We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

在实验室条件下，通过APV静态热解制备了粉状五氧化二钒，研究了静态中温条件下氨的脱除、钒的价态变化，以及硫、硅、钾、钠等主要杂质在产物中的含量与温度及时间的关系。

The B. light touches the intermediary is one catalyst, itself does not consume, the essential component is a nanometer carbon dioxide (TI02), under the illumination, Shui who the light touches in the intermediary union air He the oxygen forms the strong oxidized in the surface oxyhydrogen free radical, can decompose in the air the noxious gas and the bacterium, and releases C02 and the water, achieves the sterilization, the air purification, to deodorize.

B。 光触媒是一种催化剂，本身并不消耗，主要成份是纳米二氧化碳（ TI02），在光照下，光触媒结合空气中的水和氧气在表面形成强氧化性的氢氧自由基，能分解在空气中的有害气体和细菌，并释放出 C02和水、达到杀菌、空气净化、除臭。

9Random cent is 0 bandicoot 6 groups, contrast except blank outside the group, the others all combines anhydrous alcohol fill 5 groups to take with natrium of deoxygenate cholic acid undertake CAG builds a model.
