Synthesis of amino diphenyl ethers by na2s reduction
卤代氨基二苯醚的合成研究
The corrosion behaviors of hot - dipping aluminium steel in na2s solution
溶液中的腐蚀行为研究
Ab initio study of structures for li2o , li2s , na2o , na2s molecules
碱金属氧化物和硫化物分子结构的从头算研究
Determination content of na2s with the use of precipitation separation - complexmetric titration
络合滴定法测量硫化钠含量
2m / 1 , the concentration of na2s is 0 . 1m / l , the temperature of sncl2 solution is 70c and na2s is room temperature
氯化亚锡溶液的反应温度是70 ，硫化钠溶液的反应温度是室温。
Moreover , in our work , it was found that the pbs nanoparticles were formed by using other sulfur source or a ph value less than 7 in the hydrothermal method . when using pbso4 and na2s as reactants , the autoclave was maintained at 200c for 20h , the products were pbs nanorods
以醋酸铅和硫脲为先驱体， ph值大于10 ，在200下反应24小时，是制备pbs星状结构的最佳条件；改变硫源或体系ph值小于7时，所得产物均为pbs纳米颗粒。
