Muaj ob txoj hauv kev tseem ceeb rau kev npaj adipic acid dihydrazide, uas yog ib qho - kauj ruam thiab ob - kauj ruam.
Ib kauj ruam: adipic acid thiab hydrazine hydrate tau ncaj qha los tsim ADH.
Adipic acid thiab hydrazine hydrate yog refluxed nyob rau hauv cov cua sov rau ib lub sij hawm ntawm lub sij hawm, ces txias thiab crystallized, thiab khoom ADH yog tau tom qab pom, ntxuav, ziab thiab recrystallization. Txoj kev no yog qhov yooj yim thiab yooj yim rau kev khiav lag luam, tab sis cov txiaj ntsig qis, tsis ntau tshaj 65%.
Ob kauj ruam txoj kev: hais txog esterification cov tshuaj tiv thaiv thiab hydrazidation cov tshuaj tiv thaiv:
Thawj kauj ruam yog esterification los ua ke dimethyl / ethyl adipate.
Hauv theem ob hydrazidation cov tshuaj tiv thaiv, ester thiab hydrazine hydrate hnov mob los tsim ADH. Nyob rau hauv thawj kauj ruam esterification cov tshuaj tiv thaiv, concentrated sulfuric acid feem ntau yog siv los ua catalyst, uas muaj cov teeb meem ntawm muaj zog corrosiveness, loj npaum li cas ntawm cov organic wastewater nrog siab ntsev cov ntsiab lus, zoo ib puag ncig kev puas tsuaj, thiab ntau sab cov tshuaj tiv thaiv impurities.
Ib puag ncig tus phooj ywg catalysts, xws li cov kua qaub, heteropoly acids thiab hlau tebchaw, tau txais kev saib xyuas ntau thiab ntau dua, tab sis lawv feem ntau muaj qhov tsis zoo xws li cov nqi siab thiab cov txheej txheem sib xyaw ua ke, uas tsim nyog rau kev kuaj ntsuas thiab kev loj hlob. Tseem muaj ntau yam teeb meem uas yuav tsum tau daws nyob rau hauv kev tsim thiab siv. Tsis tas li ntawd, ob txoj kev saum toj no yog ua raws li tus nqi kim hydrazine hydrate raws li cov khoom siv raw, thiab cov nqi tsim khoom yog siab.
Ib txoj hauv kev zoo rau kev npaj adipic acid dihydrazide muaj cov kauj ruam hauv qab no:
