Txoj kev npaj ntawm stannous octanoate T-9 feem ntau suav nrog cov hauv qab no:
Aldehyde disproportionation txoj kev: Txoj kev no koom nrog cov tshuaj tiv thaiv ntawm stannous ntsev nrog isooctyl aldehyde nyob rau hauv tej yam kev mob los tsim stannous octanoate los ntawm tus kheej-disproportionation cov tshuaj tiv thaiv ntawm aldehyde. Txawm li cas los xij, vim qhov nyuaj thiab tsis tshua muaj kev xaiv ntawm aldehyde disproportionation cov tshuaj tiv thaiv, txoj kev no tsis muaj nyob rau hauv qhov tseeb ntau lawm.
Txoj kev Anhydride: stannous ntsev (xws li stannous chloride los yog stannous oxide) yog reacted nrog isooctyl anhydride nyob rau hauv ib tug tsim nyog hnyav thiab tej yam kev mob los tsim stannous octanoate thiab coj hydrogen halide los yog dej. Tom qab cov tshuaj tiv thaiv tiav lawm, cov tshuaj tsis ua haujlwm raug tshem tawm los ntawm kev pom thiab distillation kom tau txais cov ntshiab stannous octanoate.
Ob chav decomposition txoj kev: stannous ntsev yog siv los teb nrog sodium (los yog poov tshuaj) isooctyl ntsev nyob rau hauv cov organic hnyav los tsim stannous octanoate thiab inorganic ntsev. Lub ntsiab tseem ceeb yog tswj cov pH tus nqi thiab cov tshuaj tiv thaiv kab mob ntawm cov tshuaj tiv thaiv kab mob los txhawb kev tsim ntawm stannous octanoate thiab inhibit sab kev xav.
Electrochemical txoj kev: Nws yog nqa tawm nyob rau hauv ib tug electrolytic cell, siv tam sim no los ntawm lub anode thiab cathode kom txo tau cov ntsev stannous rau stannous octoate ntawm lub cathode. Txoj kev no muaj qhov zoo ntawm cov txheej txheem tsim khoom ruaj khov, kev ua haujlwm yooj yim, tsis tshua muaj nqi ntau lawm thiab cov khoom lag luam zoo, tab sis nws daim ntawv thov kev lag luam tsis tau tshaj tawm.
Cov kauj ruam kev sim tshwj xeeb:
Nyob rau hauv ib lub khob peb-caj dab nruab nrog ib tug neeg kho tshuab stirrer, tus pas ntsuas kub thiab ib tug reflux condenser, ntxiv isooctanoic acid thiab stannous oxide.
Nyob rau hauv kev tiv thaiv nitrogen, qhov sib tov yog rhuab mus txog 140 degree thiab cov tshuaj tiv thaiv ntev li ntawm 90 feeb.
Tom qab cov tshuaj tiv thaiv tiav lawm, lim tawm cov tsis muaj kev cuam tshuam stannous oxide.
Cov dej thiab cov isooctanoic acid tsis tau raug tshem tawm los ntawm lub tshuab nqus tsev distillation kom tau txais cov ntshiab stannous octoate.
