Dear Friends-

Hello to all,

I am in process of getting quotation for 1,3-Butadine chilling package from vendors, wherein butadine is required to be chilled to 8 deg C, in order to avoid "polymerization" during its transfer & storage.

In order to ensure avoidance of polymerization, vendor has put-up the query regarding temperature, at which polymerization phenomenon is likely to take place.

Here, I do not know how to determine polymerization temperature, even with HYSIS. The stream conditions are 5.5 kg/cm2g pressure & 0 deg C temperature.

The composition of 1,3-Butadine is attached herewith.

Your kind help is requested for determination procedure.

Regards,

Hi ,
Talk to your supplier . FYI all those monomers are inhibited .

The answer will depend on how well Oxygen is excluded from the mixture in your process. Butadiene reacts with O2 to form a peroxide, which initiates Butadiene to polymerize. The peroxide is not very soluble in the Butadiene and is more dense than Butadiene, so eliminate any pocket where it may accumulate! See the attached, it may help.
