Abstract
In this experiment,mixed organic acid cobalt was synthesized with cobalt hydroxide,acetic acid,2-ethylhexanoic acid,neodecanoic acid as main raw materials via the neutralization reaction.boronacylate cobalt was synthesized with tributyl borate by acylation reaction.For neutralization reaction,the application of different solvent were studied.In addition,the response surface methodology was used to optimize the molar ratio of neodecanoic acid and 2-ethylhexanoic acid,the quantity of solvent oil and the reaction temperature of acylation reaction to abtain the highest content of cobalt.The optimized synthesis conditions of boronacylate cobalt were obtained with 120# solvent oil as solvent,25.85g solvent for each molar product,0.5185 of the molar ratio of neodecanoic acid and 2-ethylhexanoic acid,the reaction temperature 199.9℃,the optimized cobalt content was 22.4%.
