Beschreibung
Methallyl alcohol is a colorless liquid with a pungent odor. Molecular weight= 72.12;Boiling point=114℃; Flash point=33℃. Hazard Identification (based on NFPA-704 M Rating System): Health 2, Flammability 3, Reactivity 0. Slightly soluble in water.
Chemische Eigenschaften
CLEAR COLOURLESS LIQUID
Verwenden
2-Methyl-2-propen-1-ol (MePro) attaches to hemicellulose acetylated galactoglucomannan (AcGGM) backbone providing it with pendant sites that allow subsequent cross-linking and hydrogel formation.
Vorbereitung Methode
Methallyl alcohol is prepared by hydrolysis of methallyl chloride in a 10 wt% aqueous sodium hydroxide solution. Pure methallyl alcohol can be obtained by methanolysis of methallyl acetate in the presence of catalytic amounts of bases. Methallyl alcohol is used in the preparation of polymerizable esters.
Allgemeine Beschreibung
A colorless liquid with a sharp pungent odor. Soluble in water and floats on water. Moderately toxic by ingestion and is an irritant to eyes and skin. Used in the chemical process industry.
Air & Water Reaktionen
Highly flammable and soluble in water.
Reaktivität anzeigen
Methallyl alcohol may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.
Health Hazard
Exposure can cause irritation of eyes, nose and throat.
mögliche Exposition
Used as an intermediate in organic synthesis
Erste Hilfe
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. 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.
Lager
Color Code—Red: Flammability Hazard: Store in a flammable liquid storage area or approved cabinet away from ignition sources and corrosive and reactive materials. Prior to working with this chemical you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from oxidizers and other incompatible materials. Metal containers involving the transfer of this chemical should be grounded and bonded. Drums must be equipped with self-closing valves. Sources of ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard.
Versand/Shipping
This compound requires a shipping label of “FLAMMABLE LIQUID.” It falls in Hazard Class 3 and Packing Group II.
Inkompatibilitäten
Forms explosive mixture with air. Incompatible with strong acids, caustics, aliphatic amines, isocyanates, DMSO, oxidizers.
