Lithium perchloride - Preparation Method
Open Data Verified Data
double decomposition method: the sodium perchlorate solution is added into the reactor, and anhydrous lithium chloride is added to heat and carry out double decomposition reaction to generate lithium perchlorate and sodium chloride. The sodium chloride is removed by filtration, the filtrate is evaporated and concentrated, and the crystal is cooled, after further purification, filtration, the filtrate was cooled and crystallized, centrifuged and dried to obtain lithium perchlorate.

Package shall be marked with "oxidant. Oxidant. Risk code: GB 5.1 class 51020. UNNO.1481;IMDG code 5.1, P. A., Class 2. Should be stored in a cool, ventilated warehouse. Keep away from fire and heat source. The packaging must be sealed and free from moisture. It should be stored separately from easy (possibly) combustible materials and active metal powder, and mixed storage should not be avoided. During transport to prevent rain and exposure. Pay attention to moisture. When loading and unloading, it is necessary to take it lightly, and collision or friction is strictly prohibited. In case of fire, fog water and sand should be used for fire suppression. Toxicity and protection: the goods on the eyes, skin, mucous membranes and upper respiratory tract irritation. High concentration exposure, serious damage to the mucosa, upper respiratory tract, eyes and skin. Poisoning showed burning sensation, Cough, wheezing, shortness of breath, laryngitis, Head Pain, Nausea and Vomit. If you accidentally splash into the eyes or splash on the skin, you should immediately rinse with a large amount of water, and the severe cases should be sent to the hospital for treatment. If accidentally eating, should immediately emetic, and water gargle, to drink milk or egg white. The patient visited hospital. Production personnel should wear work clothes, wear protective masks or gas masks, latex gloves, wear long rubber boots and other labor protection articles to protect respiratory organs, eyes and skin. Production equipment should be closed, workshop ventilation should be good. Wash your work clothes and shower after work.

| lithium battery | lithium battery is a chemical battery that uses lithium as the negative active material. Lithium perchlorate or lithium bromide is commonly used as the electrolyte, the standard electrode potential of lithium is the most negative (-3.03V), with the lightest specific gravity and the highest reactive activity in the metal. Therefore, the electromotive force and specific energy of lithium battery are very high, which is an important high-energy battery, the effective electric energy per unit weight is 10 to 12 times that of the lead-acid battery, and the discharge current is very stable. The positive active materials of lithium batteries include inorganic electrode materials such as oxides, sulfides, halides, halogens, oxo-salts, etc., such as manganese dioxide, sulfur dioxide, copper sulfide, silver chromate, polyfluorocarbon, thionyl chloride, iodine, etc; electronically conductive polymers, such as polyacetylene, polypyrrole, polythiophene, polycarbazole and the like, can also be used as positive electrode materials, also known as polymer batteries. The electrolytes of lithium batteries are non-aqueous solutions, solids, and molten salts. The non-aqueous electrolyte is composed of organic solvents or non-aqueous inorganic solvents, and the organic solvents used are mainly propylene carbonate, dimethyl propionamide, acetonitrile, γ-butyrolactone, etc. The non-aqueous inorganic solvent is thionyl chloride, liquid sulfur dioxide, etc. Inorganic salts include lithium perchlorate, lithium aluminum chloride, lithium fluoroborate, and lithium bromide. Due to the immediate intense reaction of lithium and water contact, not only the electrolyte can not be used in aqueous solution, and all materials and parts are strictly dehydrated, and reliable sealing. Lithium battery for primary battery, products have a variety of shapes and specifications, such as cylindrical, button-type, plug-type, etc., in communication, camera, electronic watch, calculator, pacemakers and other electronic devices are widely used. This kind of battery is characterized by high voltage, high current density, can be used at high temperature, no leakage of liquid, small self-discharge, long service life, etc., has recently been developed for high energy storage battery in the flash, the negative electrode is lithium, the positive electrode is lithium dioxide, and the electrolyte is prepared by dissolving lithium perchlorate in propylene carbonate and having a concentration of 0.5 to 1.0 mol/l. |
| conductive adhesive | conductive adhesive is used in medical devices such as electrocardiogram, electroencephalogram and low frequency therapeutic apparatus, when the electrode is adhered to the skin, the adhesive can fix the electrode and the skin, and can also be conductive. This adhesive is prepared by adding lithium perchlorate to the polymer material, the specific resistance of this adhesive is 104 to 106 Ω · cm. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water at different temperatures (℃): 42.7g/0 ℃;49g/10 ℃;56.1g/20 ℃;63.6g/30 ℃;72.3g/40 ℃; 92.3g/60 ℃;128g/80 ℃;151G/90 ℃ |
| toxicity | see barium perchlorate. |
| Use | for solid rocket propellants, for lithium battery electrolyte components, for catalysts and oxidants. used as rocket jet fuel, lithium battery raw materials, etc. An effective protein denaturant, used as an oxidant; Lithium battery electrolyte. |
| production method | double decomposition method the sodium perchlorate solution is added to the reactor, and heated with Anhydrous Lithium chloride for double decomposition reaction, lithium perchlorate and sodium chloride are generated, sodium chloride is removed by filtration, the filtrate is concentrated by evaporation, cooled and crystallized, and then refined. After filtration, the filtrate is cooled and crystallized, centrifuged and dried to obtain lithium perchlorate. Its NaC1O4 LiCl → LiClO4 NaCl |
