The synthesis method of 2% 2C6-dimethyl ether covers several routes, all of which are aimed at the formation of this compound.
One method can be obtained from the dehydration of methanol. In this case, methanol is heated under the action of a suitable catalyst and dehydrates. The catalyst used is usually such as γ-alumina. A molecule of water is removed from the methanol molecules, and it is formed into 2% 2C6-dimethyl ether. The reaction mechanism is that the hydroxyl group in the methanol molecule combines with the hydrogen atom of the adjacent methanol molecule to form water, and the rest is connected to ether.
Another method is directly prepared from the synthesis gas. The synthesis gas is a mixture of carbon monoxide and hydrogen. In this process, a specific bifunctional catalyst is required. This catalyst can simultaneously promote the conversion of synthesis gas to methanol and the further dehydration of methanol to ether. This path can be achieved in one step, without the need to first obtain methanol and then dehydrate, simplifying the process, but the catalyst requirements are quite high. The reaction conditions also need to be finely regulated. Factors such as temperature and pressure are all related to the efficiency of the reaction and the selectivity of the product.
In addition, there are also methods for preparing halogenated hydrocarbons by reacting with sodium alcohol. The halogen atoms of halogenated hydrocarbons are active and easily react with the alkoxy groups in sodium alcohol to generate corresponding ethers. In this reaction, the choice of halogenated hydrocarbons and sodium alcohols needs to meet specific structural requirements to obtain 2% 2C6-dimethyl ether. And the reaction environment also needs to be suitable. The choice of solvent and the control of reaction temperature have a great impact on the reaction process.
The above methods have advantages and disadvantages. Methanol dehydration technology is relatively mature, so methanol needs to be prepared first; synthesis gas direct process is simple, but the catalyst and reaction conditions are harsh; halogenated hydrocarbons and sodium alcohols reaction method requires high raw material structure. All methods are efforts in chemical synthesis to obtain 2% 2C6-dimethyl ether efficiently and with high quality.
