2-amino-5-nitrothiazole storage conditions are a white or light pink crystalline powder. It is easily soluble in ethanol, ethyl ether, benzene, trichloromethane, petroleum ether, and soluble in about 200 parts of water, and its solution is red when it meets ferrite salt. Today, Hebi Sake Chemical Co., LTD., a manufacturer of 2-amino-5-nitrothiazole storage conditions, will show you how to equip 2-amino-5-nitrothiazole storage conditions and calculate the chemical data.
It is produced by the reaction of pyridine with ferric chloride. Mixing 70g anhydrous pyridine with 13g anhydrous ferric chloride was heated in a sealed tube at 300℃ for about 35h. After cooling, the reactants solidify into red-black crystals. Open the sealing tube and wash out the red-black solution of the solid with a little hot water. The oily impurity is removed by ether extraction. After neutralization with sodium bicarbonate, excess pyridine is removed by steam heating. The mixture is then adjusted to a strong base and steam out 2,2'-2-amino-5-nitrothiazole storage conditions. After acidification, the product is evaporated and concentrated, and then sodium hydroxide is added. The product is extracted with ether, and the ether is removed to obtain crude product. The crude product is recrystallized with B, and the activated carbon is decolorized. In addition, the product can also be prepared by the reaction of α-methylpyridine [109-06-8] with potassium permanganate and purified treatment.

introduction to dust collector When the dust-bearing gas enters the dust collector from the intake tuyere, it first encounters the inclined plate and baffle in the middle of the intake and outlet tuyere, and the air flow turns to flow into the ash hopper. At the same time, the air flow speed slows down. Due to the effect of inertia, the coarse particles in the gas flow directly into the ash collector. introduction to dust collector refers to the method of blowing compressed air to remove the dust attached to the filter medium (cloth bag or filter cylinder); According to the size of the dust collector may have several groups of pulse valves, controlled by the pulse controller or PLC, each time open a set of pulse valves to remove the dust of the part of the bag or filter cylinder it controls, and other bags or filter cylinder work normally, after a period of time, the next set of pulse valves open, clean the next part of the dust collector by the ash bucket, the upper box, the middle box, the lower box and so on. The upper, middle and lower boxes are divided into compartments. When working, dusty gas enters the ash bucket from the inlet air duct, coarse dust particles directly fall into the bottom of the ash bucket, fine dust particles enter the middle and lower boxes upward with the airflow turning point, dust accumulation is attached to the outer surface of the filter bag, filtered gas enters the upper box to the clean gas collection tube - exhaust air duct, and is discharged to the atmosphere by the exhaust fan.
introduction to storage and installation requirements of filter bags in dust collector
1. Filter bag installation requirements: It is recommended that two people install the bag. One person folds the cloth bag lengthwise into the hole of the flower plate, and the other person grabs and opens the filter bag into a roll. The cage should be centered, gently placed, and installed vertically.
2. Installation personnel should be dressed in concise clothes with clean pockets. Cigarettes, matches, lighters, keys, knives and other items should not be carried to avoid falling into the filter bag. (If any debris falls into the filter bag, remove it). Do not wear shoes with iron nails or hard soles for installation.
Three, after the installation of the flower board should be gradually covered with canvas, so as to avoid debris falling into the filter bag. Spray pipe installation should also be covered with canvas flower plate, to prevent damage to the filter bag mouth.
4. During the installation of the filter bag, smoking is prohibited, welding and cutting in any form or part is prohibited, lighting lighting with lighters and matches is prohibited in the case of power failure. After the installation work is finished every day, the installation tools should be counted to avoid missing into the filter bag and damaging the filter bag.
Five, filter bag installation inspection: after each installation of a filter bag, it is necessary to check whether the joint joint is sealed and whether the sealing position is correct. Check whether it is vertical from the ash hopper. If it is found that the bottom of the filter bag meets or is incorrect, it is necessary to make a record and adjust it in time under the guidance of the specially-directed person.
Vi. Installation environment requirements: The lighting at the installation site is sufficient, and no equipment or sundry that has nothing to do with installation is allowed to be stored at the site.
7. When storing the filter bag, it should be kept away from fire, avoid direct sunlight and other strong light, and prevent heavy objects from squeezing. Each filter bag should be inspected before installation to prevent mechanical damage.
introduction to dust collector is mainly composed of filter bag, flight removal mechanism and shell ash hopper. The air flow enters from the air inlet pipe and enters the dust hopper through the air inlet valve and the air inlet elbow. Under the action of the flow guide plate, the large particles of dust directly enter the dust hopper, while the small dust flows evenly to the box. The box body is divided into two parts: the clean air chamber and the dust chamber. When the dust-containing gas enters the clean gas chamber through the ash hopper filter bag, the dust is intercepted by the filter bag and forms a dust layer on the outer surface of the filter bag. In fact, fine dust particles are captured by dust layers, known as secondary filters.
