发明名称 Malachite preparation
摘要 Synthetic malachite of desirable particle size and distritution is coprecipitated with small amounts of uniformly dispersed bismuth. After nucleation, the crystals are grown at elevated temperatures. The malachite can be converted into a cuprous acetylide complex useful as an ethynylation catalyst.
