固相和液相法合成氰尿酸的對比研究 |
朱文明(常州工程職業(yè)技術(shù)學(xué)院應化系; 江蘇常州) |
摘 要:對固相法和液相法合成氰尿酸的方法進(jìn)行比較,采用比色法測定縮二脲含量,用甲醛測定尿素、縮二脲的總氮量,由縮二脲的含量、總氮量推算出尿素的含量及產(chǎn)品的純度,從而說(shuō)明液相法的優(yōu)勢。以不同溶劑加熱脫氫生產(chǎn)氰尿酸的收率和純度做了對比實(shí)驗,并通過(guò)選擇確定硅油210 50是一種新型的理想的和廉價(jià)的溶劑。 |
關(guān)鍵詞:氰尿酸; 固相法; 液相法; 溶劑 |

The Contrast of Solid and Liquid Hromatography to Synthesize Cyanuric Acid |
ZHU Wen-ming ( Changzhu Institute of Engineering Technology; Changzhou 213004; China) |
Abstract:The ways for synthesizing cyanuric acid by solid and liquid chromatography were compared. The content of biuret by colorimetry and the total content of nitrogen in urea and biuret were mensurated. Then,some contrastive experiments on producing cyanuric acid by heating up different kinds of solvent to eliminate hydrogen were done. According to the contrastive results of the collection rate and the purity of cyanuric acid, the silicone oil 210-50 is not only a new and perfect, but also a kind of cheap solven... |
Key words:cyanuric acid; solid chromatography; liquid chromatography; solvent |
