Bis(trimethylsilyl) diethyl silicate, also known as bis(trimethylsilyl) ethoxysilane, is a colorless liquid chemical compound with the molecular formula C8H22O2Si3. It is a derivative of silicate, where two trimethylsilyl groups are attached to a central silicon atom, and two ethoxy groups are bonded to the silicon as well. bis(trimethylsilyl) diethyl silicate is widely used in the synthesis of various organosilicon compounds, as a coupling agent in the production of composite materials, and as a silylating agent in organic synthesis. It is also employed as a reagent in the preparation of silyl ethers and as a stabilizer for certain polymers. Due to its reactivity and versatility, bis(trimethylsilyl) diethyl silicate plays a significant role in the field of organosilicon chemistry.

3555-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3555-45-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,5 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3555-45:
(6*3)+(5*5)+(4*5)+(3*5)+(2*4)+(1*5)=91
91 % 10 = 1
So 3555-45-1 is a valid CAS Registry Number.

Recovery of trimethylchlorosilane from its azeotropic mixture with SiCl4

Voronkov,Baryshok,Kuznetsova

, p. 2091 - 2094 (2007/10/03)

Reaction of tetraethoxysilane with the azeotropic mixture Me3SiCl-SiCl4 in the presence of certain cyclic (tetrahydrofuran, dioxane) and acyclic (diethyl ether) ethers, ethanol, or dimethylformamide was studied with the aim of SiMe3Cl recovery.

Treatment of Tetraalkoxysilanes with Amberlyst 15 Cation-Exchange Resin in Presence of Hexamethyldisiloxane

Hasegawa, Isao,Sakka, Sumio

, p. 4313 - 4316 (2007/10/02)

Tetraalkoxysilanes were treated with Amberlyst 15 cation-exchange resin in hexamethyldisiloxane at 40 deg C in order to substitute the trimethylsilyl group for the alkyl group in a tetraalkoxysilane partially.Tetramethoxy-, ethoxy-, propoxy-, and butoxysilanes were used for the experiments.After the treatment, SiO4R(4-n)Xn (1 /= n /= 4, R = CH3, C2H5, n-C3H7, and n-C4H9, X = Si(CH3)3) were detected by gas chromatography-mass spectrometry.The degree of trimethylsilylation of tetraalkoxysilane changed with the molar ratio of hexamethyldisiloxane to tetraalkoxysilane and quantities of the reaction products in the system depended mainly on the ratio.

Preparation of Alkyl-substituted Partial Trimethylsilyl Silicates from Olivine

Kuroda, Kazuyuki,Koike, Tetsuhiro,Kato, Chuzo

, p. 1957 - 1960 (2007/10/02)

The direct trimethylsilylation reaction of olivine has yielded partial trimethylsilyl derivatives of ortho- and di-silicates whose unsilylated silanol groups have been esterified with the alcohol used as the organic solvent in the trimethylsilylating reagent.Gas chromatographic-mass spectroscopic measurements indicate the presence of the tri-, di-, and mono-alkyl-substituted trimethylsilyl derivatives of monosilicic acid in addition to the fully silylated monomeric derivative .Dimeric derivatives have also been detected which contain both the completely trimethylsilylated derivative and alcohol-esterified derivatives .The ratio of the esterified products varies with the volume of alcohol or water in the silylating reagent as well as the reaction time.
