摘要

多羟基醇如丙三醇、乙二醇、聚乙二醇等富含氢键位点，通过氢键相互作用能循环捕集SO

气体。然而，羟基比例更高的丙三醇和乙二醇对SO

的吸收能力远弱于聚乙二醇，这表明除氢键作用之外，可能还存在SO

与醚氧原子间的电荷转移作用。为了证实SO

与醚氧原子间的电荷转移作用，实验选择沸点较高的三乙二醇二甲醚作为SO

的吸收剂。首先采用气体动态单循环法测定了低浓度SO

（体积分数为2010 × 10

-6

）在122.7 kPa和293.15~313.15 K下的汽液相平衡数据，并且基于汽液平衡数据，计算了SO

吸收过程的热力学参数，包括亨利常数、熵变、焓变和Gibbs自由能等。此外，基于紫外光谱、红外光谱和核磁波谱的实验结果，证实了SO

和三乙二醇二甲醚之间的O…S电荷转移相互作用。

Abstract

Polyhydric alcohols such as glycerol

ethylene glycol

polyethylene glycol

etc

are rich in hydrogen bonded sites and can trap SO

gas cyclically through hydrogen bond interactions. Although both glycerol and ethylene glycol have more hydroxyl groups than polyethylene glycol

the absorption capacity of SO

is lower than that of polyethylene glycol

which indicates that in addition to the hydrogen bonding effect

there may be a charge transfer effect between SO

and ether oxy

gen atoms of polyethylene glycol. Herein

to clarify the charge transfer effect between SO

and ether oxygen atoms

triethylene glycol dimethyl ether with a higher boiling point was selected as SO

absorbent. First

the gas-liquid equilibrium data of diluted SO

(2010 × 10

-6

) at 122.7 kPa and 293.15 to 313.15 K were measured by a gas dynamic single cycle method. Then the thermodynamic parameters of the absorption process were calculated based on the SO

solubility data

including Henry

􀆳

s constant

entropy change

enthalpy change and Gibbs free energy. In addition

the O…S charge transfer interaction between SO

and triethylene glycol dimethyl ether was confirmed by using UV-Vis

FTIR and NMR spectroscopy.
