NOVELTY - Purifying chloroacetyl chloride, comprises e.g. heating chloroacetyl chloride crude product and activated carbon in a container, insulating it and stirring, then keeping it over night, separating and discharging activated carbon sediment to obtain chloroacetyl chloride clear liquid, placing the clear liquid in a flask, adding zinc particles and refluxing, cooling obtained liquid over night, separating sediment and unreacted zinc particle and extracting a clear liquid, adding the clear liquid into a rectifying device, then adding glacial acetic acid and rectifying for three times separately.    USE - The purified chloroacetyl chloride is useful in microelectronics high-tech industry for manufacturing semiconductor integrated circuit and crystalline-silicon solar cell.    ADVANTAGE - The method: utilizes easily available raw material; has simple physical process and no side product; and utilizes quartz rectification device, which reduces contamination of finished product caused by impurities of the device, and thus it ensures product purity.    DETAILED DESCRIPTION - Purifying chloroacetyl chloride, comprises (i) adding chloroacetyl chloride crude product and activated carbon into a container and heating to 70-80 degrees C with stirring, insulating it for 1.5-2.5 hours, and going on stirring for 3-5 hours, then allowing to stand over night, separating and discharging activated carbon sediment to obtain chloroacetyl chloride clear liquid, then (ii) placing the chloroacetyl chloride clear liquid in a flask, adding zinc particles, then mounting a reflux device, heating to 85-100 degrees C and refluxing for 2 hours, allowing to stand obtained liquid and cooling over night, separating sediment and unreacted zinc particle, and extracting a clear liquid, and (iii) filtering the clear liquid, adding the clear liquid into a rectifying device, then adding glacial acetic acid, rectifying for first time and collecting fraction at 102-106 degrees C, then (iv) adding the obtained rectified fraction into another rectifying device, rectifying for second time and collecting fraction at 104-106 degrees C, and (v) again adding the obtained fraction into another rectifying device, rectifying for third time, and mounting a desiccant containing drying agent on side part of the rectifying device to collect fraction at 105-106 degrees C.
