As an   Ethyl Acetate Plant , share with you. 1. The esterification reaction is a reversible reaction. In order to increase the yield of esters, the reaction must be made as far as possible to facilitate the formation of esters. Generally, one of the reactants acid and alcohol is made in excess. In industrial production, which excess is better depends on the availability of raw materials, whether they are cheap, and whether they are easy to recycle. In the laboratory, an excess of ethanol is generally used. The mass fraction of ethanol should be high. It would be better if the ethanol with a mass fraction of 95% could be replaced by absolute ethanol. The amount of concentrated sulfuric acid used in the catalysis is very small. Generally, the catalysis can be completed as long as the mass of sulfuric acid reaches 3% of the mass of ethanol. However, in order to remove the water generated in the reaction, the amount of concentrated sulfuric acid should be slightly larger. 2. When prep...

As a   Hydrogen Peroxide Manufacturing Plant , share with you. Steam running at the bottom of the distillation tower (that is, heating steam fleeing into the residual liquid and overflowing) is generally caused by the large amount and pressure of heating steam. At this time, the amount and pressure of steam can be reduced appropriately. If the liquid level of the residual liquid in the heating kettle at the bottom of the tower is too low (less than 1/2 of the total height of the tower kettle section), the phenomenon of less liquid and more vapor will also occur when the spent grains are discharged. Distillation Technology The solution is to temporarily close down or close the outlet valve to increase the liquid level and maintain the residual liquid height in the tower kettle section. When using a buoy-type drainer, if the buoy is stuck and cannot fall, it will also cause excessive discharge of the waste liquid. Therefore, we must pay attention to the mechanical failure of the drai...

As a   Formaldehyde Production Plant , let me share with you. Formaldehyde production technology is well-known for the wide range of uses of methylal, and its application is bound to involve all aspects of storage and transportation. When raw materials leave the factory, it is important to arrive safely. What are the precautions during transportation and storage and transportation? Formaldehyde Production Silver Process Long-term storage tanks should be equipped with breathing valves, the tanks should be sprayed with cold water in summer, and the tanks should be shaded and insulated if necessary. Give full play to the maximum use of raw materials, achieve the best product application, and complete safe production from the source to the end. The safety of the methylal transport fleet is more important than Mount Tai. Methylal is a first-class flammable liquid and is non-corrosive to metals. It can be stored in iron, mild steel, copper or aluminum containers. At the same time, due to...

  As a   Hydrogen Peroxide Manufacturing Plant , share with you. Composition and layout of distillation tower system The distillation tower system is composed of simple distillation tower, reboiler, condenser, reflux tank and other equipment. Generally, it is arranged as close as possible to form an independent operating system according to the sequence of the process and in compliance with the requirements of the specification. Similar equipment is centrally arranged. For example, the condenser is generally arranged on the third floor, and the return tank is arranged on the second floor. Distillation Technology On the floor, the reboiler is installed at the bottom of the distillation tower, and the pump is arranged on the first floor. This is not only neat and beautiful, but also convenient to operate. Due to the particularity of the reboiler, its related equipment and pipelines need to be carefully designed. Distillation tower system operation The liquid at the bottom of the...

As an   MMA Plant , share it with everyone. Nature and stability It is colorless and volatile liquid with strong spicy taste and flammable. Solubility: soluble in many organic solvents such as ethanol, ether, acetone, etc., slightly soluble in ethylene glycol and water It is flammable, stable, and easy to polymerize in the presence of light, heat, ionizing radiation and catalysts. It is explosive when mixed with air, and flammable when exposed to open flames, high temperatures, and oxidants; burning produces irritating smoke and chemically reacts with oxidants and acids. It should not be stored for a long time to prevent polymerization. Methyl Methacrylate Production Nature and stability: 1. It is volatile, flammable, and forms an explosive mixture with air. It is soluble in various organic solvents such as ethanol, ether, acetone, and slightly soluble in ethylene glycol and water. It is easy to polymerize by light, heat and catalysis, and can also be copolymerized with other monom...

As a   Formaldehyde Production Plant , let me share with you. Formaldehyde gas detector, formaldehyde gas detector is not a strong inspection equipment? The digital display on the formaldehyde detection equipment. It belongs to formaldehyde equipment as well as compulsory inspection equipment. Because it belongs to the detector equipment, and formaldehyde is a harmful gas. Formaldehyde Production Silver Process The figures on the formaldehyde complete equipment show the above conclusions. As for. The specification is the specific value specified. Therefore, it can be used to check whether the formaldehyde exceeds the standard formaldehyde equipment related issues, some of which have been specifically raised above and specific answers have been given. Come to understand and master very well, everyone can have a thorough knowledge and understanding. In this way, the talent is enough to apply what you have learned in practice, and at the same time, you can benefit a lot. So as to impr...

As a   Formaldehyde Production Plant , let me share with you. The formaldehyde production technology must keep clean the important parts of the machine operation. Any abnormalities such as noise, vibration, etc. found in the operation of mechanical equipment should be checked in time to prevent accidents. Lubrication is an important link in the daily maintenance of machinery. Wear is a major factor causing component failure. Maintenance is very important. Through inspection, timely effective preventive measures are taken, such as cleaning, lubrication, adjustment, tightening, and some checks on the technical status of parts and components, and some small workloads are made for the actual conditions. Repair, replace smaller parts, eliminate faults, reduce mechanical vibration and noise, and protect other parts from premature damage due to abnormal work. It is necessary to strengthen the management of the daily maintenance of machinery and take prevention as the principle of daily ma...
