甲基丙烯酸甲酯提純步驟? 已有3人參與
|
|||
小弟剛開始接觸有機(jī)合成方面,零基礎(chǔ),現(xiàn)在需要把買來的化學(xué)純的甲基丙烯酸甲酯進(jìn)行提純,求教各位前輩,具體的提純方法步驟。。。小弟查了相關(guān)文獻(xiàn),都是一筆帶過,沒有具體的步驟 |

1. The monomer, methyl methacrylate, is generally stabilized by polymerization inhibitors. Remove stabilizers by extraction of 100 mL of methyl methacrylate with 20 mL of a solution of 5 g NaOH and 20 g NaCl in 100 mL distilled water. 2. Repeat this procedure twice to remove all stabilizer. 3. Wash the methyl methacrylate three times with 20 mL distilled water. 4. Store the water-saturated methyl methacrylate at 2–8°C. |
