Description
Aluminum citrate is a chemical compound formed by the reaction between aluminum salt and citric acid, resulting in a white powder or scaly substance. It is known for its complex formation properties and has various applications across different industries.
Uses
Used in Enhanced Oil Recovery:
Aluminum citrate is used as a crosslinking agent for polymers such as carboxymethylcellulose (CMC) or partially hydrolyzed polyacrylamide in enhanced oil recovery processes. The crosslinking with aluminum citrate helps in blocking highly permeable zones, allowing for the recovery of oils that would be otherwise inaccessible through conventional methods.
Used in Subterranean Formations:
In the context of subterranean formations, aluminum citrate is used as a crosslinking agent for polymeric materials to reduce the permeability of the formations to water. This application aids in managing the flow of water and improving the efficiency of various industrial processes.
Used in Cosmetic Products:
Aluminum citrate is used as an active ingredient in cosmetic products with anti-perspiration effects. Its properties contribute to the development of formulations that help control perspiration and provide a more comfortable experience for users.
Used in Synthesis of Aluminum Nitride:
Aluminum citrate has been utilized as a precursor in the synthesis of aluminum nitride, a material with significant applications in various industries due to its unique properties, such as high thermal conductivity and electrical insulation.
Synthesis
Aluminum citrate can be manufactured with aluminum chloride and citric acid as the starting materials. The pH of the mixture can be adjusted with either ammonium hydroxide or sodium hydroxide to obtain aluminum citrate.1,2
Toxicological studies
Aluminum is established as neurotoxicant. The uptake of aluminum in the form of aluminum citrate is 50 times than that in aluminum hydroxide form.6

Check Digit Verification of cas no
The CAS Registry Mumber 31142-56-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,4 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31142-56:
(7*3)+(6*1)+(5*1)+(4*4)+(3*2)+(2*5)+(1*6)=70
70 % 10 = 0
So 31142-56-0 is a valid CAS Registry Number.
