General Description
Bis(trimethylsiloxy)ethylsilane, also known by its chemical formula (C2H5)H2Si(OSi(CH3)3)2, is an organosilicon compound that's used widely in the field of chemistry. This clear, colorless liquid has applications in various industries due to its unique properties. It is often employed as a precursor to other silicon-containing compounds, including those used in surface modifications, creation of silicone materials, and semiconductor fabrication. In addition, it plays an important role in the production of silicone resins and rubbers, contributing to their thermal stability and flexibility. Despite many benefits, it must be handled with care as it poses risks such as skin and eye irritation, and is considered harmful if ingested or inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 7543-58-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,4 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7543-58:
(6*7)+(5*5)+(4*4)+(3*3)+(2*5)+(1*8)=110
110 % 10 = 0
So 7543-58-0 is a valid CAS Registry Number.

FEATURES OF INFLUENCE OF HCl ON HYDROLYTIC COPOLYCONDENSATION OF BIFUNCTIONAL ORGANOCHLOROSILANES WITH TRIMETHYLCHLOROSILANE

The hydrogen chloride that is formed in the hydrolytic copolycondensation of R'RSiCl2 with Me3SiCl affects the composition of the reaction products only at cocentrations above 30-35percent, where it is responsible for splitting out the terminal trimethylsiloxy group.The stability of the terminal groups increases with increasing size of the substituents on the silicon atom in the R'RSiCl2.The total yield of Me3SiO(R'RSiO)mSiMe3 with m = 1-4 also increases with increasing size of the substituents on the silicon atom in the R'RSiCl2.The total yield of p with p = 3-5 increases with decreasing tendency of the R'RSiCl2 to form rings by hydrolytic polycondensation, and with increasing sensitivity of the terminal trimethylsiloxy group in the cocondensation products to the action of HCl and its activity with respect to the siloxane bond.
