職業(yè)ばく露
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.
輸送方法
UN2277 Ethyl methacrylate, stabilized, Hazard
Class: 3; Labels: 3-Flammable liquid
純化方法
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.]
不和合性
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
廃棄物の処理
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
