esterase

In the process of the synthetic experiment with the pearlizer , the researchers focus their efforts on the exploration of the following areas concerning the artificial pearliser : ( 1 ) the material ratio ( 2 ) the amount of the catalyst used ( 3 ) the effect of such technological conditions as temperature and time on the performance of the final product , and ( 4 ) the ester value , acid value , yield rate , and appearance 在這次珠光劑的合成實驗中,我們主要從以下凡個方面進行了探索研究工作: ( 1 ) (探索了珠光劑合成的)原料配比. ( 2 ) (探索了珠光劑合成的)激活劑用量. ( 3 ) (探索了珠光劑合成中的)溫度、時間等合成工藝條件對產品性量的影響. ( 4 )探索了酯值,酸值、產率、外觀等。
