Properties and stability
1. Avoid contact with oxidants.
2. Flammable, harmful when taken orally or in contact with skin, and irritating to eyes, respiratory system and skin.
Storage method
1. Store in a cool, ventilated warehouse. Keep away from fire, heat sources and anti-static. The packaging is sealed. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.
Synthesis method
It can be obtained from the reaction of acrylamide and allyl alcohol under the action of concentrated acid and H2O2, or it can be obtained from allyl acetate and methyl methacrylate. Derived from transesterification. It can also be produced by reacting methacrylic acid with allyl alcohol, using p-toluenesulfonic acid as a catalyst, and refluxing in the presence of the polymerization inhibitor hydroquinone. The generated water is continuously removed during the reaction. After the reaction is completed, the excess is recovered by fractionation. Allyl alcohol, the product was purified by distillation under reduced pressure.
Purpose
1. Widely used as comonomer, grafting monomer and cross-linking agent for tooth repair in the preparation of organic glass.
