Fourth, in daily life, the compound is also accompanied everywhere. Food seasoning, salt, sugar, vinegar, etc., or through chemical synthesis and refining, to increase the taste of diet. Cleaning products, such as soap, detergent, etc., are synthesized to decontaminate and purify things and keep life clean. Even wax, oil used for lighting, or through chemical synthesis to brighten human settlements and make it easier for people to walk.
All these, the compound is of great use in medicine, farming, manufacturing, and daily use. It is fundamental to people's livelihood and the development of society.

The synthesis of a chemical compound involves many factors, and today it is based on ancient methods. The details are as follows.
Bear the brunt, and the selection of raw materials is the key. Those with pure texture and good quality must be selected to be a good foundation for synthesis. As the ancient law says: "The source is clear, the flow is clean, and the original is solid, the branch is prosperous." Selecting raw materials is like finding the source and solidifying the foundation. If the raw materials are impure, everything will be difficult to follow.
As for the steps of synthesis, it needs to be gradual and orderly. First, mix all the raw materials in a certain proportion. This ratio is like weighing the weight, and the slightest difference may lead to the failure of the synthesis. Gu Yun: "The slightest difference is a thousand miles away." It can be seen here. The compatibility is established, and it is part of the reaction. Either heat to promote its change, or apply pressure to change its properties. When heating, the control of the heat is crucial. If the fire is fierce, the material will be easy to burn, and if the fire is small, it will become insufficient.
Furthermore, the reaction environment should not be underestimated. The humidity of the air and the temperature can affect the effectiveness of the synthesis. It is advisable to choose a quiet and clean place to avoid external disturbances and maintain the stability of the reaction.
After the reaction is completed, the purification of the product is also an important matter. To remove its impurities and leave its essence, pure compounds can be obtained. According to its characteristics, filtration, distillation and other methods can be used. < Br >

Now there is a question, what is the price range of a certain compound in the city. This is the important situation of the sincere business city, which is related to all things of business and trade. However, if you want to clarify its price, you need to look at many parties.
The price of the city of the merchant often varies according to the time, place, quality and quantity. The time, the change of the year, and the change of the season can make the price rise and fall. If the fruits and vegetables in time, when they are in full bloom, the price will be easy; if the times are difficult, the goods are rare and expensive, and the price will jump. The difference between the north and the south, the difference between far and near, also depends on the price. In the near-produced place, the freight is saved and the price may be cheap; in remote places, the transfer is difficult, and the price may be high. Quality, the quality of the goods, there is a difference between coarse and fine. Excellent products, with high-quality materials and exquisite craftsmanship, are expensive; poor products, the price is inferior. Measure, the number of supply and demand is also. If supply exceeds demand, the price will trend down; if demand exceeds supply, the price will rise.
As for this compound, if it is a common product for daily use, it is related to people's livelihood. In the city of Dayi, the price may be relatively stable, usually within a certain range. If it is a rare wonder, or the key to making important things, in a specific city, the price fluctuates or plays. However, it is difficult to determine the range of its price. It must be based on the current market conditions, and various factors must be widely observed before a relatively close number can be obtained. It is necessary to visit merchants and inquire experts, observe the price of their transactions, and measure the trend of their fluctuations.
