The crystallization point detection of benzene is a characteristic index of purity testing of general industrial products.
In the low temperature cooling process, the pure liquid may appear too cold state, namely when at or below the temperature of crystallization point, the material is still in a liquid state without precipitation crystallization to coagulation state, the main reason is due to the static in the liquid, no enough seed formation, although reach even below the crystallization temperature at this moment, but not in crystallization. When there is proper stirring in the system, with the cooling process, there are enough seed crystals to promote the formation of crystallization.
Therefore, when determining the crystallization point of benzene, it is clearly stated in the operation process that the cooling operation is carried out and the liquid of benzene sample is stirred appropriately at the same time. Without stirring, the measurements will be low and abnormal temperature increases may occur during the measurement process.
SH406B automatic benzene crystallization point measurement instrument applicable to the standard GB/T3145-1982 benzene crystallization point determination, GB/T 3069.2-2005 naphthalene crystallization point determination, GB/T 3710-2009 industrial phenol, phenol crystallization point determination, GB/T7533-1993-2005 Determination of crystallization point of organic chemical products, GB/T618-2006 determination of crystallization point of chemical reagents GB/T1663-2001 Plasticizer crystallization point determination. (Benzene crystallizing point instrument, phenol crystallizing point instrument, phenol crystallizing point instrument, freezing point instrument, plasticizer crystallizing point instrument)
Features of the instrument: The embedded system design, the whole process of automatic testing; Adopt imported PT100 sensor and imported temperature control system. Color touch screen; The test results can be stored; Historical data can be viewed; The printed results on the instrument, mechanical automatic stirring, the experimental results can be exported through the U disk, stored in the computer can be tested and compared for many times.
