product purity meaning in Chinese
产品纯度
Examples
- For improving product purifying the conditions in recrystallization processes were investigated and a new method for the improving product purity is proposed
结果表明，采用最佳反应条件，可使合成盐酸二甲双胍的产率提高，产品可一次性达到合格标准，找到了提高产品纯度的新途径。 - Using sodium dicyandiamide and saccharin as raw materials , tribenuron - methyl is synthesized via ring - opening reaction , phosgenation and condensation with total yield of 57 . 0 % and product purity of 95 . 6 %
以双氰胺钠和糖精为起始原料，经过开环、光气化、缩合等一系列反应制备了苯磺隆，合成反应的总收率可达57 . 0 %以上，纯度可达95 . 6 %以上。 - When the synthesized acetone cyanamide was first put through a purification treatment and then used for cyanazine synthesis , cyanazine yield was 90 % , while product purity was about 97 % and both quality and yield were consistent across batches
对合成的丙酮氰胺进行精制处理，再用来合成草净津，草净津收率90 % ；纯度可达97 %左右，且各批次的质量和收率都较稳定。 - ( 1 ) in chapter 5 , palladiumphthalocyanine and palladium 4 , 4 ' , 4 " , 4 ' " - tetranitrophthalo - cyanine were synthesized according to condensation method with high yield and high product purity . the structures of products were characterized by element analysis and ir spectra
为此，分别考察了不同引发剂及用量对pvp甲壳糖接枝共聚物的反应性能、接枝分子量、接枝效率以及产物的基本性状等的影响。 - Supercritical co2 fluid extraction exhibits many advantages such as higher extraction yield and product purity , simple production process , lower energy consumption and without solvent residual , but its equipment requirement is high , and it is not easy to realize commercial process
超临界流体萃取法提取率高，产品纯度好，流程简单，能耗低，无有机溶剂残留，但对设备要求高，不易形成工业化生产。
