Ukusetyenziswa
I-Trimethyl borate sisixhobo esiluncedo ekuveliseni i-organic synthesis. Ibandakanyeka ekuvelisweni kwee-resins, ii-waxes kunye neepeyinti kwaye isebenza njenge-methylation agent. Njengomthombo we-boron, i-Trimethyl borate isetyenziselwa ukulungiselela izinto ezithintela ilangatye, ii-anti-oxidants kunye ne-corrosion inhibitors. Isabela kunye nee-Grignard reagents ezilandelwa yi-hydrolysis ukulungiselela i-boronic acid. Ikwasetyenziswa njengomanduleli wee-borate esters, ezisetyenziswa kwi-Suzuki coupling reaction. Isetyenziswa njengegesi yokubona i-neutron xa kukho i-scintillation counter; njengomkhuthazi wee-diborane reactions.
I-Trimethyl borate isabela kunye ne-Grignard reagent okanye ii-organolithium compounds ukuze ivelise ii-dimethyl boronates, ezithi emva konyango lwe-aqueous acid zifumane ii-boronic acids ezifanayo. Ii-boronic acids okanye ii-esters eziphumayo ziluncedo kwi-intermediates ezahlukeneyo kwi-cross-coupling reactions ezifana ne-Suzuki coupling kunye ne-Chan-Lam coupling. Ikwasetyenziswa ekulungiseleleni i-sodium borohydride.
Ukupakishwa kunye nokuthunyelwa
180KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Gcina kwindawo yokugcina izinto epholileyo, eyomileyo, nengena umoya kakuhle. Hlala kude nemithombo yomlilo nobushushu. Ubushushu bokugcina akufuneki budlule kwi-30 ℃. Gcina isitya sivaliwe. Sifanele sigcinwe ngokwahlukileyo kwi-oxidants, ii-asidi, njl.njl., kwaye uphephe ukuxuba indawo yokugcina.
