Research on Katalyst of Mesoporous MnO_2 for Catalytic Oxidation Formaldehyde in Door
室内甲醛催化降解介孔二氧化锰催化剂的研究
The microscale chemical experiment of synthesizing Benzoin was researched. In the experiment vitamin B_1 was katalyst and no-water alcohol was solvent.
采用微型化学实验探讨了制备安息香的方法，即在维生素B1的催化下，用无水乙醇作溶剂经安息香缩合反应制得产品。
In this article, high-pure lactic acid and ethanol acid were used to synthesized PLGA by direct condensation polymerization, and zinc octanoate of low nocuity was used as katalyst, instead of stannous octanoate to synthesize PLGA by the way of opening ring.
本文首次采用高纯度乳酸、乙醇酸直接缩聚合成无催化剂的端羧基PLGA，并分别采用了低毒性辛酸锌代替辛酸亚锡为催化剂通过开环聚合法合成端羧基／酯封端PLGA。
We prepared a stable alkyd emulsion, and research the adding method of dryness katalyst and it's affection on dryness time.
然后，又研究了催干剂的加入方法、催干剂用量对干燥时间的影响，制备出成品醇酸乳胶漆。
