摘要
使用过氧化二叔丁基模拟皮革加脂剂及油脂氧化的产物——二烃基过氧化物,在加热温度105℃条件下,使过氧化二叔丁基分别对CrCl3、CrCl3-抗氧剂1010溶液进行氧化处理,定期测定溶液中Cr(Ⅵ)的含量,研究二烃基过氧化物及自由基清除剂(抗氧剂1010)对皮革中Cr(Ⅵ)形成的影响作用。试验结果表明,过氧化二叔丁基能氧化Cr(Ⅲ)成Cr(Ⅵ);抗氧剂1010对Cr(Ⅵ)的生成具有抑制作用,当抗氧剂1010用量为铬质量的10%、反应进行至5h时,Cr(Ⅵ)的含量减少了98.4%。
Di-tert-butyl peroxide was used to simulate the di-alkyl peroxide,produced from the oxidation of leather fat-liquor or grease.At 105 ℃,di-tert-butyl peroxide reacted with solutions of CrCl3,CrCl3-antioxidant1010,respectively.The amount of Cr(Ⅵ) in each solution was measured at different time intervals.The effect of di-alkyl peroxide and free radicals scavenger(antioxidant1010) on Cr(Ⅵ) formation in leather was also explored.The results showed that di-tert-butyl peroxide could oxidize Cr(Ⅲ) to Cr(Ⅵ).antioxidant1010 and inhibit the production of Cr(Ⅵ).When the amount of antioxidant1010 was 10% of the chrome mass and the reaction lasted 5h,the contents of Cr(Ⅵ) in the system of chrome trichloride decreased by 98.4%.
