Taizhou Alkaline Reaction Kettle Melting Effect Principle
The melting effect of the natron reaction kettle was mainly due to the dissolving process. First, the solid soda ash (soda ash) was put into the reaction kettle according to a certain proportion, and then a certain proportion of clean water was added. After sealing, it was heated. The mainstream heating method was steam heating (if the local environmental protection allowed, the direct heating method could also be used). Since the soda ash would not be dissolved at room temperature, it needed to be heated to a temperature of about 165 degrees. During the process of maintaining the temperature of about 165 degrees, the reaction kettle continued to rotate and stir (for example, the drum type reaction kettle was rotated as a whole), so that the raw materials were heated more sufficiently, so that the heating was more uniform, and thus the effect of high-efficiency dissolution was achieved. After 2 to 3 hours, it could be completely dissolved into liquid soda ash. Read more exciting novels for free
Working Principle of Lifting Temperature-Controlled Reaction Kettle
The working principle of a lift-type temperature-controlled reactor (such as a tabletop lift-type reactor, a quick-opening lift-type reactor, etc.) mainly involved height adjustment, temperature control, and so on. In terms of height adjustment, the height and angle of the reactor were adjusted by the electronic control system to adapt to different reaction conditions and operational requirements. In terms of temperature control, different types of reactors had different temperature control methods. The first method was to use a heating/cooling system, such as a temperature-controlled oil heater for the reaction kettle. There were generally two ways to cool the reaction kettle. One was to use water to heat the medium to cool down. The equipment was connected to the cooling water circulation port. When it received the cooling command, the cooling electromagnetic valve would automatically open to circulate the cooling water to directly cool the reaction kettle to achieve a rapid cooling effect. Another method of temperature control was similar to a glass reactor. Through the double-layered reactor, a constant temperature (high or low temperature) hot solution or cooling liquid was injected to heat or cool the materials in the reactor at a constant temperature. It could also provide agitation, so that the medium in the reactor (such as freezing liquid, heating water, or heating oil) could be stirred to perform a circular reaction to achieve heating or cooling. There was also the water bath temperature control method, which placed the reaction kettle in the water bath, and used the heat capacity and heat transfer effect of the water bath to control the temperature of the reaction kettle through the principle of heat balance. The oil bath temperature control method placed the reaction kettle in the hot oil bath, and used the advantages of the high thermal conductivity and heat capacity of the hot oil to realize the temperature control of the reaction kettle. The kettle body was usually made of corrosion-resistant materials, such as stainless steel or special alloys, which could withstand corrosive substances such as strong acid and strong base to ensure the normal operation of the reaction. At the same time, during the reaction process, the stirrers could be used to mix and disperse the reaction materials to ensure the equality of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Alkaline reaction
The following is the reaction of some alklene under basic conditions: - In the nuclopathic epoxidation reaction, the electron deficient alkene could be epoxidized by hydrogen dioxide and tert-butoxyalcohol under basic conditions. Since the reaction was a nuclophile reaction, the epoxiidation could not proceed without an electron withdrawing group. - In the Julia-corona Asymmetrical Epoxidation Reaction, under the catalyst of the chiral-polyalpha-ammo acid, the electron deficient alkene was oxided by an oxidiser (hydrogen or ureido) under basic conditions to obtain a single configuration epoxide. - In the Payne Rearrangement Reaction, 2,3 -epoxy alcohol compounds are converted to 1,2 -epoxy- 3 -ol under basic conditions. This reaction is also known as the epoxy migration reaction. - In the laboratory, the reaction of the lithium salt and the lithium ether could be carried out under basic conditions. The lithium ether had an important catalyst activity in the reaction of alkene and the carbonylating reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Industrial reaction kettle
Industrial reactors can be divided into three types according to their structural forms: open (open), closed (closed), and semi-open and semi-closed; according to the heat transfer method, they can be divided into external circulation type, internal circulation type, and direct flow type; according to the heating medium, they can be divided into water-cooled, oil-cooled, and air-cooled jacket heating types. The materials of the reactor were carbon steel, stainless steel, and so on. The process includes putting the materials into the stirring tank for heating and stirring. After reaching the set temperature, close the feeding valve and then open the discharge valve. The materials transfer heat to the cooling tank through the heat exchange and then enter the splitter. The magnetic stirring rod in the splitter is used to clarify the liquid phase. After the liquid phase is filtered, it enters the measuring tank and then is recycled through the return pipe. The concentrated solid particles are processed. When cleaning, open the discharge valve and wash with a high-pressure pump. After checking that there is no problem, it can be put into use. If you need more information about industrial reactors, you can further consult the relevant information. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the effect of the reaction principle between elemental iodines and thiothiosulfates?
The principle of the reaction between elemental sulfur and sulfur dioxide was based on the oxido-reduction effect. In the reaction, the iodines were used as the oxidiser and the thiothiosulfates were used as the reducing agents. The sulfur atom in the sulfur dioxide is oxided, and the reduction reaction of the sulfur atom occurs. The reaction equation is: S O 2 + I → S O 2 + 2I. This reaction could be used in many application scenarios such as iodotitrations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
