Reaction of Red Phosphorus and IsopropvlThe reaction of red phosphorus with potassium alcohol was a substitution reaction, and the reaction formula was CH3- CH(SH) -CH3 +I2(P)→ CH3-CHI-CH3 +HOI, where P13 was the catalyst. In addition, the red phosphorus was mixed evenly with the alcohol, placed in a ball mill tank, and ball-grinded under a protective atmosphere, then washed with alcohol and dried to obtain the ball-grinded red phosphorus.

There was no reaction from the red dots on his bodyIf there are small red spots on the body and there is no reaction, it may be a cherry-like hemomaly, commonly known as "red mole" and "senile hemomaly". It is mostly caused by the local capillaries of the skin. It is usually a manifestation of skin aging. The appearance of young people may be related to hormonal changes.(For example, pregnant women and people with high mental stress). It is not harmful to health and does not require special care. Pay attention to sun protection and avoid rubbing and scratching. If it affects the appearance, you can go to the Dermatology Department of a regular hospital to remove it by laser, freezing or electrocoagulation.
However, there were other possibilities. For example, spider moles often appear on the neck and chest. There are red blood vessels around the red spots. When the red spots and red blood vessels disappear when pressing, they appear after releasing the hand. This may indicate that the liver function is damaged. The liver cannot regulate the body's estrogens, causing estrogens to accumulate in the body and stimulate the blood capillaries to swell and expand.(This may happen with chronic viral infections, liver cancer, and other diseases, but it is normal for adolescent girls and pregnant women to have spider moles due to increased levels of estrogens in their bodies. Don't worry, they will disappear with age or after giving birth.)
It could also be a needle-like bleeding point caused by a decrease in the number of blood capillaries and a problem with the blood clot function. This kind of bleeding point would easily turn into a large bruise after bumping into it. Other parts of the body such as gums, oral mucus, nasal cavity, etc. might also bleed abnormally. In addition, viral infections (such as infant rash, chickenella, rubella, measles, etc.) may also appear as red spots on the body in individual cases, but it is generally accompanied by a certain degree of upper respiratory tract infection symptoms, fever, and mild itching. Family genetic factors may also cause some people to develop cherry-like hemomalies earlier. If the red dots persist or increase in number, it is recommended to seek medical examination to determine the cause.

4. Discussion on the reaction mechanism of red ceramic colorIn terms of the reaction mechanism of Fe-ZrSiO2 red ceramic color:
1. ** Ion migration and synthesis difficulty **
- In the high-temperature reaction, ZrSiOx could not migrate in a large range during the reaction, which was different from the rapid migration of coloring ions in the preparation of H%#$%'() and 9#$%'(). This was one of the reasons why Fe-ZrSiOx red ceramic color was difficult to synthesize.
2. ** Relationship between color and ingredients **
- In the synthesis of the color, due to the different chemical ratio of the raw materials and the different selection of raw materials, the synthesized color would present two main colors: one was H 'KLM, and the other was>:%N;M.
- In the preparation process, when the chemical composition of the raw materials has a certain ratio (such as-0), it is beneficial to the preparation of the pink material. This may be because in the high temperature stage, a certain substance (such as/*() and phase, thus providing a channel with little resistance for the spread of 1276, increasing 12.
3. ** Effect of Mineralizing Agent Usage **
- The dosage of the mineral was very important. When there was too little mineral, the color would be impure and pale. This was because the 1276 package had arrived! "%。When there were too many minerals, the color would change to purple-yellow, and the product would become a harder block, which would make the grinding process difficult. The dosage of the mineral in the synthesis was generally $8,9,8;0.
4. ** Controlling factors of reaction order **
- In the red package reaction mechanism, the reaction time sequence of different substances was an important issue that affected the efficiency of the package. The first method to control the reaction sequence was temperature.
