六次甲基四胺(HMT)的作用 已有2人參與
|
|
看到一篇水熱法制備Co(OH)2的文獻(xiàn)中加入了HMT 想請(qǐng)問(wèn)大家一下六次甲基四胺(HMT)在水熱反應(yīng)中的作用?是一種還原劑嗎?還是一種取向性生長(zhǎng)的。。 下面是文獻(xiàn)中的相關(guān)段落 Briefly, cobalt (II) chloride hexahydrate (CoCl2·6H2O, Sinopharm Chemical Reagent Co. Ltd), sodium chloride (NaCl, Shanghai Lingfeng Chemical Regent Co. Ltd) and hexamethylene tetramine (HMT, Sinopharm Chemical Reagent Co. Ltd) were dissolved in 100 cm3 of a 9:1 mixture of ultrapure water and anhydrous ethanol, giving the final concentrations of 10, 40 and 60 mM, respectively. Then the reaction solution was heated at 90 oC in the oil bath under magnetic stirring. After being heated for about 1 h, the pink solution turned from pink color to green color. Solid products were collected by centrifugation at 6000 rpm for 5 min, washed with ultrapure water and anhydrous ethanol for several times. The final products were air-dried at room temperature. |
