Ukusetshenziswa
I-Trimethyl borate iyi-reagent ewusizo ekuhlanganisweni kwezinto eziphilayo. Ihilelekile ekukhiqizweni kwama-resin, ama-waxes kanye nopende futhi isebenza njenge-methylation agent. Njengomthombo we-boron, i-Trimethyl borate isetshenziselwa ukulungiselela ama-flame retardants, ama-anti-oxidants kanye nama-corrosion inhibitors. Isabela nama-Grignard reagents kulandele i-hydrolysis ukulungiselela i-boronic acid. Iphinde isetshenziswe njengesandulela sama-borate esters, athola ukusetshenziswa ku-Suzuki coupling reaction. Isetshenziswa njengegesi yokuthola i-neutron lapho kukhona i-scintillation counter; njengomgqugquzeli we-diborane reactions.
I-Trimethyl borate iphendula nge-Grignard reagent noma ama-organolithium compounds ukuze ikhiqize ama-dimethyl boronates, okuthi uma kwelashwa nge-aqueous acid kamuva athole ama-boronic acid ahambisanayo. Ama-boronic acid noma ama-ester aphumelayo ayizihlanganisi eziwusizo ekusebenzelaneni okuhlukahlukene kokuhlangana okufana nokuhlanganiswa kwe-Suzuki kanye nokuhlanganiswa kwe-Chan-Lam. Iphinde isetshenziswe ekulungiseleleni i-sodium borohydride.
Ukupakisha Nokuthumela
180KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Gcina endaweni yokugcina izinto epholile, eyomile, futhi enomoya omuhle. Hlala kude nemithombo yomlilo nokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30 ℃. Gcina isitsha sivaliwe. Kufanele sigcinwe ngokwehlukana nama-oxidants, ama-acid, njll., futhi ugweme ukuxuba indawo yokugcina.
