Sulfur (cas 9035 99 8 or 9035-99-8) is an important variety of inorganic pesticides. The chemical property is relatively active, can with oxygen, hydrogen, halogen (except iodine), metal and most other elements, generate ionic compounds or covalent compounds. The commodity is yellow solid or powder, has obvious odour and can be volatile. Sulfur aqueous suspension is slightly acidic, insoluble in water, and react with alkali to generate polysulfide. Sulphur burns with a green flame, accompanied by the combustion of sulphur dioxide gas. The production of sulfur is often processed into a suspending agent for the control of pests and diseases, it is safe for humans and animals, and not easy to make the crops produce pests. Do you know how sulphur is refined?
We will introduce two refining methods here. The first simple purification method of sulphur, the first use of carbon disulphide to dissolve the sulphur ore and filter out the impurities, and then the carbon disulphide and dissolved in which the sulphur is separated that is to get the purified sulphur, the separation of carbon disulphide and sulphur method: dissolved sulphur of carbon disulphide solution sprayed to the temperature of 70-75 ° C hot water can be achieved the separation of the second simple purification method of sulphur The second method of simple purification of sulphur, first use carbon disulphide to dissolve the sulphur ore and filter out the impurities, and then make the carbon disulphide and the sulphur dissolved therein to separate that is to get the purified sulphur The method of separating the carbon disulphide and the sulphur is as follows: Spray the carbon disulphide solution with the sulphur dissolved therein into hot water at a temperature of 70-75°C to achieve the separation of both of them to get the sulphur (hd7720). Now do you understand the process?
