The experimental results shows, if the ratio between MS-1 and OP-10 rangs from 1:1 to 3:l,and the total dosage of them is about 20% of Octamethylcyclotetrasiloxane (D4 ) in quality, we can obtain a kind of stable seeded emulsion of organic silicone modified acrylic ester emulsion. At the same time, if the ratio between MS-1 and Tetramethylammonium Chlorideis l:1.7,the total dosage is about 50% of D4 in quality; the ratio between MS-1 and Cetyltrimethylammonium Chlorineis 7:1, the total dosage is about 25% of D4 in quality,we can also obtain stable seeded emulsions. But if the complex emulsifier system is made of TMAC and OP-10, MS-1 and Peregal O or CTAC and Span-80, we can not synthesize any kind of satisfactory seeded emulsions.

The effects of solution\'s pH value, mol ratio between phenyl aldehyde and L-Arginine, concentrations of sodium chloride, ammonia chloride andL-Lystine, initial concentration of L-Arginine on precipitation rate of a -tolylene arginine were investigated, the results indicated that phenyl aldehyde precipitation method\'s appropriate pH value was higher than 11, suitable mol ratio between phenyl aldehyde and L-Arginine was 1.25, initial concentration of L-Arginine was must higher than 15g/L, sodium chloride had little effect on precipitation rate, on the contrary, ammonia chloride and L-Lystine had great effect on it, both of them must be eliminated; At the same time, adsorption isotherm at 25 C of L-Lystine on anion exchange resin A was measured, the result showed that the maximal equilibrium adsorbance was 30mg/g, the influences of solution\'s pH value, temperature, concentration of chloride ion on adsorption of L-Lystine by anion exchange resin A were also studied, the results indicated that appropriate operational pH value was 0.5 0.2, the effect of temperature on adsorption ratio was little, process could be operated at room temperature, the concentration of chloride ion must be eliminated.

考察了溶液pH值、苯甲醛与L-精氨酸摩尔比、氯化钠与氯化铵浓度、L-赖氨酸浓度、L-精氨酸初始浓度对苯甲醛沉淀L-精氨酸的影响，结果表明，沉淀反应的适宜pH值大于11，苯甲醛与L-精氨酸的适宜摩尔比为1.25，(来源：Aa6BC论文网www.abclunwen.com)L-精氨酸适宜的初始浓度在15g/L以上，氯化钠的存在对沉淀率基本上没有影响，而氯化铵和L-赖氨酸的存在使沉淀率下降；同时测定了25℃时阴离子交换树脂A吸附L-赖氨酸的吸附等温线，表明其最大平衡吸附量为30mg/g，考察了溶液pH值、温度、氯离子浓度对阴离子交换树脂A吸附脱除L-赖氨酸的影响，结果显示从L-精氨酸和L-赖氨酸混合液中吸附分离出L-赖氨酸的适宜pH值为10.5±0.2，温度对L-赖氨酸吸附率影响不大，吸附过程可在室温下进行，氯离子的存在使L-赖氨酸的吸附率降低。
