Inspection Process
Appearance and properties inspection
Observe the sample visually in a well-lit area. Pure 1-bromo-3-chloropropane should be a colorless and transparent liquid. If it is yellow, turbid, or has precipitation and stratification, it means that the product quality is poor, and impurities may be mixed in or deteriorate.
Purity detection
Gas chromatography (GC): dilute the sample with a suitable organic solvent and inject it into a gas chromatograph that has been debugged and calibrated and has a stable carrier gas. With the help of standard reference, the target is locked according to the peak time, and the purity is calculated according to the peak area. The proportion of 1-bromo-3-chloropropane and its impurity content can be accurately determined.
Stability detection
Thermal stability: Seal the sample in a pressure-resistant glass container and place it in an oven with a set gradient temperature (such as 50℃, 80℃, 100℃). Check the appearance regularly to see if there is any volatile decomposition, and then compare the components before and after chemical analysis to judge the thermal stability.
Light stability: Leave the sample open or place it in a light-transmitting container and place it in a light box to simulate sunlight or ultraviolet light. Observe changes in color and properties, record the time of deterioration, and understand the light stability.
