Kagwiritsidwe Ntchito
Trimethyl borate ndi reagent yothandiza popanga zinthu zachilengedwe. Imagwira ntchito popanga ma resin, sera ndi utoto ndipo imagwira ntchito ngati methylation. Monga gwero la boron, Trimethyl borate imagwiritsidwa ntchito pokonzekera zoletsa moto, anti-oxidants ndi zoletsa dzimbiri. Imagwira ntchito ndi Grignard reagents kutsatiridwa ndi hydrolysis kukonzekera boronic acid. Imagwiritsidwanso ntchito ngati choyambira cha borate esters, chomwe chimagwiritsidwa ntchito mu Suzuki coupling reaction. Imagwiritsidwa ntchito ngati mpweya wozindikira neutron pamaso pa scintillation counter; ngati cholimbikitsa diborane reactions.
Trimethyl borate imakumana ndi Grignard reagent kapena organolithium compounds kuti ipange dimethyl boronates, zomwe pambuyo pake zikagwiritsidwa ntchito ndi aqueous acid zimakhala ndi boronic acids yofanana. Boronic acids kapena esters zomwe zimatsatira zimakhala zothandiza pakati pa zochitika zosiyanasiyana monga Suzuki coupling ndi Chan-Lam coupling. Imagwiritsidwanso ntchito pokonzekera sodium borohydride.
Kulongedza ndi Kutumiza
180KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Sungani m'nyumba yosungiramo zinthu yozizira, youma, komanso yodutsa mpweya wabwino. Khalani kutali ndi zinthu zomwe zimayambitsa moto ndi kutentha. Kutentha kwa malo osungiramo zinthu sikuyenera kupitirira 30 ℃. Sungani chidebecho chotsekedwa. Chiyenera kusungidwa padera ndi zinthu zowononga ma oxidants, ma acid, ndi zina zotero, ndipo pewani kusakaniza malo osungiramo zinthu.
