Chemical reagent& Potassium hydrogen phthalate GB/T1291-1988化学试剂邻苯二甲酸氢钾
Studies on Standard pH Reference Values of Potassium Hydrogen Phthalate in Isopropanol Water Solvent Mixtures 邻苯二甲酸氢钾在异丙醇-水混合溶剂中标准pH参考值的研究
Acetanilide and hexane diacid, potassium hydrogen phthalate could improve PVC crystallinity. 乙酰苯胺、己二酸和邻苯二甲酸氢钾可以使PVC结晶度增大。
The results are found that: ( 1) COD which potassium hydrogen phthalate and glucose samples were heated in 1 minute by microwave digestion coincided with that in 2 hours by heater according to international standard ISO 6060-1986. The recovery ratios were both 96%. 结果表明:(1)微波加热1min后,测得邻苯二甲酸氢钾和葡萄糖水样的COD值与采用ISO6060-1986国际标准测得COD值基本一致,COD的回收率都达到96%以上;
A wavelet packet transform latent variable regression ( WPLVR) method was developed to perform simultaneous determination of methyl salicylate ( MSA), dibutyl phthalate ( DBP) and potassium hydrogen phthalate ( PHP) in their mixture. 采用小波包变换潜变量回归(WPLVR)方法,同时测定水杨酸甲酯(MSA)、邻苯二甲酸二丁酯(DBP)和邻苯二甲酸氢钾(PHP)。
Potassium hydrogen phthalate could also provide base for the array of fold chains, so it promoted the development of chain-folded crystal as well. 邻苯二甲酸氢钾也能为折叠链排列提供基底,因此也能促进折叠链状晶体的生长。
