CLEAR COLOURLESS LIQUID

The Uses of Methallyl alcohol

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.

Production Methods

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.

General Description

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 Reactions

Highly flammable and soluble in water.

Reactivity Profile

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.

Potential Exposure

Used as an intermediate in organic synthesis

First aid

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.

storage
