A partial summary of the uses of dimethyl ether.
Thread Content
1. Household fuels: 1. Dimethyl ether liquefied gas – as a substitute for or additive to liquefied petroleum gas. 2. Dimethyl ether as an additive to city gas or natural gas. 3. Other uses of dimethyl ether, such as in welding gases. II. Fuel for vehicles: 1. Dimethyl ether as a direct substitute for diesel; 2. Dimethyl ether as a substitute or additive for alcohol-based fuels; 3. Dimethyl ether as an additive in aviation kerosene. III. Substitutes for chlorofluorocarbons: 1. Aerosols; 2. Refrigerants; 3. Foaming agents. IV. As raw materials in the chemical industry: 1. As an alkylating agent; 2. As a coupling agent; 3. Reacting with ethylene oxide; 4. Being converted into low-carbon olefins. This is entirely based on my own summary. Thank you, let’s exchange ideas together.
Dimethyl ether to olefins is the most attractive option!
So many people are using dimethyl ether these days; I wonder if it will have the same consequences as methanol: L
Is dimethyl ether suitable as a welding gas? Its calorific value is a bit too low
Then it’s better to use methanol to directly produce olefins.
It can be welded; its burning temperature is high
**It is stipulated that it shall not be used as a substitute or additive for liquefied petroleum gas.
