Succinic Anhydride (SA), CAS No. 108-30-5, molecular mis C₄H₄O₃, yog dawb flaky khoom nrog melting point ntawm kwv yees li 117-121℃.Nws yog ib qho tseem ceeb cyclic acid anhydride uas muaj reactive anhydride pawg, thiab soluble nyob rau hauv organic solvents xws li acetone thiab ethyl acetate.
Succinic anhydride yog tsim los ntawm catalytic hydrogenation ntawm maleic anhydride (MA). Nyob rau hauv cov txheej txheem no, cov pa roj carbon - carbon ob daim ntawv cog lus nyob rau hauv cov txiv neej anhydride molecule undergoes xaiv hydrogenation nyob rau hauv lub xub ntiag ntawm ib tug catalyst, converting nws mus rau hauv lub structurally ruaj khov succinic anhydride. Txoj kev no siv cov ntaub ntawv raw khoom yooj yim thiab koom nrog txoj kev tawm tsam ncaj qha, ua rau nws yog txoj hauv kev tseem ceeb rau kev tsim khoom ntawm succinic anhydride.
Thaum lub sij hawm tsim khoom, lub purity ntawm cov txiv neej anhydride feedstock, catalytic hydrogenation tej yam kev mob, thiab tom qab purification txheej txheem ncaj qha cuam tshuam lub purity thiab stability ntawm cov khoom kawg. Kev ua tiav siab -purity succinic anhydride (Ntau dua lossis sib npaug li 99.5%) yuav tsum tau tswj nruj me ntsis ntawm cov impurities tseem ceeb, xws li cov kab lus thiab cov dej noo.
