Method of manufacturing dimethylsiloxane hybrid cyclic
Dimethylsiloxane hybrid cyclic (DMC) is an important organosilicon compound, which is widely used in the fields of chemical industry, electronics and medicine. In this paper, a manufacturing method of dimethylsiloxane hybrid cyclic body will be introduced.
I. Raw materials and equipment
1. Raw materials: methanol, silica powder, catalyst (such as sulfuric acid, hydrochloric acid, etc.).
2. Equipment: reactor, condenser, stirrer, storage tank, pump, etc.
2. Manufacturing steps
1. Add methanol and silica powder into the reaction kettle according to a certain proportion, and add catalyst at the same time.
2. Turn on the stirrer to mix the raw materials fully.
3. Heating the reactor and controlling a certain reaction temperature, so that the methanol and silica powder react to produce dimethylsiloxane mixed cyclic body.
4. Condense and collect the mixed cyclic dimethylsiloxane produced by the reaction through a condenser.
5. At the end of the reaction, stop heating and stirring, and separate the mixture in the reactor to obtain the dimethylsiloxane mixed cyclic body product.
3. Precautions
1. Strictly control the ratio of raw materials and reaction temperature to avoid generating by-products or affecting product quality.
2. The selection and dosage of catalyst have great influence on the reaction speed and product quality, which need to be adjusted according to the actual situation.
3. Sufficient stirring should be maintained during the reaction to ensure the homogeneous mixing of raw materials.
4. Sufficient separation and purification are needed after the reaction to ensure product quality.
4. Advantages and Prospects
The method adopts conventional chemical equipment and technology, which is easy to operate, low cost and suitable for large-scale production. Meanwhile, dimethylsiloxane mixed cyclic body has a wide range of application prospects, especially in the field of silicone materials, electronic products, medicine and other fields have a high demand. Therefore, the method has better economic and social benefits.
In conclusion, the manufacturing method of dimethylsiloxane hybrid cyclic body is an important chemical technology, which is of great significance for promoting the development of the organosilicon industry.
