7784-26-1 Usage

Chemical Properties

white crystals or powder

Uses

Ammonium aluminum sulfate dodecahydrate may be used in the preparation of alum (Al(OH)3) gel and monodispersed yttrium aluminum garnet (YAG) powder.

General Description

Ammonium aluminum sulfate dodecahydrate, commonly called as ammonium alum, is widely used in the water purification, cosmetic formulation, fertilizers and food preservation. Its thermal decomposition has been studied. It has high latent heat of 251kJkg-1 with a potential use in the heating system. Its utility as a flame-retardant for cotton fabric has been studied.

Purification Methods

Crystallise it from hot H2O and cool in ice. When the melt is heated, it loses NH3 and H2SO4, and gives pure alumina at red heat. Solubility (%) in H2O is 3.9 (0o), 15.0 (20o) and 135 (100o).

Check Digit Verification of cas no

The CAS Registry Mumber 7784-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7784-26:
(6*7)+(5*7)+(4*8)+(3*4)+(2*2)+(1*6)=131
131 % 10 = 1
So 7784-26-1 is a valid CAS Registry Number.
