Cobalt Chloride powder Usage and Synthesis.

Cobalt chloride is a chemical substance that has a variety of uses. In instrument manufacture, it is used in the production of barometers, hydrometers, wet and dry indicators, and so on. In the ceramics industry, it is used as a coloring agent. In the paint industry, it is used in the manufacture of paint drying agents.

In the livestock industry, it is used to prepare compound feed. In the brewing industry, it is used as a beer foam stabilizer. In the defense industry, it is used to manufacture gas masks.

In chemical reactions, it is used as a catalyst and oxidizer. In addition, cobalt chloride is also used in the manufacture of invisible ink, cobalt chloride test paper, color-changing silica gel and so on.

Uses of Cobalt Chloride powder.

Cobalt chloride is mainly used in the production of cobalt oxide and cobalt metal, as alloy materials for electronic materials, a small amount of instrumentation used in the production of barometers, hydrometers, wet and dry indicators. It is used as coloring agent in ceramic industry. It is used as paint drying agent in paint industry. It is used to configure compound feed in animal husbandry industry.

Used as beer foam stabilizer in brewing industry. Used in the defense industry to manufacture gas masks. Used as catalyst in chemical reaction. Fractionation chemistry for droplet analysis of zinc, haploid breeding, in addition, also used in the manufacture of invisible ink, cobalt chloride test paper (in the dry is blue, when wet to pink), color-changing silica gel and so on. Also used as an absorbent for ammonia.

Preparation of Cobalt Chloride powder.

Cobalt chloride is mainly prepared by metal cobalt method and cobalt-containing waste method. Metal cobalt method is obtained by reacting metal cobalt with hydrochloric acid and nitric acid, through purification, precipitation, filtration, evaporation, crystallization and separation.

Cobalt-containing waste method is to react cobalt-containing waste with hydrochloric acid and sulfuric acid, transformed with sodium sulfide and obtained by washing, oxidizing, separating, acidifying and washing, refining and concentrating.

A preparation method of superior pure cobalt chloride has the following steps:

(1) metal cobalt and hydrochloric acid reaction: metal cobalt placed in a glass beaker, and add hydrochloric acid moved to the furnace for heating reaction, reaction temperature control at 70 ℃ -75 ℃, and the appropriate amount of addition of nitric acid, to promote the dissolution of metal cobalt completely, the amount of addition to control in the amount of hydrochloric acid 15-20%, to be completely dissolved in metal cobalt, the temperature of the furnace will be raised to the solution boiled, add hydrochloric acid, evaporation of the appearance of white gas Until, stop heating, stop adding hydrochloric acid, cobalt chloride solution;

(2) in addition to impurities: step (1) of the cobalt chloride solution to add hydrogen peroxide oxidation to remove iron, and this solution with ammonia to pH 8-9, to ensure that the precipitation of iron hydroxide is complete, stand still for 3-5 hours, filtration, to get the solution;

(3) the production of superior pure cobalt chloride: the solution obtained in step (2) is poured into a glass beaker, hydrochloric acid to adjust pH3-3.5, concentration, concentration temperature 170-190 ℃, after concentration to 38-40 ゜ Be, stop heating, cooling crystallization, centrifugal separation to obtain superior pure cobalt chloride crystals.

Product method of Bulk Cobalt Chloride powder.

Action of cobalt chloride hexahydrate with sulfoxide chloride. 20g of finely ground CoCl2-6H2O into a round-bottomed flask, add 50mL of newly distilled sulfoxide chloride at room temperature, immediately SO2 and HCl release, such as foaming stops, a reflux condenser tube is installed on the flask to reflux this mixture for 1 to 2h, and then the reflux tube is modified to make it into a distillation device, and blowing dry nitrogen under reduced pressure will be the excess of the sulfoxide chloride was distilled out.

The flask containing the product is immediately transferred to a vacuum desiccator containing potassium hydroxide and stored therein for at least 12h to remove the residual sulfoxide. Finally, the product is transferred to a suitable container in a dry operating box and sealed.
