General Description
Clear slightly yellow liquid.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
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.
Fire Hazard
Flash point data for CYANOACRYLIC ACID METHYL ESTER are not available but CYANOACRYLIC ACID METHYL ESTER is probably non-flammable.
Hazard
Toxic by inhalation. Eye and upper respi-ratory tract irritant.
Potential Exposure
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.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with plenty of soap and water. Remove cured adhesive with
hot soapy water. Do not pull or scrape off adhesive as skin
can also come off. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if heart
action has stopped. Transfer promptly to a medical facility.
When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting.
Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid
for pulmonary edema, a doctor or authorized paramedic may
consider administering a drug or other inhalation therapy.
Shipping
UN3334 Aviation regulated liquid, n.o.s., Hazard
class: 9; Labels: 9-Miscellaneous hazardous material.
Technical Name Required.
Incompatibilities
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
Description
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.
Chemical Properties
Colorless liquid.
Chemical Properties
Methyl cyanoacrylate is a thick, clear liquid
adhesive. The odor threshold is 2.2 ppm.
Uses
In high-bond strength, fast-acting
glues (e.g., Krazy Glue); surgical use as tissue
adhesive
Uses
Surgical aid (tissue adhesive).
Health Hazard
Methyl 2-cyanoacrylate is an
irritant of the eyes and nose and can induce
occupational asthma.
Safety
Heating the polymer causes depolymerization of the cured MCA, producing gaseous products strongly irritant to lungs and eyes.
storage
Color Code- -Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Methyl 2-cyanoacrylateals or peroxides, since violent reactions occur. Store in orig-inal containers under refrigerated conditions at 2- -8℃.Where possible, automatically pump liquid from drums orother storage containers to process containers.
