Dab tsi yog cov yam ntxwv ntawm acrylic acid (AA CAS 79-10-7)?

Acrylic acid (AA CAS 79-10-7)yog ib qho tseem ceeb organic synthesis raw khoom thiab hluavtaws cob monomer, thiab nws yog ib tug vinyl monomer nrog ib tug ceev heev polymerization tus nqi. Acrylic acid tseem hu ua: acrylic (ester) copolymer, acrylic acid CAS No .: 25035-69-2.

Acrylic acid yog qhov yooj yim tshaj plaws unsaturated carboxylic acid, muaj xws li ib pawg vinyl thiab ib pawg carboxyl. Ntshiab acrylic acid yog cov xim tsis muaj xim, ntshiab kua nrog ib qho txawv ntse tsw. Nws yog miscible nrog dej, cawv, ether thiab chloroform, thiab yog tsim los ntawm propylene, uas tau los ntawm cov roj refineries.

txog peb

Henan Gneebiotau tsim nyob rau hauv 2016, ua raws li lub tswv yim ntawm "cov khoom siv tshuaj lom neeg thoob ntiaj teb" thiab tsom mus rau qib siab -kev lag luam tshuaj lom neeg zoo. Lub tuam txhab feem ntau cuam tshuam cov khoom siv tshuaj lom neeg, xws li dichloromethane; methyl sulfoxide DMSO ( qib kev lag luam thiab kws tshuaj); ethylene glycol (MEG); p-Xylene, thiab lwm yam.

Tag nrho peb cov khoom siv tshuaj lom neeg tau txais cov ntawv pov thawj thoob ntiaj teb suav nrog REACH, ISO, FMQS, HALAL, thiab Halal ntawv pov thawj, kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev lees paub thoob ntiaj teb, Peb muaj cov tsev khaws khoom hauv coreports xws li Qingdao, Tianiin, thiab Shanghai, nrog rau 15-hnub kev xa khoom xa tuaj.
