Synthesis ntawm1-hexanol kua:
(1) Hauv kev lag luam, nws yog feem ntau npaj los ntawm catalytic hydrogenation thiab txo qis hexanoic acid. Nyob rau hauv loj - Ntxaij muaj ntau lawm, ethylene yog siv los ua cov khoom siv raw. Nyob rau hauv lub xub ntiag ntawm lub trriethyl aluminals, trihexyl aluminium yog thawj synthesized. Trhihyl aluminium yog oxidized kom tau triexoxyaluminum, thiab tom kawg yog hydrolyzed mus n - hexanol. Qhov no yog cov qauv Ziegler nto moo, uas yog siv los ua raws li cov cawv me me nrog cov roj carbon. Peb {{- Cov kauj ruam kev tiv thaiv kab zauv yog raws li hauv qab no:
Synthesis ntawm Trietyl aluminium: 2al+3 h2 + 6C2H42al (c2H5)3
Saw kev loj hlob tawm tsam: al (c2H5)3 + 6C2H4 → [C2H5(C2H4)2]3Al
Oxidation: 2 [c2H5(C2H4)2] 3al + 32 → 2[C2H5(C2H4)2O]3Al
Hydrolysis: 2 [c2H5(C2H4)2O]3Al + 3 h2O→6C2H5(C2H4)2Oh + al2O3
Nws tseem tuaj yeem tsim los ntawm oxidation ntawm n- hexane, tab sis cov khoom tau sib xyaw ua ke ntawm txawv hexanol}} hexanol tuaj yeem tau txais tom qab distillation thiab sib cais.
Hexanol feem ntau muaj lwm yam cawv, uas nyuaj rau cais. Txoj kev zoo dua yog Esterification nrog P- hydoncybly lossis calcium sulfate lossis calcium sulfate, distillation, thiab kev cuam tshuam ntawm n- hexanol feem.
(2) Ethyl HeXanoate tau siv ua cov khoom siv raw thiab txo nrog cov pa hlau hauv kev siv hlau. Cov khoom lag luam yog n - hexanol thiab ethanol. Ntshiab n - hexanol tau txais los ntawm rectification thiab sib cais.
(3) Hauv chav kuaj, Butyl Magnesium bromide tuaj yeem npaj los ntawm cov chips, thiab tom qab ntawd reacting nrog ethylene oxide kom tau txais hexanol. Nyob rau hauv lub xub ntiag ntawm catalyst iodine, lub anhydrod ether etheth tov ntawm bromobutane yog reacted nrog cov chips magnesium hauv qab nplawm. Hauv kev tshuaj tiv thaiv, reflux thiab anhydrous yuav tsum tau ua tiav. Qhov poob nrawm nrawm nrawm ntawm Bromobutane thiab anhydrous ether yuav tsum tau tswj kom cov tshuaj ntsuam ua kua. Tom qab kev poob qis tiav, Ethylene oxide tau qhia. Nyob rau hauv lub xeev txias, kev pub mis ceev yog tswj tau los tswj cov tshuaj tiv thaiv kub ntawm 10 degree. Tom qab kev pub mis ua tiav, cov cua txias txias yog nres thiab ntsuas kub ntawm cov tshuaj tiv thaiv kab mob yog nce me ntsis npau npau. Tom qab npau npau, cua sov cov reactants nyob hauv dej da dej. Thaum ib nrab ntawm tag nrho cov nyiaj yog evaporated, ntxiv tus nqi uas tsim nyog ntawm kev ua kom deb li 65℃c, thiab tom qab ntawd kom tiav refruxe rau lub viscosity ntawm kev sib tov. Tom qab txias, ntxiv cov dej khov uas haum rau hydrolysis, thiab ntxiv 30% sulfuric acid thaum txias kom txog thaum cov precipitated magnesium yog tag nrho. Tom qab ntawd, chav distillation yog nqa tawm ntxiv 20% sodium hydroxide rau cov txheej txheej dej, thiab tom qab ntawd cov txheej txheem distillated, thiab tom qab ntawd cov txheej txheem hauv qab, thiab tom qab ntawd cov txheej txheem ntawm cov roj av, thiab tom qab ntawd cov txheej txheem ntawm cov roj av
