Mawu Oyamba
mankhwala katundu
Madzi osawoneka bwino oyaka ndi asphyxiating aldehyde fungo. Zosungunuka pang'ono m'madzi. Zosakaniza ndi ethanol, ether, ethyl acetate, acetone, toluene, zosiyanasiyana zosungunulira organic ndi mafuta.
Gwiritsani ntchito
Amagwiritsidwa ntchito mu organic synthesis komanso zopangira popanga zonunkhira
Gwiritsani ntchito
GB 2760-96 imatchula zonunkhira zomwe zimaloledwa kugwiritsidwa ntchito. Amagwiritsidwa ntchito makamaka pokonzekera nthochi, caramel ndi zokometsera zina za zipatso.
Gwiritsani ntchito
butyraldehyde ndi yofunika kwambiri pakati. n-butanol ikhoza kupangidwa ndi hydrogenation ya n-butanal; 2-ethylhexanol ikhoza kupangidwa ndi condensation dehydration ndiyeno hydrogenation, ndipo n-butanol ndi 2-ethylhexanol ndi zipangizo zazikulu za plasticizers. asidi n-butyric akhoza kupangidwa ndi makutidwe ndi okosijeni wa asidi n-butyric; trimethylolpropane ikhoza kupangidwa ndi condensation ndi formaldehyde, yomwe ndi plasticizer ya synthesis ya alkyd resin ndi zopangira zopangira mafuta owumitsa mpweya; condensation ndi phenol kupanga mafuta sungunuka utomoni; condensation ndi urea akhoza kutulutsa utomoni sungunuka mowa; mankhwala condensed ndi polyvinyl mowa, butylamine, thiourea, diphenylguanidine kapena methyl carbamate ndi zopangira ndi, condensation ndi mowa zosiyanasiyana ntchito monga zosungunulira kwa mapadi, utomoni, mphira ndi mankhwala mankhwala; makampani opanga mankhwala amagwiritsidwa ntchito kupanga "Mianerton", "pyrimethamine", ndi amylamide.
Gwiritsani ntchito
Guluu mphira, accelerator mphira, kupanga utomoni ester, kupanga asidi butyric, etc. Hexane njira yake ndi reagent kudziwa ozoni. Amagwiritsidwa ntchito ngati zosungunulira za lipids, amagwiritsidwanso ntchito pokonza zokometsera ndi zonunkhira komanso ngati chosungira.
Njira yopangira
pakali pano, njira zopangira za butyraldehyde zimagwiritsa ntchito njira zotsatirazi: 1. propylene carbonyl synthesis propylene ndi kaphatikizidwe ka gasi amachita carbonyl synthesis reaction pamaso pa Co kapena Rh chothandizira kuti apange n-butyraldehyde ndi isobutyraldehyde. Chifukwa cha zosiyana siyana zomwe zimagwiritsidwa ntchito ndi ndondomeko zomwe zimagwiritsidwa ntchito, zimatha kugawidwa kukhala carbonyl synthesis yapamwamba kwambiri ndi cobalt carbonyl monga chothandizira komanso chochepa cha carbonyl synthesis ndi rhodium carbonyl phosphine complex monga chothandizira. Njira yoponderezedwa kwambiri imakhala ndi kuthamanga kwambiri komanso zinthu zambiri zomwe zimapangidwira, motero zimawonjezera mtengo wopangira. The low-pressure carbonyl synthesis njira imakhala ndi mphamvu yotsika kwambiri, chiŵerengero chabwino cha isomer cha 8-10: 1, zochepa zopangira, kutembenuka kwakukulu, zopangira zochepa, kugwiritsa ntchito mphamvu zochepa, zipangizo zosavuta, njira zazifupi, zowonetsera bwino kwambiri zachuma ndi chitukuko chofulumira. 2. Acetaldehyde condensation njira. 3. Njira ya Butanol oxidative dehydrogenation imagwiritsa ntchito siliva ngati chothandizira, ndipo butanol imakokedwa ndi mpweya mu sitepe imodzi, ndiyeno ma reactants amafupikitsidwa, kupatukana, ndi kukonzedwa kuti apeze mankhwala omalizidwa.
Njira yopangira
Iwo analandira ndi youma distillation wa kashiamu butyrate ndi kashiamu formate.
Mpweyawu umapezeka mwa dehydrogenation wa chothandizira.
