acryloyl chloride problem

Quote from:

Most monomers come with a stabilizer like MEHQ or BHT. I'm a bit surprised, but acryloyl chloride does too according to Sigma's site (I'd expect an acid chloride to react with a phenol). If your monomer did not come with a stabilizer, you should add a small amount. This will prevent polymerization.

It came with phenothiazine as a stabilizer

There is also a strong possibility that there is a bunch of acrylic acid in there. Acryloyol chloride hydrolyzes even more easily than it polymerizes.

You should keep it cold to minimize both of these.

I kept it in the refrigerator but nothing occurs, i think it is a polymer rather than acid as acrylic acid is also a liquid not solid.

Acryl compounds polymerize easily. What you can try is to put it in a round flasked and heat it up and do dry destillation. So you can get some monomer back.

Thank you Sir
Does this process need a specific condition? since leakage of acryloyl chloride vapors are very dangerous.
Could you specify the distillation procedure from safety point of view?
How to avoid polymerization again?
