Definition - What does Amide mean?
Amide is a type of compound that is classified under organic groups. The most common form includes organic amides, as well as the more essential types like phosphor amides.
Amide generally refers to the compound classes or ammonia's conjugate base.
Amide is also known as acid amide.
Corrosionpedia explains Amide
The simplest form of amides are known to be ammonia derivatives, where one atom of hydrogen has been swapped by an acyl group. They are considered neutral, in contrast to their close kin called amines, which are basic in nature.
This compound plays a big role in the corrosion behavior of carbon steel. Take for example carbon steels, which are submerged in acidic solutions with the presence of amide. Based on various investigations, amides like ethoxylated fatty amide, along with various types of ethylene oxides, can inhibit corrosion of carbon steels immersed in hydrochloric solutions. This was identified through galvanostatic and weight loss methods.
However, the corrosion inhibition properties of amides also depend on certain variables, such as pressure and temperature. As the pressure or temperature elevates, the corrosion rate also increases; thus, the corrosion inhibition of the amide also decreases. This can be brought on by many factors, such as adsorption in the case of elevating temperature.
Amides also play a vital role in technology and nature. Amide linkages form easily, and are rigid and resistant to hydrolysis, making them very resilient. One example is nylon.
