MERCURY COMPOUNDS, ORGANIC.
When heated to decomposition it emits very
toxic fumes of Cland Hg.
Potential Exposure
This chemical is used in manufacture of
coatings, resins, and lacquers. Widely known as “Plexiglass”
(in the polymer form), ethyl methacrylate is used to make
polymers, which in turn are used for building, automotive,
aerospace, and furniture industries. It is also used by dentists
as dental plates, artificial teeth, and orthopedic cement.
Shipping
UN2277 Ethyl methacrylate, stabilized, Hazard
Class: 3; Labels: 3-Flammable liquid
Purification Methods
Mercuric chloride can be removed by suspending ethylmercuric chloride in hot distilled water, filtering with suction onto a sintered-glass crucible and drying it. Then crystallise it from ethanol and sublime it under reduced pressure. It can also be crystallised from water. [Marvel et al. J Am Chem Soc 47 3009 1925.]
Incompatibilities
May form explosive mixture with air.
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. Corrodes some metals. Unless inhibited,
violent polymerization can occur from heat, sunlight, and
contact with strong oxidizers
Waste Disposal
In accordance with 40CFR
165 recommendations for the disposal of pesticides and
pesticide containers. Must be disposed properly by following package label directions or by contacting your local or
federal environmental control agency, or by contacting
your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 107-27-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107-27:
(5*1)+(4*0)+(3*7)+(2*2)+(1*7)=37
37 % 10 = 7
So 107-27-7 is a valid CAS Registry Number.

The preparation of pentafluorophenyldihaloboranes from pentafluorophenylmercurials C6F5HgR and BX3: the dramatic dependence of the reaction direction on the ligand R
Bardin, Vadim V.,Adonin, Nicolay Yu.
, p. 1523 - 1531 (2019/07/22)
Abstract: In search of convenient preparations of C6F5BX2 (X = Cl, Br), reactions of C6F5HgR (R = C6F5, C6H5, C2H5, Br and Cl) with BX3 were studied. Under the action of BCl3 the order of the C–Hg bond cleavage is C6F5Hg–C6H5 > C6F5–HgC2H5 > C6F5–HgC6F5 >> C6F5–HgCl. With more reactive BBr3 the sequence is C6F5Hg–C6H5 > C6F5–HgC2H5 ~ C6F5Hg–C2H5 > C6F5–HgC6F5 ≥ C6F5–HgBr. During the study we found the simple way to alkyldibromoboranes which is presented by the preparation of C2H5BBr2 from C2H5HgBr and BBr3. It is the second example of synthesis of alkylmercury derivative in an addition to the earlier reported formation of cyclopropylmercurials from di(cyclopropyl)mercury and BX3.

Cation Radicals. 48. Evidence for Electron Transfer in the Alkylation of Thianthrene Cation Radical with Diethylmercury
Sugiyama, Kazuo,Shine, Henry J.
, p. 143 - 146 (2007/10/02)
Evidence is presented that reaction of thianthrene cation radical (Th(1+)) with Et2Hg in acetonitrile occurs by way of initial electron transfer.Products of reaction are thianthrene (Th), 5-ethylthianthrenium perchlorate (ThEt(1+)*ClO4(1-)), and EtHg(1+).When reaction is carried out under 18O2, not only the same products are formed but also thianthrene oxide (ThO), thianthrene dioxide (ThO2), acetaldehyde, and ethanol, all of which are enriched with 18O.Reaction therefore appears to lead initially to Et2Hg(1+) from which ethyl radicals are formed and are trapped with Th(1+) and O2.Reactions of EtO2 are believed to lead to the products containing 18O.Reaction of Ph2Hg with Th(1+) does not appear to follow this pathway.
