'''三甘醇'''，结构式HO(CH<sub>2</sub>CH<sub>2</sub>O)<sub>2</sub>CH<sub>2</sub>CH<sub>2</sub>OH。

==性质==
无色几乎无臭吸湿性粘稠液体，可燃。与水和[[乙醇]]混溶，微溶于[[乙醚]]，几乎不溶于[[石油醚]]。毒性极低，未见中毒病例。<ref name="zghg" />

==制备==
三甘醇是通过[[环氧乙烷]]水合制取[[乙二醇]]时的副产物，由[[二甘醇]]继续与环氧乙烷反应得到。
:<math>\ H_2C(O)CH_2+HOCH_2CH_2OCH_2CH_2OH\rightarrow </math><math>\ HOCH_2CH_2OCH_2CH_2OCH_2CH_2OH</math>
