The batch of DOP that our company just produced had a normal color in its crude ester form, but once it reached the neutralization tank, its color turned red. The water resulting from the neutralization process was also red. Upon sampling and observing it under light, the color faded after some time. What could be the reason for this? ? Those who know or have experience, please help analyze it!

I want to know too! What substances are inside?

This is caused by the phthalic anhydride issue; I have encountered it as well
