liquid. Fumes in humid air.
General Description
Ethylphenyldichlorosilane is a colorless liquid with a pungent odor. Ethylphenyldichlorosilane is decomposed by water to hydrochloric acid with evolution of heat. Ethylphenyldichlorosilane is corrosive to metals and tissue.
Air & Water Reactions
Reacts vigorously with water to form hydrogen chloride(hydrochloric acid)
Reactivity Profile
Chlorosilanes, such as Ethylphenyldichlorosilane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. Special Hazards of Combustion Products: Toxic hydrogen chloride and phosgene fumes may be formed.
Health Hazard
Inhalation irritates nose and throat. Contact with liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach.
Safety Profile
Poison by ingestion and
inhalation. A poison irritant to skin, eyes,
and mucous membranes. Corrosive. Will
react with water or steam to produce toxic
and corrosive fumes. Can react with
oxidizing materials. When heated to
decomposition it emits toxic fumes of Cl
and phenol. See also CHLOROSILANES.
Potential Exposure
Used in the manufacture of silicone
polymers
Shipping
UN2435 Ethylphenyldichlorosilane, Hazard
class: 8; Labels: 8-Corrosive material.
Incompatibilities
A strong reducing agent. Incompatible
with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from
alkaline materials, strong bases, strong acids, oxoacids, and
epoxides. Chlorosilanes react vigorously with bases and
both organic and inorganic acids generating toxic and/or
flammable gases. Chlorosilanes react with water, moist air,
or steam to produce heat and toxic, corrosive fumes of
hydrogen chloride. They may also produce flammable gaseous hydrogen. Attacks human tissue and metals in the
presence of moisture
Check Digit Verification of cas no
The CAS Registry Mumber 1125-27-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1125-27:
(6*1)+(5*1)+(4*2)+(3*5)+(2*2)+(1*7)=45
45 % 10 = 5
So 1125-27-5 is a valid CAS Registry Number.

Reaction of chloro(ethyl)silanes with chloro(phenyl)silanes in the presence of aluminum chloride. Synthesis of chloro(ethyl)(phenyl)silanes

, p. 595 - 599 (2015)
Abstract Substituent exchange at the silicon atom between chloro(phenyl)silanes (PhSiCl3, MePhSiCl2, Ph2SiCl2) and chloro(ethyl)silanes (EtSiCl3, Et2SiCl2, Et3SiCl, Et4Si) in the presence of aluminum chloride has been studied. The examined compounds, except for PhSiCl3 and Et4Si, react fairly readily to give chloro(ethyl)-(phenyl)silanes in up to 48-52% yield. A probable mechanism has been proposed.

The transient absorption of radical cations of a variety of substituted polysilanes is discussed quantitatively in terms of the molar extinction coefficient and oscillator strength by nanosecond pulse radiolysis. Oxygen-saturated polysilane solutions in benzene exhibit a strong transient absorption band ascribed to the polysilane radical cation. The transient species react with N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD) to produce TMPD radical cations. On the basis of the molar extinction coefficient of the TMPD radical cation, the molar extinction coefficients for the radical cations of polysilanes are found to increase in the range 3.3 × 104 to 2.0 × 105 M-1 cm -1 with increasing polymer segment length. The stepwise increase in the total oscillator strength with an increase in the number of phenyl rings directly bonded to the Si skeleton suggests the delocalization of the positive polaron state and/or the SOMO state over the phenyl rings, indicating the importance of phenyl rings in intermolecular hole transfer processes.

Macrocyclic polyether "crown" compounds of the formula EQU1 WHEREIN T is a C2 -C3 alkylene, A is EQU2 R being H or C1 -C18 alkyl, R2 and R3 being independently C1 -C18 alkyl, C2 -C4 alkenyl, or C6 -C14 aryl; Q and Z are independently 1,2-arylene (or saturated derivatives thereof) or substituted 1,2-arylene (or saturated derivatives thereof); a is 0, 1, 2, or 3; b is an integer from 3 to 20; y is 1 or zero; x1, x2, x3, and x4 are integers independently selected to give a 15-60 atom ring. Such crown compounds are generally useful in the formation of complexes with ionic metal compounds, thus making it possible to use certain chemical reagents in media wherein they are normally insoluble.
