Tetraethyl Orthosilicate Synthesis
The method of synthesizing ethyl orthosilicate
If you want to synthesize ethyl orthosilicate, you must understand the reason and follow the method.
Prepare all materials first, silicon sources, ethanol and the like, all need to be pure and good. Silicon sources have excellent texture, no impurities and no filth; ethanol, the degree is appropriate, and the character is pure.
As for the method, or phase with silicon and ethanol. Silicon is placed in the device, and ethanol is slowly injected into it. The temperature and pressure between them need to be carefully adjusted. If the temperature is high, the rate of melting is difficult to control, and if the temperature is low, it will be slow and time-consuming. The size of the pressure is also related to the success of the transformation. Under the right temperature and pressure, the two are phased, and various reactions occur, and then there is the germination of ethyl orthosilicate.
Or use other methods to prepare silicon halide and alkoxides. Choose the pure silicon halide, and the alcohol salt is matched with the essence. When the two meet, they should be combined according to their nature, and in the right environment, so that the reaction can proceed smoothly. When the reaction is completed, add various agents to promote it, or control the time to control it.
When the reaction is completed, there must be various heterogeneous mixtures. It is necessary to use delicate techniques to remove the heterogeneity and keep it pure. Or use the method of distillation, according to the difference of boiling, to separate the ethyl orthosilicate from other things, and raise it and condense it to obtain a pure product. Or use other methods to purify, so that ethyl orthosilicate can reach a very high purity, so that it can be used for various purposes.
In short, the synthesis of ethyl orthosilicate is not easy. It is necessary to do everything in detail in materials, methods, controls, and mentions to get the best product.
