acetal
In organic chemistry, this term refers to a specific functional group. It is often discussed in the context of protecting groups, where an aldehyde is converted into an acetal to prevent it from reacting during a multi-step synthesis, then later reverted to its original form.
In industrial and engineering contexts, the term is used as a shorthand for polyoxymethylene (POM). In this capacity, it describes a rigid, low-friction plastic used for precision parts like gears and bearings. While the chemical structure is the same, the register shifts from laboratory synthesis to material science and manufacturing.
Meanings
Examples
The chemist used an acetal to protect the carbonyl group during the reaction.
We should use acetal for these gears because of its low friction coefficient.
The synthesis of the acetal requires an acid catalyst to proceed efficiently.
Acetal is an ideal material for pump components due to its dimensional stability.
I wonder if the acetal bond will hydrolyze under these acidic conditions.
The lab technician carefully prepared the acetal solution for the experiment.

This high-strength acetal plastic resists wear better than most polymers.
