Chemical Properties:

Acrylic acid yog qhov yooj yim tshaj plaws unsaturated carboxylic acid, nrog cov qauv molecular uas muaj ib pawg vinyl thiab pawg carboxyl. Acrylic ntshiab ntshiab yog cov kua ntshiab, tsis muaj xim nrog cov yam ntxwv pungent tsw. Qhov ceev 1.0511. Melting point 14 ° C. Kub taw tes 140.9 ° C. Kub taw tes 140.9 ℃. Muaj zog acidic. Corrosive. Soluble hauv dej, ethanol thiab ether. Tshuaj active. Yooj yim polymerized rau hauv pob tshab dawb hmoov. Ua propionic acid thaum txo qis. Ua 2-chloropropionic acid thaum ntxiv nrog hydrochloric acid. Siv nyob rau hauv kev npaj ntawm acrylic resin, thiab lwm yam kuj siv nyob rau hauv lwm yam organic synthesis. Nws yog tau los ntawm oxidation ntawm acrolein los yog hydrolysis ntawm acrylonitrile, los yog synthesized los ntawm acetylene, carbon monoxide thiab dej, los yog oxidized nyob rau hauv siab los ntawm ethylene thiab carbon monoxide.

Acrylic acid tuaj yeem dhau los ua cov tshuaj tiv thaiv ntawm carboxylic acids, thiab cov esters sib xws tuaj yeem tau los ntawm cov tshuaj tiv thaiv nrog cawv. Feem ntau cov acrylic esters muaj xws li methyl acrylate, butyl acrylate, ethyl acrylate, thiab 2-ethylhexyl acrylate.

Acrylic acid thiab nws cov esters tau txais cov tshuaj tiv thaiv polymerization ntawm lawv tus kheej lossis thaum sib xyaw nrog lwm cov monomers los ua homopolymers lossis copolymer.

Daim ntawv thov:

Pib cov khoom siv rau acrylates thiab polyacrylates siv nyob rau hauv cov yas, dej purification, ntawv thiab ntaub txheej, thiab cov ntaub ntawv kho mob thiab kho hniav.
