Production process of trimethylolpropane triacrylate
Thread Content
I would like to ask the experts in this field: since the product turns brownish-black after synthesis, how should the post-treatment process be prepared?
The brownish-black color may be caused by impurities or oxidation. Purification methods such as recrystallization, distillation, filtration, or treatment with adsorbents can be considered. The specific process needs to be determined based on laboratory conditions and product requirements. It is best to optimize the raw materials and reaction conditions to reduce the likelihood of side reactions. .
We plan to use strong acid resin instead of sulfonic acid, but the color resulting isn’t quite right
Original poster, are there any good methods for dealing with products that have such a high color intensity?
