-
Paragraph 0035-0043, (2020/05/05)
The invention provides a method for preparing benzene-1,2-dithiol. The method includes the steps that metal sodium, ethyl mercaptan and 1,2-dichlorobenzene serve as starting raw materials, two halogen atoms of the 1,2-dichlorobenzene are completely substituted in polar solvents N,N-dimethyl formamide by controlling the molecular proportion of the reactants through the high nucleophilic substitution capacity of sodium thioethylate, 1,2-2 ethyl petrol phenyl sulfide is obtained with the high yield, then sulphur atom deprotection is carried out under the reducing action of the metal sodium and naphthalene, and the target product benzene-1,2-dithiol is produced in an almost-quantitative mode after acidizing is carried out through hydrochloric acid. The preparing method is simple, convenient to operate, low in price and high in yield, and has the broad application prospects in the fine chemical engineering and the pharmaceutical industry.
