The formula



Allyl alcohol (IUPAC name: prop-2-en-1-ol) is an organic compound with the structural formula CH2=CHCH2OH. Like many alcohols, it is a water-soluble, colourless liquid, but it is more toxic than typical small alcohols. Allyl alcohol is used as a raw material for the production of glycerol, but is also used as a precursor to many specialized compounds such as flame-resistant materials, drying oils, and plasticizers.[3] Today allyl alcohol can be obtained by many methods. Allyl alcohol is the smallest representative of the allylic alcohols.

1.Allyl alcohol is mainly converted to glycidol, which is a chemical intermediate in the synthesis of glycerol, glycidyl ethers, esters and amines. Also, a variety of polymerizable esters are prepared from allyl alcohol, e.g. diallyl phthalate.

2. SAA is used as a functional additive in a wide variety of coatings such as urethanes, alkyds and acrylics.

3. SAA has been shown to improve adhesion, increase weatherability, and enhance gloss, hardness and water resistance.

4. SAA is also used in water-based and radiation-curable coatings.
