[求助] 纳米二氧化钛的制备已有2人参与

请教各位大牛,我查找到一篇制备纳米二氧化钛的文献,但是对其中的部分操作有些困惑,文中表述如下:A mixture containing 0.5 g sodium hydroxide, 5 ml deionized water, 30 ml oleic acid, 5 ml ethanol, and 1 ml tetra-n-butyl titanate was added to a 50 ml autoclave and reacted at 180 C for 24 h. After cooled to room temperature, the products at the bottom of the autoclave were collected and dispersed in 20 ml cyclonexane. Then 20 ml ethanol was used to precipitate the products, which were further centrifuged at a rate of 12,000 rpm for 10 min. Finally, the products were re-dispersed in toluene with concentration of 0.07 g ml-1。想要请问各位大牛,0.5 g 氢氧化钠,5 ml去离子水,30 ml油酸,5 ml乙醇和1 ml钛酸丁酯的添加顺序是怎样的呢?
