents, anhydrous organic solvents, such as dichloromethane, are often selected to ensure a smooth reaction. Temperature control should not be ignored, usually starting at low temperature, slowly heating up, so that the reaction proceeds in sequence. In the meantime, the stirring speed should also be moderate, so that the raw materials are uniformly mixed and the reaction is fully promoted.
Catalytic substances can accelerate the reaction. Organic bases are often used as catalysts, such as triethylamine, etc. However, the dosage must be accurately weighed. Too much will cause side reactions to occur, and too little will cause slow reactions.
After the reaction is completed, the separation and purification of the product is also the key. Column chromatography or recrystallization are the main methods. In column chromatography, choose the appropriate filler and operate it carefully to separate the product from impurities. Recrystallization requires finding a suitable solvent, and the speed of cooling and crystallization is related to the purity of the product.
During the entire preparation process, every step needs to be cautious. A slight difference will lead to impure products or low yields. Those who need to be prepared with exquisite skills and rigorous heart can obtain high-quality trans-cyfluthrin.
