Sterically hindered N-methylsecondary and tertiary amine sulfur scavengers and methods for making and using same
摘要：
An new class of oil-soluble, sulfur scavengers or converts are disclosed where the scavengers include substantially monomeric aldehyde-amine adducts from the reaction of at least one sterically hindered primary or secondary amine and a molar excess of at least one aldehyde. Methods are also disclosed for reducing, reducing below a given level or eliminating noxious sulfur species from fluids using the inventive scavengers and for making the inventive scavengers.
摘要（中）：

公开了一类新的油溶性硫清除剂或转化剂，其中清除剂基本上由至少一个空间位阻伯胺或仲胺与摩尔过量的至少一种醛的反应包含单体醛 - 胺加合物。 还公开了减少，降低到低于给定水平或使用本发明的清除剂从流体中消除有毒硫物质并用于制备本发明的清除剂的方法。
