1.Acrylic acid bụ carboxylic acid na-adịghị mfe nke na-adịghị mfe, nke nwere usoro ihe omimi nke nwere otu vinyl na otu carboxyl.Acid acrylic dị ọcha bụ mmiri na-enweghị agba, doro anya nke nwere isi na-akpasu iwe.Njupụta 1.0511.Ebe mgbaze 14 Celsius.Ebe esi mmiri ọkụ 140.9°C.Nnukwu acidic.Na-emebi emebi.Soluble na mmiri, ethanol na ether.Akwụkwọ kemịkalụ na-arụ ọrụ.Ngwa ngwa polymerized n'ime ntụ ntụ ọcha transperent.Na-emepụta propionic acid mgbe ọ na-ebelata.Na-emepụta 2-chloropropionic acid mgbe agbakwunyere ya na hydrochloric acid.Eji na nkwadebe nke acrylic resins, wdg A na-ejikwa na ndị ọzọ organic njikọ.Emepụtara site na oxidation nke acrolein ma ọ bụ hydrolysis nke acrylonitrile, mekwara ya site na acetylene, carbon monoxide na mmiri, ma ọ bụ mepụtara site na oxidation nke ethylene na carbon monoxide n'okpuru nrụgide.
2.Acrylic acid nwere ike nweta mmeghachi omume njirimara nke carboxylic acid na esters kwekọrọ nwere ike nweta site na mmeghachi omume na alcohols.Ndị esters acrylic kachasị na-agụnye methyl acrylate, butyl acrylate, ethyl acrylate, na 2-ethyl.
3.Acrylic acid na esters ya, site n'onwe ha ma ọ bụ gwakọta ya na monomers ndị ọzọ, na-enweta polymerization iji mepụta homopolymers ma ọ bụ copolymers.Ihe monomers a na-ahụkarị nke enwere ike imechi ya na acrylic acid gụnyere amides, Chemicalbook acrylonitrile, vinyl nwere, styrene na butadiene.A na-eji polymer ndị a na-emepụta ihe dị iche iche nke plastik, mkpuchi, adhesives, elastomers, polishes n'ala na agba.
