28064-14-4 Usage
Uses
Re2O7 acts as a catalyst in the heteroacylative dimerization of THF.Adhesives, structural and electrical laminates and coatings and castings for high temperature service.
General Description
Poly [(phenyl glycidyl ether)-co-formaldehyde] (Re2O7) is a strong oxidant and a highly selective Lewis acid catalyst. The structure is constituted of strongly distorted ReO4 octahedra and nearly regular ReO4 tetrahedra which are connected through corners to form polymeric double layers in the ac plane.
Check Digit Verification of cas no
The CAS Registry Mumber 28064-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,6 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28064-14:
(7*2)+(6*8)+(5*0)+(4*6)+(3*4)+(2*1)+(1*4)=104
104 % 10 = 4
So 28064-14-4 is a valid CAS Registry Number.

, (2008/06/13)
Titled materials and their preparation. The materials contain a moiety such as, for example, 4-oxy-3,5-dimethyl-2,6-dibromobenzyl which can impart a high degree of thermal and hydrolytic stability to the materials, for example, epoxy thermosets such as in electronic encapsulations. For example, when used in electronic encapsulation formulations, these materials can provide a substantial increase in electronic device reliability. Their preparation involves an alkylation of an aromatic ring, for example, such as a Friedel-Crafts alkylation with 4-bromomethyl-3,5-dibromo-2,6-dimethylphenol or with 4-hydroxymethyl-3,5-dibromo-2,6-dimethylphenol.
