In this study the preparation of ultrafine powder of Bi2S3 by a reaction between bismuth octanoate and sulfur in organic solvent such as high boiling alcanes is reported. The first step was the preparation of bismuth octanoate. Bi(NO3)3⋅5H2O and octanic acid were used as the starting materials. The acid was reagent and solvent at the same time and was added in twice excess. After boiling the mixture of starting materials during 1  hour, the product was salted out by ethylacetate. The precipitate was filtered and dried in exxicator at room temperature.The second step was the synthesis of bismuth sulfide by boiling of bismuth octanoate and sulfur in decane during 2.5  hours. The dark grey precipitate was filtered and washed with hexane several times to remove the impurites. The product was dried in exxicator at room temperature.

这项研究的超细粉末的反应备Bi2S3辛酸和硫铋等有机溶剂沸腾alcanes高报.第一步是准备铋辛酸.毕(硝酸)3千瓦及octanic锡酸作为原料.酸试剂和溶剂的在同一时间、亮色超过两次.原料混合后煮沸1小时期间,该产品是由腌乙酸乙酯.被沉淀、过滤晒干exxicator在室温第二步是合成的硫化铋铋沸腾辛酸和硫癸在2.5小时.暗灰色沉淀、过滤被己烷洗涤数次以清除impurites.该产品是在exxicator室温干燥
