B. Solution-Liquid-Solid Growth of Indium Phosphide Fibers from Organometallic Precursors: Elucidation of Molecular and Nonmolecular Components of the Pathway
Solution-phase organometallic syntheses of semiconductors are used for the growth of high-quality quantum dots,1-3 and are potentially useful for the deposition of semiconductor materials on thermally sensitive substrates such as polymers
In synthetic luminol process we need luminol’s precursor. That is
5- nitrophthalhydrazide. It is synthesized by the reaction of 3-nitrophthalic acid
with hydrazine. This process is condensation reaction. First, hydrazine(N2H4) is
heated with the 3-nitrophthalic acid. This reaction is most conveniently carried
out in the high-boiling solvent triethylene glycol. To boil off excess water, t

The luminol is activated with an oxidant. Hydrogen peroxide solution and sodium hydroxide is
used as the activator. In the presence of an catalyst, the hydrogen peroxide is decomposed to form
oxygen and water. The iron in potassium ferricyanide is a catalyst for the reaction.
When luminol reacts with the sodium hydroxide, a dianion is formed. The oxygen produced from
the hydrogen peroxi
Ⅰ. 다이옥신의 역사
다이옥신이 처음으로 합성된 것은 1872년의 일이다. 다이옥신은 무엇에 사용할 목적으로 공업적으로 합성된 일은 없다. 문제는 다이옥신이 다른 물질을 합성하거나 폐기물을 소각하는 과정에서 의도하지 않았음에도 발생한다는 점에 있다. 화학품 2,4,5-TP(트리클로로페놀,trichloroph
