Adopt the sour deal method right inside the potassium contain measure, the nitrogen contain measure to proceed to measure, and attain fleet, simple, accurate purpose.
采用酸量法对NH4HCO3·xKHCO3( 0
The reaction results indicated that the acid amount corresponding to +0.
3范围内的酸量会影响反应收率,酸量越多,收率越高,得到的聚合产物有合适的数均相对分子质量(700~3000)和较窄的相对分子质量分布(Mw/Mn<2。
As n decreases,the acid amount increases for HPA W·nH 2O with acid stronger than -5 6,but it is almost fixed for HPA W·nH 2O with acid strength less than +3 3.
６的酸量分布产生影响，对酸强度低于＋３。
The results indicated that the incorporated Si acted on the γ-Al_2O_3 to form new bond of Al-O-Si and that the total amounts of acid sites and the acid strength on the surface of γ-Al_2O_3 increased with the amount of introduced Si.
结果显示:引入的硅和γ-Al2O3发生键合形成了新的Al-O-Si键;随着硅的含量增加,γ-Al2O3表面的总酸量及酸强度也增大。
Results showed that the total amounts of acid sites, the acid strength and the proportion of L acid sites increased with increasing the content of Al\-2O\-3.
结果表明：随着Ａｌ２Ｏ３含量增加，Ａｌ２Ｏ３－ＴｉＯ２二元氧化物的总酸量、酸强度和Ｌ酸比例都增加；随着焙浇温度的增大，总酸量下降，Ｌ酸比例和酸强度较大的酸量、百分数则增
