GB/T 13255.4-2009 Part 4 For industrial caprolactone amide, the content of volatile alkali is determined by the Titrimetric method after distillation. It is suitable for all kinds of industrial caprolactone amide products. The sample is first distilled to separate the volatile alkali, and then the distillate is titrated with a suitable acid standard solution. The standard specifies the required instruments, such as distillingapparatus, Burette, etc., and specifies the preparation of reagents. Detailed description of Sample Handling steps, including sample weighing and distillation operation points. Standardized titration process and end point judgment. According to this standard, the volatile alkali content in caprolactone amide can be accurately determined, providing key data for product quality control and production process optimization.
