Synthesis and Properties of Precipitating Reagents for Amino Acid
摘要
Abstract
The paper studied the synthesis of 34-dimethylbenzene sulfonic acid,flavianic acid,from some aromatic hydrocarbon or aromatic compounds, which were sulfonated by sulfonic reagents.The relationship betweem the ratio of o-xylene/sulfuric acid and the yield of 34-dimethylbenzene sulfonic acid,and the effect of solvent on the yield of flavianic acid were discussed.The precipitating reagents were quantitavely analyzed by electrolytic titration and UV spectrometry.The paper explored the characters of reaction between two precipitatin reagents and two amino acids (Leucine,Arginine,)respectively,and application the precipitating reagents were used to separate,two amino acids Leucine and Arginine from pig-blood powder hydrolyzate.Experimental results indicated that 34-dimethylbenzene sulfonic acid was a selecting precipitating reagent for Leucine,an other kind was also good.The technology of this precipitating method is simple,the equipment are universal,precipitating reagent can be restored.This method builds up a foundation for large-scale experiment.关键词
