Do alcoholic perfumes defile the hands, clothes, and air, and is it obligatory to interrupt the prayer due to the air being defiled by the scent of these perfumes?

What you mentioned about the air becoming impure from the smell of alcoholic perfumes is a kind of baseless whisper (waswas) and has no reality. The air does not become impure by this. It is most appropriate for one afflicted with whispers to adopt the easiest opinions in order to free themselves from hardship, and this is not an instance of blameworthy seeking out of concessions.
