Production method of 2-methyl-3(5 or 6)-methylthio pyrazine

The invention discloses a production method of 2-methyl-3(5 or 6)-methylthio pyrazine. The method comprises the following steps: adding solvents dichloroethane and triethylamine into a reaction kettle, sealing the reaction kettle, introducing chlorine to control the pressure in the kettle at 0.02-0.03 MPa, pumping a methylpyrazine solution into the reaction kettle by using a metering pump, controlling the temperature at 45-60 DEG C, reacting, and transferring reaction liquid(containing the chlorine)in the kettle into a dichloroethane turnover tank through filter pressing for recycling after the reaction is finished; dissolving the residual 2-methyl-3(5 or 6)-chloropyrazine hydrochloride solid in the reaction kettle with water, adjusting the neutrality, and layering to obtain a 2-methyl-3(5or 6)-chloropyrazine crude product; and dropwise adding thechloropyrazine crude product is into sodium methyl mercaptide, performing reflux reaction , and after reaction liquid is extracted, adding an aid into an organic phase to generate a hydrochloride for separating the non-pyrazine product from the product to greatly improve the aroma quality of the obtained product. The product grade is improved, and the whole production process is safe and environmentally friendly.
