It is also used to obtain tertiary butyl hydroperoxide (TBHP) by reaction with hydrogen peroxide.
Physico-chemical properties
The 2-methyl-2-propano l is a colorless solid, which melts at near room temperature (25-26 ºC) and has a camphor-like odor. It is miscible in water, ethanol and diethyl ether. Its boiling point is 82-83 ºC and its density is 0.775 g-mL −1 .
Method of production
Terbutanol is obtained commercially from isobutane as a by-product of propylene oxide production. It can also be produced by catalytic hydration of isobutylene, or by a Grignard reaction between methyl magnesium chloride and acetone.
What is the rate constant for a vapor phase reaction of t-butyl mercaptan
The rate constant for the vapor-phase reaction of t-butyl mercaptan with photochemically-produced hydroxyl radicals is 3.31X10-11 cu cm/molecule-sec at 25 °C (SRC) using a structure estimation method (1). This corresponds to an atmospheric half-life of about 12 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (1). Other experimental rates constant for the vapor-phase reaction of t-butyl mercaptan with photochemically produced hydroxyl radicals were measured as 2.9X10-11 (2) and 3.51X10-11 (3) cu cm/molecule-sec at 25 °C, corresponding to half-lives of 13.3 and 11.0 hours, respectively, based on a hydroxyl radical concentration of 5X10+5 (1). t-Butyl mercaptan is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups (4). t-Butyl mercaptan is difficult to convert to the disulfide or oxidize to the sulfonic acid under normal environmental conditions (5). t-Butyl mercaptan does not absorb light at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight.
What is a CAS number for t-butyl mercaptan?
T-butyl mercaptan (CAS # 75-66-1) was evaluated for subchronic inhalation toxicity. The test substance was administered to rats (15/sex/group, strain not reported) at concentrations of 0 ppm, 9 ppm, 97 ppm, or 196 ppm for 6 hours/day, 5 days/week for 13 weeks. At 9 ppm, histopathology indicated inflammatory lesions in the lungs. At 97 ppm, minimal to mild interstitial fibrosis was indicated. At 196 ppm, interstitial fibrosis in the lungs of males and females, and nephrosis in male rats only was indicated.
How is t-butyl mercaptan released?
t-Butyl mercaptan's production and use as an odorant in natural gas, as an intermediate, and as a bacterial nutrient may result in its release to the environment through various waste streams. If released to air, an extrapolated vapor pressure of 181 mm Hg at 25 °C indicates t-butyl mercaptan will exist solely as a vapor in the ambient atmosphere. Vapor-phase t-butyl mercaptan will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 12 hours. t-Butyl mercaptan does not absorb light at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, t-butyl mercaptan is expected to have very high mobility based upon an estimated Koc of 49. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 6.1X10-3 atm-cu m/mole. t-Butyl mercaptan may volatilize from dry soil surfaces based upon its vapor pressure. If released into water, t-butyl mercaptan is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Biodegradation data were not available. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 3 hours and 4 days, respectively. An estimated BCF of 9 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to t-butyl mercaptan may occur through inhalation and dermal contact with this compound at workplaces where t-butyl mercaptan is produced or used. Use data suggest that general population exposure may occur via inhalation of ambient air near natural gas refineries and operations due to use as a natural gas odorant. (SRC)
What are the most common methods of synthesis of thiols?
Thiols can be prepared by a variety of methods. The most-utilized of these synthetic methods for tertiary and secondary thiols is acid-catalyzed synthesis; for normal and secondary thiols, the most-utilized methods are free-radical-initiated, alcohol substitution, or halide substitution; for mercaptoalcohols, the most-utilized method is oxirane addition; and for mercaptoacids and mercaptonitriles, the most-utilized methods are Michael-type additions. /Thiols/
What enzyme catalyzes the formation of mixed disulfides?
Both microsomal and cytoplasmic thioltransferasess have been reported to catalyse the formation of mixed disulfides. The resulting mixed disulfides can undergo reduction back to thiols, oxidative desulfuration, or oxidation to a sulfonic acid via the intermediate thiosulfinate and sulfinic acids.
Where is the methylation system located?
Enzyme system responsible for conversion of endogenous toxic mercaptans in nontoxic thioether products via methylation is located in endoplasmic reticulum. Methylation of thiols studied was minimal in kidneys and brain, high activity seen in lungs. /Mercaptans/
Is t-butyl mercaptan a bacterial nutrient?
t-Butyl mercaptan's production and use as an odorant in natural gas, as an intermediate, and as a bacterial nutrient (1) may result in its release to the environment through various waste streams (SRC).
