2-Imino-1, 3-dithiopentane is unstable and usually exists in the form of its double salt. The preparation method is in the presence of organic solvents, catalysts and water, carbon disulfide, ethylene oxide and liquid ammonia at 35 to 45 degrees C reaction, the resulting product to remove the solvent, that is, the intermediate product 2-hydroxyethyl dithiocarbamate (ie monoester). Then in the presence of solvent ethyl acetate, dispersant benzene and cyclic agent, monoester isomerization, internal condensation dehydration cyclization, and with acid to form double salt.
