Chemical Properties

Methyltriacetoxysilane (MTAC) is a clear to yellowish liquid with acrid odor of acetic acid (vinegar). It hydrolyzes in the presence of moisture (acetic acid is released) to form silanols, which can react with themselves to pro-duce siloxanes or bind to inorganic substrates.

Flammability and Explosibility

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 4253-34-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4253-34:
(6*4)+(5*2)+(4*5)+(3*3)+(2*3)+(1*4)=73
73 % 10 = 3
So 4253-34-3 is a valid CAS Registry Number.

Silicone-barium titanate composites with increased electromechanical sensitivity. the effects of the filler morphology

Bele,Cazacu,Stiubianu,Vlad

, p. 58522 - 58529 (2014)

A high molecular weight polydimethylsiloxane-α,ω-diol, synthesized in the lab, was used as a matrix for nanocomposites. Barium titanate nanoparticles, either cubic or nanorods, were obtained by a hydrothermal procedure and used as a filler. In order to ensure a good compatibility with the matrix, the filler was surface treated with a commercial surfactant. A highly reactive trifunctional silane was used as crosslinking agent in the presence of organometallic catalyst. Two other samples, the first consisting of pure crosslinked polydimethylsiloxane and the second being the polymer matrix filled with commercial barium titanate, were prepared and used as references to evaluate the influence of the presence of barium titanate nanoparticles and their shape on some characteristics of the resulting crosslinked composites: morphology, thermal behavior, moisture sorption, mechanical and dielectric characteristics. The electromechanical sensitivity and energy output were calculated on the basis of appropriate experimental data in order to estimate the potential of the composites for future electromechanical applications.

Preparation of acyloxysilanes

-

, (2008/06/13)

Acyloxysilanes are prepared by the anhydrous reaction of stoichiometric amounts of a carboxylic acid with a mixture of a halosilane and a silazane in an aprotic solvent, such as diethyl ether, acetonitrile, tetrahydrofuran or toluene, in an inert gas atmosphere. In a preferred embodiment the silazane is prepared in situ by the reaction of the corresponding halosilane and ammonia. No catalyst is necessary and the reaction preferably is performed at a temperature of -5° C. to 45° C.

Process for preparing triacetoxysilanes from tris(amino)silanes

-

, (2008/06/13)

Triacetoxysilanes are prepared by adding a tris(amino)silane to acetic anhydride and maintaining the reaction mix at a temperature no greater than about 50° C.
