'''乙酸钡'''是钡的[[乙酸盐]]，化学式为<math>Ba(CH_{3}COO)_{2}</math>，有时写作<math>Ba(OAc)_{2}</math>或<math>BaAc_{2}</math>。乙酸钡存在[[无水物]]、一[[水合物]]和二水合物，也能形成酸式盐。<ref>顾学民 等. 无机化学丛书 第二卷 铍 碱土金属 硼 铝 镓分族. 科学出版社, 2011. pp 147. 4.9.2 有机酸盐. ISBN 978-7-030550-3</ref>
==制备==
乙酸钡可由乙酸和[[氢氧化钡]]或[[碳酸钡]]反应得到：
: Ba(OH)<sub>2</sub> + 2 CH<sub>3</sub>COOH → Ba(CH<sub>3</sub>COO)<sub>2</sub> + 2 H<sub>2</sub>O
: BaCO<sub>3</sub> + 2 CH<sub>3</sub>COOH → Ba(CH<sub>3</sub>COO)<sub>2</sub> + H<sub>2</sub>O + CO<sub>2</sub>↑
[[硫化钡]]和[[乙酸]]反应，也能生成乙酸钡：<ref name=hillakomem>[http://www.hillakomem.com/barium-acetate.html Barium acetate] {{Wayback|url=http://www.hillakomem.com/barium-acetate.html |date=20090628101300 }}, hillakomem.com, retrieved 30 June 2009</ref>
: BaS + 2 CH<sub>3</sub>COOH → Ba(CH<sub>3</sub>COO)<sub>2</sub> + [[硫化氢|H<sub>2</sub>S]]

==用途==
乙酸钡可以作为原料，用于制备[[钛酸钡]]<ref>王长文, 沈君权, 膝元成.
