The synthetic route starts from penicillin G, peroxyacetic acid(8.5%) as Oxidizing Agent to get penicillin G sulfoxide; esterifided with p-nitrobenzyl bromine to synthesize penicillin G sulfoxide ester; we synthesize 3-exomethylenecepham sulfoxide ester with phthalimide potassium and 4A molecular sieve as acid scavenger to open the ring, SnCl_4 as catalyzation to close the ring. The yield is over 60%.

本研究采用的合成路线为：以青霉素G钾盐为原料，选用工业过氧化氢制备的过氧乙酸(22.3%)稀释至8.5%为氧化剂，氧化得青霉素亚砜；采用对硝基溴苄为酯化试剂，制备青霉素亚砜酯；以NCP(N-氯代邻苯二甲酰亚胺)为开环试剂，酞酰亚胺钾和4A型分子筛为酸清除剂，顺利开环；再经无水SnCl_4催化闭环得3-环外亚甲基头孢亚砜酯，最终产率在60%以上。

Therefore, strengthening domestic potassium salt mining and usage, encouraging overseas partners to explore overseas potassium salt resources and set up potassic production base is an important way to solve domestic shortage of potassic fertilizer.

Acceptable resolutions were achieved when it was applied for the separation of dipeptides including Leu-Tyr and Val-Tyr by using 1-butanol-acetic acid-water (4:1:5, V/V/V) solvent system. The proteins including cytochrome C and myoglobin, lysozyme and myoglobin, and fresh chicken egg-white proteins were well separated by 12.5% PEG1000-12.5% K2HPO4-75% water (pH 9.0) and 16% PEG 1000-12.5% K2HPO4-71.5% water (pH 8.0) system.

应用研究表明，采用正丁醇-醋酸-水(4：1：5， V/V/V)和PEG1000-磷酸钾盐-水(12.5：12.5：75， W/W/W)(pH 9.0)体系可以在较高的流动相流速和较高的固定相保留下分别实现对亮氨酸-酪氨酸和缬氨酸-酪氨酸二肽混合物以及细胞色素C与肌红蛋白、肌红蛋白与溶菌酶混合物及鸡蛋清样品中蛋白成分的成功分离。
