WebMercaptans (RSH) are organosulfur compounds that are often present in unrefined or partially refined hydrocarbon feedstocks. These chemicals have several undesirable attributes including strong odor (garlic smell), corrosivity, and degradation of downstream additives as well as the hydrocarbon end products. RSH + R′Br + B → RSR′ + [HB]Br (B = base) Acidity. Thiols are easily deprotonated. Relative to the alcohols, thiols are more acidic. The conjugate base of a thiol is called a thiolate. Butanethiol has a pK a of 10.5 vs 15 for butanol. Thiophenol has a pK a of 6, versus 10 for phenol. 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. … See more Odor Many thiols have strong odors resembling that of garlic. The odors of thiols, particularly those of low molecular weight, are often strong and … See more In industry, methanethiol is prepared by the reaction of hydrogen sulfide with methanol. This method is employed for the industrial synthesis of methanethiol: CH3OH + H2S → CH3SH + H2O Such reactions are conducted in the presence of acidic … See more There are several ways to name the alkylthiols: • The suffix -thiol is added to the name of the alkane. This method is nearly identical to See more Volatile thiols are easily and almost unerringly detected by their distinctive odor. Sulfur-specific analyzers for gas chromatographs are … See more Akin to the chemistry of alcohols, thiols form sulfides, thioacetals, and thioesters, which are analogous to ethers, acetals, and esters respectively. Thiols and alcohols are also very different in … See more
