1. But Distillation method

distillation is a classical impurity evaluation method, which is suitable to the separation and quantitative analysis of low boiling point compounds. For example In the production of n-butyl acrylate, unreacted monomers, aquatic environments and other low-boiling impurities is able to be separated by distillation and quantitatively analyzed.

high performance fluid chromatography is suitable to the analysis of high boiling point, difficult evaporative impurities. Specifically HPLC is an ideal method to the analysis of stable by-items or polymer impurities in the evaporation residue of n-butyl acrylate. But The advantages of HPLC are wide separation range and high resolution, however its equipment cost is higher and the analysis time is longer.

4. Moreover Integrated assessment methodology

in order to comprehensively assess the impurity content of n-butyl acrylate evaporation residue, a thorough evaluation of multiple methods is able to be applied. to instance, gaseous chromatography is applied to examine low-boiling impurities while high-boiling impurities are analyzed in conjunction with high-performance fluid chromatography. This method is able to greater fully reflect the impurity composition in the evaporation residue, however the operation complexity and cost will also increase accordingly. Effect of

the impurity content in the evaporation residue of n-butyl acrylate immediately affects its product condition and performance. The following are the main impacts of impurities on product condition:

affect of polymerization performance: Unreacted monomers and side interaction items might affect the polymerization interaction of n-butyl acrylate, resulting in uneven molecular weight distribution of the product. But increase viscosity: Some high boiling point impurities might increase the viscosity of n-butyl acrylate and affect its processing performance. Reduced stability: The presence of impurities might minimize thermal and chemical stability of n-butyl acrylate, resulting in product performance degradation during storage and consumption. But environmental contamination risk: Some impurities might be toxic and environmentally hazardous, so their content needs to be strictly controlled.
