Recall of the preparation method of nickel hexamine salt We have used the classic preparation method, with some modification for avoiding, in certain case, the degradation of the complexes. As a general manner, they are obtained, often around 0 °, by passage of a stream of desiccated ammonia on: a) the simple salt of nickel dehydrated (this is the case for the preparation of 氯化物和硫化物) or hydrated (溴化物，溴酸鹽) or in syrupy mass (thiocyanate) deposited on the wafer of a filter crucible: 多余的水因此被吸干。The nickel salt can be also in concentrated aqueous solution (chlorate) or hydro-ammonia (碘和硝酸); b) on a 堿性鹽, such as chromate; c) on a simple nickel chloride (for the preparation of高氯酸鹽&過硫酸鹽) or on the nickel hydroxide dissolved in the ammonia (preparation of normal 鉬酸&鎢) which we treat, furthermore the ammonia bubbling, by a concentrated solution of ammonium salt corresponding in ammonia. After filtration and wash with alcohol-ammonia, it is appropriate to sweep length by ammonia gas to dry and move resting water presented in the complex cation. The鉻酸鹽 & 過硫酸鹽 should be prepared away from air and be conserved, as well as鎢, in ammonia atmosphere. |
