As a kind of gas of no color and of light smell of ether, there are many similarities of physical property between liquefied petroleum gas and dimethyl ether, which can be free from such qualities of corrosion and carcinogenicity. At most 3700mL dimethyl ether will be dissolved in every 100mL of water, and additionally it may be easily dissolved in many kinds of organic solvents such as gasoline, carbon tetrachloride, acetone, chlorobenzene, and methyl acetate. More often than not dimethyl ether is hard to be activated under room temperature.
The traditional productive technology used to produce dimethyl ether can also be called two-step approach, which focuses mainly on the transformation of synthesis gas (consisting of carbon monoxide and hydrogen) into methanol. With copper-based catalyst as a type of acid catalyst, dimethyl ether will be created from the methanol that has been separated and purified.
Nonetheless, the one-step method designed and developed recently combines the two steps mentioned above together and helps to make the two reactions happen in one reactor. Then, the items such as methanol generated in the 1st step will be directly converted into dimethyl ether in situ without separation. Compared with two-step way, the one-step method features simple procedures and low costs. But the disadvantages can be seen in the fact that there’ll be abundant carbon dioxide emitted from the process and in the high investment for the first time. So there may be restriction in the applicable areas of industry. For now, the two-step method is often taken in the production of the most of dimethyl ether in industrial production.
One-step process of synthesis gas used to produce dimethyl ether is gaining an increasing popularity recently, and hydrogen peroxide plant largely reduces the cost of production by emerging the two steps into one and shortening the production processes and reducing the frequent use of dimethyl ether plant.
Dimethyl ether plant is mainly used to replace liquefied petroleum gas to burn and then plays the role of automobile fuel in platform diesel.
Moreover, dimethyl ether can also serve as aerosol, freezing medium, vesicant, and industrial chemicals that play a fundamental role in the production of dimethyl sulfate, dimethyl carbonate, alkyl halide, etc.
Dimethyl ether as a sort of new and clean energy and a role of supplement of traditional energy can be used to replace gasoline, diesel, liquefied gas, natural gas, etc. The merit in the replacement of liquefied gas can be seen in advantageous price. Therefore, we will see a positive effect in reducing life burden with its low price of dimethyl ether.
