10294-31-2 Usage
Chemical Properties
yellowish to greenish yellow powder(s); decomposes slowly at ordinary temp, rapidly at elevated temp [MER06]
Uses
Gold(I) iodide is employed in the synthesis of chemicals.
General Description
AuI can be prepared by adding KI in an acidic solution of HAuCl4.
Purification Methods
It has been prepared by heating gold and iodine in a tube at 120o for 4 months. Since it decomposes to Au and I2 in the presence of UV light and heat, then the main impurity is Au. The salt is therefore purified by heating at 120o with I2 for several weeks. The crystals should be kept dry and in a cool place in the dark. [Weiss & Weiss Z Naturforsch 11B 604 1956.]
Check Digit Verification of cas no
The CAS Registry Mumber 10294-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,9 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10294-31:
(7*1)+(6*0)+(5*2)+(4*9)+(3*4)+(2*3)+(1*1)=72
72 % 10 = 2
So 10294-31-2 is a valid CAS Registry Number.

Gold(I) halides have been obtained from Au2Cl6: a) with cyclohexene as halogen acceptor (AuCl); b) by halide exchange with i-Pr-Br, followed by treatment with cyclohexene at low temperature (AuBr); c) by halide exchange with i-Pr-I at room temperature (AuI).Carbonylation of AuBr in dichloromethane or treatment of Au2Br6 with CO and cyclohexene in 1,2-dibromoethane yielded AuBr(CO), characterized by IR and 13C NMR spectra in solution, the latter at low temperature
