1) solution of acid with enthanol
醇-酸体系
1.
The spectrum of the tetraphenylporphine substituents and its derivatives were studied in the solution of acid with enthanol.
研究了四苯基卟啉类光敏剂在醇-酸体系中的光谱性质,以及在此体系中浓度、酸度、表面活性剂等因素对其光谱性质的影响,首次发现在醇-酸体系中四苯基卟啉类光敏剂的光谱性质发生改变,靠近红外区均有中强度吸收,它们在可见光波长的激发下能产生在近红外区的荧光峰,与硫酸比较而言,盐酸配制的醇-酸体系优于硫酸体系。
2) Perchromic acid-pentanol system
过铬酸-戊醇体系
3) ethanol/ammonium sulphate system
乙醇/硫酸铵体系
4) sulfuric acid-phosphoric acid-glycol system
硫酸-磷酸-乙二醇体系
5) sec-butanol-water-K_2CO_3 system
仲丁醇-水-碳酸钾体系
1.
In this paper,the data about the liquid-liquid equilibrium(LLE) of sec-butanol-water-KF and sec-butanol-water-K_2CO_3 systems are measured at 25℃,showing that the sec-butanol phase contains negligible salt and the water phase contains negligible sec-butanol when the mass fraction of KF or K_2CO_3 in the water phase is not less than 26.
文中通过实验测定了仲丁醇-水-氟化钾、仲丁醇-水-碳酸钾体系在25℃时的液-液相平衡数据,发现当水相中氟化钾或碳酸钾含量分别大于或等于26。
6) formic acid-methanol-urea Cr(Ⅲ) plating system
