Muaj peb txoj hauv kev tseem ceeb rau kev sib txuas ntawm 2-z-hexanoic acid:
① oxidation ntawm 2-ethylhexanol;
② 2-ethylhexene aldehyde oxidation txoj kev;
③ 2-ethylhexanol los ntawm hydrogen esterification
2-ethylhexanol oxidation txoj kev:
Nws yog tsuas yog siv los ua 2-ethylhexanol nrog poov tshuaj permanganate nyob rau hauv alkaline los yog acidic nruab nrab los tsim poov tshuaj 2-ethylhexanoate, uas yog acidified nrog concentrated sulfuric acid tom qab txias rau chav tsev kub;
Dehydrogenation thiab esterification ntawm 2-ethylhexanol:
2-ethylhexanol thiab sodium hydroxide yog siv rau oxidative dehydrogenation los npaj sodium 2-ethylhexanoate, uas yog neutralized nrog sulfuric acid kom tau isooctanoic acid.
Ob txoj kev no yog ob qho tib si me me - nplai cov txheej txheem ib txwm ua, thiab qhov teeb meem ntawm "peb qhov pov tseg" yog qhov hnyav Firstly, 2-ethylhexenal (tseem hu ua isooctenal) yog xaiv hydrogenated los tsim 2-ethylhexenal (tseem hu ua isooctenal). Tom qab ntawd, 2-ethylhexenal yog oxidized nyob rau hauv cov kua theem nrog cua los yog oxygen nyob rau hauv qhov kev txiav txim ntawm coolate catalyst los tsim isooctanoic acid. Txoj hauv kev no yog qhov tsim nyog thiab yog qhov chaw kub hauv kev tshawb fawb ua ntej.
Kev tshawb fawb txheej txheem ntawm kev sib txuas ntawm isooctanoic acid los ntawm aldehyde oxidation:
Lub synthesis ntawm2-Ethylhexanoic acidLos ntawm aldehyde oxidation feem ntau muab faib ua ob theem: hydrogenation ntawm ISOOCTENE aldehyde thiab oxidation ntawm isooctyl aldehyde. Lub synthesis ntawm isooctanoic acid los ntawm aldehyde oxidation txoj kev muaj cov txheej txheem tsim nyog, tsawg noj, ruaj khov khoom zoo thiab siab yield. Cov khoom nruab nrab thiab cov khoom tsim tawm hauv cov txheej txheem tshuaj tiv thaiv yog cov tshuaj lom neeg tsawg tsawg, uas ua rau muaj kuab paug tsawg rau ib puag ncig. Lub synthesis ntawm isooctanoic acid los ntawm aldehyde oxidation txoj kev yog ib qho kev tshawb fawb kub hauv tsev thiab txawv teb chaws ua ntej H.
