The present invention relates to compounds of formula (I) # imgabs0 # wherein R is a radical selected from linear, branched or cyclic hydrocarbyl groups, optionally comprising one or more heteroatoms, such as oxygen, sulfur, halogen, silicon, nitrogen atoms, and to their use as hydrogen sulfide and/or thiol scavengers in hydrocarbon compositions and water-based compositions, such as water-based drilling fluids. 本发明涉及式(I)化合物#imgabs0#其中R是选自直链、支链或环状烃基的自由基，任选地包含一个或多个杂原子，如氧、硫、卤素、硅、氮原子，还涉及其作为硫化氢和/或硫醇清除剂在烃组合物和水基组合物(如水基钻井液)中的用途。
