Imikoreshereze
Trimethyl borate ni reagent y'ingirakamaro mu gukora resins, waxes na rangi kandi ikora nk'umusemburo wa methylation. Nk'isoko ya boron, Trimethyl borate ikoreshwa mu gutegura ibintu bigabanya umuriro, anti-oxydants na corrosion inhibitors. Ikorana na Grignard reagents hanyuma igakurikizaho hydrolysis kugira ngo itegure aside boronic. Ikoreshwa kandi nk'intangiriro ya borate esters, ikoreshwa muri Suzuki coupling reaction. Ikoreshwa nk'umwuka upima neutron imbere y'icyuma gipima scintillation; nk'umusemburo wa diborane reactions.
Trimethyl borate ikorana na Grignard reagent cyangwa organolithium compounds kugira ngo itange dimethyl boronates, iyo nyuma yo kuvurwa aside y'amazi ihabwa aside boronic ijyanye nayo. Aside boronic cyangwa esters bivamo ni ingirakamaro mu mikorere itandukanye yo guhuza nk'iyo guhuza Suzuki na Chan-Lam. Ikoreshwa kandi mu gutegura sodium borohydride.
Gupakira no Kohereza
180KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Bika mu bubiko bukonje, bwumye kandi bufite umwuka mwiza. Irinde ahantu hashobora gutwika cyangwa gushyuha. Ubushyuhe bwo kubika ntibugomba kurenga 30°C. Bika igikoresho gifunze. Kigomba kubikwa ukwacyo kitari kumwe n'ibikomoka kuri ogisijeni, aside, nibindi, kandi wirinde kuvanga ububiko.
