Abubuwan Sinadarai:

Acrylic acid shine mafi sauƙi unsaturated carboxylic acid, tare da tsarin kwayoyin halitta wanda ya ƙunshi ƙungiyar vinyl da ƙungiyar carboxyl. Pure acrylic acid ruwa ne bayyananne, mara launi tare da siffa mai ƙamshi. Yawan 1.0511. Matsayin narkewa 14 ° C. Wurin tafasa 140.9°C. Tushen tafasa 140.9 ℃. Mai ƙarfi acidic. Lalata. Mai narkewa a cikin ruwa, ethanol da ether. Kemikal aiki. A sauƙaƙe polymerized cikin farin foda mai haske. Yana samar da propionic acid lokacin da aka rage. Yana samar da 2-chloropropionic acid idan an ƙara shi da hydrochloric acid. An yi amfani da shi a cikin shirye-shiryen resin acrylic, da dai sauransu. Har ila yau ana amfani da shi a cikin sauran kwayoyin halitta. Ana samun shi ta hanyar iskar shaka na acrolein ko hydrolysis na acrylonitrile, ko hadawa daga acetylene, carbon monoxide da ruwa, ko oxidized a ƙarƙashin matsin lamba daga ethylene da carbon monoxide.

Acrylic acid na iya sha da halayen halayen carboxylic acid, kuma ana iya samun esters masu dacewa ta hanyar amsawa tare da alcohols. Mafi na kowa acrylic esters sun hada da methyl acrylate, butyl acrylate, ethyl acrylate, da 2-ethylhexyl acrylate.

Acrylic acid da esters suna fuskantar halayen polymerization da kansu ko kuma lokacin da aka haɗa su da wasu monomers don samar da homopolymers ko copolymers.

Aikace-aikace:

Farawa abu don acrylates da polyacrylates da ake amfani da su a cikin robobi, tsarkakewar ruwa, takarda da suturar zane, da kayan aikin likita da haƙori.
