The capture and conversion of H₂S is of importance towards long-standing economic and environmental challenge. Hence, a series of task-specific ionic liquids were developed and presented as both absorbents and catalysts for simultaneous capture and conversion of H₂S into high valuable mercaptan acids using unsaturated acids as starting materials. Good to quantitative conversion was realized with catalytic loading of ILs. Water extraction was employed to separate the product from the reaction system. The kinetic isotherm demonstrated that the addition reaction can achieve 98% conversion at 90 °C and 50 mol% of catalyst loading within 1 h. A plausible reaction-separation-integration strategy was further proposed. This work discloses a green, simple, and mild but effective method for the capture and catalytic conversion of H₂S into high valuable mercaptan acids.

H ₂ S的捕获和转化对长期的经济和环境挑战至关重要。因此，开发了一系列特定任务的离子液体并将其作为吸收剂和催化剂同时用于H _2的捕获和转化使用不饱和酸作为原料将S转化为高价值的硫醇酸。IL的催化负载实现了良好的定量转化。采用水萃取将产物与反应体系分离。动力学等温线表明，加成反应可在90°C下实现98％的转化率，并在1小时内达到50 mol％的催化剂负荷。进一步提出了可行的反应-分离-整合策略。这项工作公开了一种绿色，简单，温和但有效的方法，用于将H ₂ S捕获并催化转化为高价值的硫醇酸。
