废烟叶制取草酸的研究

Study on the Production of Oxalic Acid from Tobaccos

使用以钒化合物为主的复合催化剂，在温和的反应条件下，将废烟叶经硝酸氧化制取了草酸。收率为４０％以上，纯度可达９９．０％以上。为废烟叶的综合利用开辟了一条新途径。

the production for Oxalic acid by oxidation of tobaccos with complex catalyst-vandic compound and catalyst promoter in a moderate condition was reported. Its yiedwas above 40% with purity of more than 99.0%. A new course for tobaccos application wasmade.
