Uses
Used as organic synthesis intermediates, binders, emulsifiers, coatings. Oleic acids and their esters are widely used in industry. Acrylates are often polymerized into polymers or copolymers during use. N-butyl acrylate (and methyl ester, ethyl ester, 2-ethylhexyl ester) is a soft monomer that can be combined with various hard monomers such as methyl methacrylate, styrene, acrylonitrile, vinyl acetate, etc. The monomer is copolymerized, crosslinked, grafted, etc., such as hydroxyethyl (meth) acrylate, hydroxypropyl acrylate, glycidyl ester, (meth) acrylamide, and a base derivative, to prepare 200-700 kinds of acrylics. Resin products (mainly emulsion, solvent and water soluble), widely used in coatings, adhesives, acrylic fiber modification, plastic modification, fiber and fabric processing, paper treatment, leather processing and acrylic rubber .
Health hazard
1 Inhalation, oral or absorption through the skin is harmful to the body. Its vapor or mist has a stimulating effect on the eyes, mucous membranes and respiratory tract. Poisoning has a burning sensation, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Skin contact: Remove contaminated clothing and wash skin thoroughly with soap and water.
Eye contact: Lift eyelids and rinse thoroughly with running water or saline. Seek medical attention.
Inhalation: Quickly leave the scene to the fresh air and keep the airway open. If breathing is difficult, give oxygen; if breathing stops, take artificial respiration immediately. Seek medical attention.
Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
