16712-20-2 - Reference Information
| introduction | lithium chloride is white and a regular crystal with NaC1 type face-centered lattice (a = 0.513nm). Melting point 605 ℃, boiling point 136 ℃. Very hygroscopic, soluble in methanol, ethanol, pyridine, ether, acetone, slightly soluble in liquid ammonia. Lithium chloride monohydrate is a compound composed of lithium chloride and water. |
| Use | Due to the controlled nuclear fusion reaction of lithium chloride and its derivatives, aluminum-lithium alloys, lithium-ion batteries, nonlinear optical materials in optical communications, etc. The demand for raw material lithium chloride has increased significantly, and this trend is becoming more and more obvious, which makes the production of lithium chloride show unprecedented good prospects. Lithium chloride monohydrate is a compound composed of lithium chloride and water. |
| production method | 1. gradually add pure lithium carbonate to hydrochloric acid to make lithium carbonate excessive. After the reaction is completed, filter, evaporate the filtrate until most of the crystals are precipitated, and then cool and filter to obtain pure lithium chloride. 2. Preparation method Add water to industrial lithium carbonate, heat and stir, filter while hot, spin dry, and repeat twice to remove most of the K Na plasma. The soaked raw material lithium carbonate is slowly added to hydrochloric acid with a relative density of 1.19, and the reaction is carried out: after the reaction, a small amount of undissolved lithium carbonate should be left, and the pH of the solution at this time is 6~7. Filter out the insoluble matter, add hydrochloric acid to the filtrate to pH = 3-then add an appropriate amount of barium chloride, let it stand, after the barium sulfate is completely precipitated, add lithium hydroxide to the solution = 1 2, add an appropriate amount of oxalic acid, precipitate Ca 2 Mg 2 ions, filter, evaporate the filtrate until a large amount of crystallization is precipitated, cool with ice water, continue crystallization, and drain the reagent lithium chloride monohydrate is obtained. |
