  1. And the value drop to the lowest at ph = 0. 8. as the increase of heat treatment temperature, the pore size distribution peak of sio2 microspheres is very narrow, meanwhile the specific surface area is the smallest before 160 c. the polymer template is removed at 350 c, so the pore structure of sio2 particles has a big change which involve the increase of specific surface area and the broaden of pore size distribution peak. with the continuous raise of temperature the sio2 network will shrink little, as a result the average pore size will decrease, but the specific surface area has no obvious change

    結果發現:二氧硅膠體顆粒均勻分佈於脲聚合物網路中,煅燒去除有機模板后微球表面變粗糙,而粒徑沒有明顯變; ph值較小時,復合微球中聚合物含量較大,而ph值較大時,得到復合微球結構鬆散,因此熱處理后的二氧硅微球孔容及平均孔徑都較大,而在ph = 0 . 8時,得到最小值;武漢理工大學碩士學位論文隨著熱處理溫的變,小於160時,空分佈較窄,而比表面積較小,在350時,由於有機模板的去除,微球孔結構發生突變,比表面積明顯增大,而孔徑分佈變寬,溫繼續升高時,二氧硅網路發生收,平均孔徑變小而比表面積由於有機炭物的完全去除沒有太大變;微球中的微孔在熱處理過程中處于平衡狀態,分佈沒有太大變
  2. In the course of oxidation, reaction temperature should rise step by step, and in the late stage, reduced pressure distillation should follow so that the concertration of glyoxalic acid can rise and production rate of allantoin can rise up to 40 %

    在氧反應的過程中逐步地提高反應溫,反應後期進行減壓濃,提高了乙酸的濃短了氧時間,並使尿囊素產率達到40 % 。
