GB/T 2384-2015 is a general method standard for determining the melting point range of dyestuff intermediates. It is suitable for all kinds of dyestuff intermediate products. The standard stipulates the use of instruments such as Melting Point Meter to carefully observe the physical state changes of the sample by slowly heating it. Clarify the requirements for sample preparation and filling, and standardize the operation procedures such as heating rate and observation Frequency. Determine the melting point range based on the temperature at which the sample begins to show signs of melting and the temperature at which it is completely melted. According to this standard, the melting point range of dyestuff intermediates can be accurately determined, providing key data for the quality control, production process optimization and application of dyestuff intermediates, and ensuring the mass and performance of dyestuff products.
