一、基本原理测定有机化合物中鹵素的定量法很多,大多數都是先把有机化合物氧化或还原使其分解鈺r鹵素成游離狀態,或成鹵化氫或兩者的混合物,然後用容量法或重量法測定。在这些方法中,用氧氣流在加熱時氧化有机物的測定鹵素方法比較合於实用。但是它的主要缺點是時間較長,並且需用貴重的鉑催化劑岣叻纸鉁囟群驮黾友鯕饬鞯乃俣?可使有机物的分解加速,並且不需用鉑催化劑欢鴼饬魉俣仍黾又?有机物分解時所生的鹵素及鹵化氫与
First, the basic principles Determination of organic compounds in a lot of halogen quantitative method, most of them are the first organic compounds oxidation or reduction to decompose Yu Yu r halogen into a free state, or into a mixture of hydrogen halide or both, then the volume method Or gravimetric method. Among these methods, the method for the determination of halogens by oxidation of organic substances with oxygen flow on heating is more practical. However, its main disadvantage is that it takes a long time and expensive platinum catalyst is needed to make the decomposition of organic matter faster without the need of a platinum catalyst.魉 俣 still 黾 黾 F?
