101707-17-9 Usage
Chemical Properties
Polyaluminum chloride (PAC) is white, light gray, light yellow or brown crystals or powders. The color varies with the production process and raw materials. It is slightly acidic. After dilution with water, aluminum hydroxide precipitates. In the hydrolysis process, physical and chemical processes such as electrochemistry, coagulation, adsorption and precipitation are accompanied, so as to achieve the purpose of water purification.
Uses
Polyaluminum chloride has the advantages of high adsorption activity, wide range of pH value, no need for coagulation aids and no influence of water temperature, etc. It is widely used in water purification treatment of domestic water, industrial water, etc.
Preparation
In the mixed solution of aluminum sulfate and aluminum trichloride, lime and limestone are added to make sulfate ions and calcium form insoluble calcium sulfate precipitation, which is separated from the mixed solution to increase the aluminum-chloride equivalent ratio, thereby obtaining a certain aggregate polyaluminum chloride.
Check Digit Verification of cas no
The CAS Registry Mumber 101707-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,7,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 101707-17:
(8*1)+(7*0)+(6*1)+(5*7)+(4*0)+(3*7)+(2*1)+(1*7)=79
79 % 10 = 9
So 101707-17-9 is a valid CAS Registry Number.
