A heat sensitive product generally refers to a substance that decomposes, polymerizes, or otherwise reacts at a high temperature. Using a conventional distillation still or column distillation, since the film formed by the material is very thick (usually the diameter of the distillation still or the distillation column), the material takes a long time in the kettle or the column, causing heat for a long time, which easily causes a reaction and affects product. Our company has accumulated many years of research experience to provide customers with system solutions for the refining and purification of heat sensitive products.
