7783-59-7 Usage
Chemical Properties
Like all the lead tetrahalides, lead tetrafluoride [CAS: 7783-59-7], PbF4, is very reactive. It is relatively the most stable halide, however. PbF4 is a white crystalline powder, which is highly moisture sensitive, turning yellowish brown in moist air owing to hydrolysis. It should be handled in a dry box or under an atmosphere of dry nitrogen.
Physical properties
White tetragonal crystals; density 6.7 g/cm3; melts at about 600°C; hydrolyzes readily when exposed to moist air.
Uses
Has been proposed as a fluorinating agent for hydrocarbons.
Preparation
The tetrafluoride is obtained by fluorination of lead difluoride. The method involves passing a mixture of fluorine and nitrogen or carbon dioxide over lead difluoride at 300°C.
PbF2 + F2 → PbF4
Check Digit Verification of cas no
The CAS Registry Mumber 7783-59-7 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 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7783-59:
(6*7)+(5*7)+(4*8)+(3*3)+(2*5)+(1*9)=137
137 % 10 = 7
So 7783-59-7 is a valid CAS Registry Number.
