説明
Methyl cyanoacrylate (MCA) is an organic compound that contains several functional groups, a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.It can be encountered under many trade names. Methyl cyanoacrylate is less commonly encountered than ethyl cyanoacrylate.
It is soluble in acetone, methyl ethyl ketone, nitro methane, and dichloromethane. MCA polymerizes rapidly in presence of moisture.
化学的特性
Colorless liquid.
使用
Surgical aid (tissue adhesive).
一般的な説明
Clear slightly yellow liquid.
空気と水の反応
Insoluble in water.
反応プロフィール
CYANOACRYLIC ACID METHYL ESTER is an unsaturated aliphatic nitrile and ester. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
危険性
Toxic by inhalation. Eye and upper respi-ratory tract irritant.
健康ハザード
Methyl 2-cyanoacrylate is an
irritant of the eyes and nose and can induce
occupational asthma.
火災危険
Flash point data for CYANOACRYLIC ACID METHYL ESTER are not available but CYANOACRYLIC ACID METHYL ESTER is probably non-flammable.
安全性プロファイル
Moderately toxic by
ingestion and inhalation routes.
Experimental reproductive effects. A human
eye irritant. Can bond the eyelids or skin
surfaces instantly. Mutation data reported.
When heated to decomposition it emits
toxic fumes of NOx and CN-.
安全性
Heating the polymer causes depolymerization of the cured MCA, producing gaseous products strongly irritant to lungs and eyes.
職業ばく露
Methyl 2-cyanoacrylate is used in production of coatings and textiles; in the manufacture of
quick-setting, high-strength, adhesive cements. Often found
around the home; bonds eyes and skin in seconds. Keep out
of the reach of children.

class: 9; Labels: 9-Miscellaneous hazardous material.
Technical Name Required.
不和合性
Compounds of the carboxyl group react
with all bases, both inorganic and organic (i.e., amines)
releasing substantial heat, water and a salt that may be
harmful. Incompatible with arsenic compounds (releases
hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides
(releasing heat, toxic, and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur). Reacts violently with water, bases, and
peroxides. Contact with alcohols, water, amines, and alkalis
can cause rapid polymerization
