Sodium tetraphenylborate 143-66-8

White crystal. The impure substance is pink to yellow, and the spoiled product has the odor of aniline. Therefore, the newly prepared sodium tetraphenylboron should be used in analytical chemistry. [2] soluble in water, ethanol, methanol, ethanol and acetone, slightly soluble in benzene and chloroform, almost insoluble in petroleum ether. Slightly hygroscopic, decomposes gradually in aqueous solution and becomes turbid (solid is more stable). Aqueous solution pH adjustment to about 5, can be preserved in the room temperature (45 ℃ save 5 d and not bad).

Operation handling and storage editing

Notes for operation: operators should receive special training and strictly abide by the operation rules. Operation and disposal shall be carried out in a place with local ventilation or comprehensive ventilation and ventilation facilities. Avoid eye to skin contact and avoid inhaling vapor. Keep away from fire and heat. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. If canning is needed, the flow rate should be controlled, and there is a grounding device to prevent the accumulation of static electricity. Avoid contact with prohibited compounds such as oxidants. Handle with care to prevent damage of package and container. Empty containers may contain residues of harmful substances. Wash your hands after use and do not eat or drink in the workplace. Equipped with the corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment.

Storage precautions: store in a cool and ventilated warehouse. Library temperature should not be more than 37 ° C. Should be stored separately from oxidant and edible chemicals, avoid by all means mixed storage. Keep container sealed. Keep away from fire and heat. The storeroom must be equipped with lightning protection equipment. The exhaust air system shall be provided with grounding device for conducting and removing static electricity. Explosion-proof lighting and ventilation are adopted. Do not use spark-prone equipment or tools. The storage area shall be provided with emergency leakage treatment equipment and suitable storage materials.
