Whakamahinga
He matū whai hua te Trimethyl borate i roto i te hanga matū waro. Kei roto i te hanga kapia, ware pi me ngā peita, ā, he kaihoko methylation anō hoki. Hei pūtake boron, ka whakamahia te Trimethyl borate ki te whakarite i ngā aukati mura, ngā ārai-waikura me ngā aukati waikura. Ka tauhohe ki ngā matū Grignard, ā, ka whai muri ko te hydrolysis hei whakarite i te waikawa boronic. Ka whakamahia anō hoki hei matū mua mō ngā esters borate, e kitea ana te whakamahinga i roto i te tauhohenga hononga Suzuki. Ka whakamahia hei hau kite neutron i te aroaro o te kaute scintillation; hei kaiwhakatairanga i ngā tauhohenga diborane.
Ka tauhohe te trimethyl borate ki te matū Grignard, ki ngā matū organolithium rānei, ka puta he dimethyl boronates, ā, i muri i te maimoatanga waikawa wai ka puta he waikawa boronic e rite ana. He takawaenga whai hua ngā waikawa boronic, ngā esters rānei ka puta mai i roto i ngā tauhohenga whakawhiti-hononga pērā i te hononga Suzuki me te hononga Chan-Lam. Ka whakamahia hoki i roto i te whakarite i te konutai borohydride.
Te Tākai me te Tukunga
180KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Penapenahia ki roto i tētahi whare putunga hauhautanga, maroke, ā, he pai te hauhautanga. Me noho tawhiti atu i ngā pūtake ahi me te wera. Kaua te pāmahana rokiroki e neke ake i te 30 ℃. Me hiri te ipu. Me rongoa motuhake mai i ngā waikura, ngā waikawa, me ētahi atu, ā, kaua e whakaranua te rokiroki.
