propionyl chloride from propionic acid?

i have propionic acid, and want to get propionyl chloride (aka Propionic Acid Chloride)

can this be done fairly easily?

This topic has been done to death!

UTFSE !!

Search, besides under propionyl chloride, for

Acetyl chloride
benzoyl chloride
cyanuric chloride
TCT
CC
phthaloyl chloride
oxalyl chloride

And here is one that is a waste of time

thionyl chloride

(simply because its bp is too close to the product's and as it is used in excess it is hard to seperate out.)

You'd do better just to use bromine and a few grams of red P as a catalyst... use an efficiant condensor and keep it shielded from light and you should be OK.

He's trying to make priopionyl CHLORIDE

Not alpha-bromoprioionic acid. The conditions you describe are for HVZ alpha-bromination.

Well I kinda figured he might be after that for a certain reaction.

You're a mind reader now?

I was trying to answer his questions as stated rather than making any assumptions about why he wants propionyl chloride or what he plans to make with it.

That puts us all on a slippery slope, doesn't it?
