What is the production process of 4- (difluoromethoxy) trifluorotoluene?
The process of manufacturing 4 - (diethylamino) triethylamine is obtained from the raw materials of diethylamine and triethylamine. The process is roughly as follows:
Take the first amount of diethylamine and place it in the reactor. Diethylamine, the color solution, has an ammonia odor, and its chemical activity is an important starting point for this reaction. However, under specific conditions and conditions, triethylamine is added. Triethylamine is also the color solution, which has a strong ammonia odor, and is an important reaction component in this reaction.
The process of adding triethylamine needs to be tightly controlled. Usually, the initial reaction should be maintained at 20-30 degrees Celsius. This degree of resistance can make the molecules of diethylamine and triethylamine suitable, increase the effective collision rate, and promote the reaction rate. If the degree of resistance is high, the reaction rate will increase, but the side reaction rate may also increase, affecting the product's performance. If the degree of resistance is low, the reaction rate will be low, and the consumption will be low, which is not conducive to the production efficiency.
After adding the reaction rate, increase the reaction rate of the reaction kettle to 50-60 degrees Celsius, and keep the reaction time. The purpose of mixing is to make the diethylamine and triethylamine fully mixed, so that the reaction rate is more uniform. In this case, the reaction rate of the two molecules is accelerated, and 4 - (diethylamino) triethylamine is generated.
After the reaction is completed, the reaction mixture will be prepared. First, the diethylamine and triethylamine that are not reversed are removed by the method of steaming. The boiling of the two is different. According to this characteristic, they can be steamed out in sequence in the environment of the warehouse to achieve the initial separation effect. However, the residue is refined to obtain a high degree of 4- (diethylamino) triethylamine. In the process of refining, it is necessary to control the degree, force and flow rate, etc., in order to ensure the quality of the product.
In this way, the multi-step operation can obtain 4- (diethylamino) triethylamine products. Its manufacturing process needs to be carefully controlled by each method in order to obtain high-quality products.
What is the price range of 4- (difluoromethoxy) trifluorotoluene in the market?
Nowadays, there is dihydroxyethyltriethylamine, and the price in the market is difficult to generalize. The price of the cover often changes for various reasons.
First, the price of raw materials is also. The production of dihydroxyethyltriethylamine requires specific raw materials. If the price of this raw material rises or falls, the price of the finished product will also be affected. If the price of raw materials changes due to time, origin, supply and demand, etc., the price of dihydroxyethyltriethylamine will move accordingly.
Second, the situation of supply and demand. There are many people in the market who want it, but the supply is small, the price will rise; if the supply exceeds the demand, the price will fall. For example, at a certain time, the demand for dihydroxyethyltriethylamine in a certain industry has increased greatly, but the manufacturer has not increased the supply, and the price will rise; on the contrary, if there is no large demand and there are more manufacturers, the price will tend to be lower.
Third, the difference in quality. Those with different quality have different prices. Those with better quality, refined craftsmanship, and less impurities are more suitable for many uses, and the price is often high; those with inferior quality have lower prices.
Fourth, the difference between manufacturers. Different manufacturers have different pricing due to differences in technology, cost, and reputation. Large producers, with good technology, good cost control, and prestige, have stable or competitive prices; small producers may have low prices or fluctuate greatly with the market due to cost and other reasons.
Roughly speaking, the price per kilogram may be between tens of yuan and hundreds of yuan. However, the market situation changes, if you want to know the exact price, you must consult the supplier in real time and observe the market situation.
What should be paid attention to in the storage and transportation of 4- (difluoromethoxy) trifluorotoluene?
Bis (hydroxyethoxy) triethoxy silane, when storing and transporting it, be sure to pay attention to many matters.
At the storage end, the temperature and humidity of the first environment. This substance should be stored in a cool, dry and well-ventilated place, and must not be placed in a high temperature or humid place. If it is at high temperature, its chemical reactivity may increase, causing the substance to deteriorate; and humid environment, it is easy to cause adverse reactions such as hydrolysis, which will damage its quality. And it needs to be kept away from fires and heat sources. Because the product may be flammable, it may be dangerous to encounter open flames and hot topics.
Furthermore, storage containers are also crucial. Containers of suitable materials are selected, generally corrosion-resistant materials are preferred to prevent the container from reacting with the substance and affecting its properties. At the same time, the container must be tightly sealed to avoid excessive contact with the air to prevent oxidation or absorption of water vapor in the air.
As for transportation, the packaging must be stable. Make sure that the packaging material can withstand the vibration and collision during transportation, and will not be damaged and leaked. Transportation vehicles should also be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment for emergencies. During transportation, the route planning should also be prudent, avoiding sensitive areas such as water source reserves and densely populated areas. And transportation personnel should be familiar with the characteristics of the substance and emergency response methods. In case of emergencies, they can respond quickly and properly to ensure transportation safety. In this way, the storage and transportation of di (hydroxyethoxy) triethoxysilane can be taken into account to avoid accidents.
