Web11.9.1.1 Caustic Processes. The hydrocarbon processing industry has historically used caustic solutions to extract or treat acidic impurities (mainly RSH) in hydrocarbon liquid streams. When quantities of acid gas contaminants are small (e.g., less than 200 ppmwt), a simple caustic wash is effective and economical.

This explains the tendency of thiols to bind to soft elements and ions such as mercury, lead, or cadmium. The stability of metal thiolates parallels that of the corresponding sulfide minerals. See more In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group … See more Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols. Thiols and alcohols have similar connectivity. Because sulfur atoms are larger than oxygen atoms, C−S bond lengths – … See more Volatile thiols are easily and almost unerringly detected by their distinctive odor.
