Hoʻohana
He mea pono ka Trimethyl borate i ka synthesis organik. Pili ia i ka hana ʻana o nā resins, waxes a me nā pena a hana ma ke ʻano he mea methylation. Ma ke ʻano he kumu boron, hoʻohana ʻia ʻo Trimethyl borate e hoʻomākaukau i nā mea pale ahi, nā anti-oxidants a me nā mea pale corrosion. Hoʻopili ia me nā reagents Grignard a ukali ʻia e ka hydrolysis e hoʻomākaukau i ka waikawa boronic. Hoʻohana ʻia hoʻi ia ma ke ʻano he precursor o nā esters borate, kahi e loaʻa ai ka hoʻohana ʻana i ka hopena hoʻopili Suzuki. Hoʻohana ʻia ia ma ke ʻano he kinoea ʻike neutron i ke alo o kahi counter scintillation; ma ke ʻano he mea hoʻolaha o nā hopena diborane.
Hoʻopili ka Trimethyl borate me kahi reagent Grignard a i ʻole nā hui organolithium e hua mai i ka dimethyl boronates, kahi ma hope o ka mālama ʻana i ka waikawa wai ma hope e hāʻawi i nā waikawa boronic like. ʻO nā waikawa boronic a i ʻole esters i loaʻa he mau mea waena pono i nā ʻano hana cross-coupling like ʻole e like me ka Suzuki coupling a me Chan-Lam coupling. Hoʻohana ʻia hoʻi ia i ka hoʻomākaukau ʻana o ka sodium borohydride.
ʻŌpala a me ka Hoʻouna ʻana
180KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
E mālama i loko o kahi hale waihona meaʻai anuanu, maloʻo, a me ka ea maikaʻi. E noho mamao aku mai nā kumu ahi a me ka wela. ʻAʻole pono e ʻoi aku ka mahana o ka mālama ʻana ma mua o 30 ℃. E hoʻopaʻa pono i ka ipu. Pono e mālama ʻokoʻa ʻia mai nā mea hoʻomake, nā waikawa, a me nā mea ʻē aʻe, a pale i ka hoʻohuihui ʻana i ka mālama ʻana.
