The distinctive smell is caused by the presence of triethylamine. Even a small amount of TMA, slightly above 50 ppb, can give the entire product its characteristic odor. Despite the odor, the product can still be used.

Why on occasion does Product 34860, Methanol, have an unusual odor? Does it affect the product purity or performance?
1 回答-
Industry research has indicated that unusual odors in methanol are a common problem and stem from low - level mercaptans and / or amines found in the natural gas raw materials used in production. Odors from these types of compounds can be noticeable at low part per million (ppm) levels and have not been shown to have any negative impact on product performance at these concentrations.
