Phthalic Anhydride los ntawm Phthalic Acid

Phthalic anhydride los ntawm phthalic acid feem ntau yog muab los ntawm phthalic acid, ib tug dawb crystalline hmoov nrog ib tug qab ntxiag tsw. Cov txheej txheem ntawm kev tsim phthalic anhydride los ntawm phthalic acid muaj ob peb kauj ruam uas yuav tsum tau kev precision, kev txawj ntse, thiab cov cuab yeej tshwj xeeb.

Kev tsim cov phthalic anhydride los ntawm phthalic acid yog thawj lub cev qhuav dej phthalic acid los ua anhydride. Cov txheej txheem no suav nrog cua sov phthalic acid rau qhov kub thiab txias, ua rau nws poob dej molecules thiab tsim anhydride. Cov khoom tau txais yog phthalic anhydride, uas yog ib tug dawb, crystalline, thiab heev reactive compound.
