化合物(6)上与氮相连的活泼氢原子,可能对某些反应有不利影响,故用碘甲烷对其进行甲基取代,得到了新的手性胍—化合物(7),并做了表征。
The active hydrogen in the compound (6) might take negative effect in some reactions and was substituted by a methyl to get compound (7) which was a new chiral guanidine.
用碱熔法使海带中的碘以i-形式转移到溶液中,然后在酸性条件下用过氧化氢氧化,三氯甲烷萃取,经分光光度标准曲线法测得海带中碘含量大约为426。
I - was obtained from the kelp by alkali fusion, then oxidized by H2O2 in acidic solution, thus we can determine the iodine content by extraction spectrophotometry, which is about 426.
