Kushandiswa
Trimethyl borate chinhu chinobatsira mukugadzirwa kweorganic. Inobatanidzwa mukugadzirwa kwemaresini, wakisi nependi uye inoshanda se methylation agent. Senzvimbo yeboron, Trimethyl borate inoshandiswa kugadzira zvinodzivisa moto, anti-oxidants uye corrosion inhibitors. Inoshanda neGrignard reagents inoteverwa ne hydrolysis kugadzira boronic acid. Inoshandiswawo senzira yekutanga ye borate esters, iyo inoshandiswa muSuzuki coupling reaction. Inoshandiswa se neutron detector gas kana paine scintillation counter; senzira yekukurudzira diborane reactions.
Trimethyl borate inoshanda neGrignard reagent kana organolithium compounds kuti ibudise dimethyl boronates, iyo mushure mekurapwa kwe aqueous acid inopa boronic acids inoenderana. Boronic acids kana esters dzinobva dzabuda dzinobatsira muzvikamu zvakasiyana-siyana zve cross-coupling zvakaita seSuzuki coupling neChan-Lam coupling. Inoshandiswawo mukugadzira sodium borohydride.
Kurongedza uye Kutumira
180KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Chengeta mudura rinotonhorera, rakaoma, uye rine mhepo inofema zvakanaka. Ramba kure nezvinhu zvinokonzera moto nekupisa. Tembiricha yekuchengetera haifanirwe kudarika 30 ℃. Chengeta mudziyo wakavharwa. Unofanira kuchengetwa wakaparadzana ne oxidants, acids, nezvimwewo, uye usasanganisa nzvimbo yekuchengetera.
