2-methylpropane-1-thiol can be used as an analytical reagent. The bromoisobutane is prepared by the following steps. With methanol as the solvent, thiourea and bromoisobutane were refluxed for 4-5h. After methanol was recovered, lye was added and refluxed for 4h, dilute acid was added to acid. Isobutyl mercaptan was evaporated with Chemicalbook until it was no longer steamed. Separate the water layer. After drying the oil layer with anhydrous magnesium sulfate, separate the desiccant and carry out fractionation. Collect the fraction of 85-86℃ for the finished product.
