Dab tsi yog organic teb phthalic anhydride (PA) hmoov tsis 85-44-9?
Phthalic anhydride (CASE NO. {{{{{{{{{}}}}}} Cov mis nyuj ua ke nrog cov molecular cov khoom xyaw nrog cov khoom siv molecular thiab molar mass 148.12 g / mol. Nyob rau hauv chav tsev kub, nws zoo li rab koob yees duab rab koob lossis flaky muaju nrog cov yeeb ncuab acid tsw ntxhiab.
Phthal anhydride yog sparingly soluble hauv dej txias (6 g / l ntawm 20 degree) tab sis yaj yooj yim hauv ethanol, ether, thiab benzene. Nws undergoes hydrolysis nyob rau hauv dej kub kom ua pthalic acid. Qhov sib xyaw ua ke muaj qhov ntom ntom ntawm 1.53 g / cmÃ, melting point ntawm 131.2 degree, boiling taw tes ntawm 295 degree, thiab cov khoom ua rau cov cwj pwm sublimation.
