About Dimethyl Ether:

It is a synthetically produced alternative to diesel for use in specially designed compression ignition diesel engines.
It can be produced indigenously, and several countries, like Japan, USA, China, Sweden, Denmark, and Korea, are already using DME to power their vehicles.
The DME-fuelled engine emitted extremely low particulate and soot emissions and almost no smoke without using expensive exhaust gas after-treatment devices and advanced engine technologies.
It can be a viable alternative fuel and engine technology to adapt to conventional diesel engines used in India’s economy’s agricultural and transport sectors.

Properties of Dimethyl Ether

It has a very high cetane number, which is a measure of the fuel’s ignitibility in compression ignition engines.
Under normal atmospheric conditions, DME is a colorless gas.

Application of Dimethyl Ether

It is used extensively in the chemical industry and as an aerosol propellant.
It is used in chemical industries and also to produce dyes and plastics.

Q1) What is An aerosol?

An aerosol is a suspension of fine solid particles or liquid droplets in a gas. It can refer to either a natural phenomenon, such as atmospheric aerosols, or to man-made products, such as aerosol sprays.
