DITHIODIFORMAMIDINE HYDROCHLORIDE - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | formamidine disulfide dihydrochloride [HN = C( NH 2 ) S] 2 is abbreviated as (formamidine disulfide dihydrochloride) is a chemical reagent widely used in medicine, pesticide, metal plate etching, anticorrosion and organosulfur whitening, etc. It is also a good antiviral drug and fungicide. |
| synthesis method | in a 250 mL round bottom flask equipped with thermometer, magnetic stirrer and constant pressure dropping funnel, 4. 80 g thiourea is first added, 5 mL hydrogen peroxide and 50mL 3 mol /L hydrochloric acid are added into the constant pressure dropping funnel. The flask is cooled in an ice water bath to maintain the reaction temperature in the flask. Under intense stirring, slowly drop the mixed solution of hydrogen peroxide and hydrochloric acid , and control the feeding speed to keep the reaction temperature at about 15 ℃. After the reactants are added, white precipitate is precipitated, stirring is continued, and the reaction is stopped after cooling in ice bath (keeping the reaction temperature at about 3 ℃) 1. 5 h. Add 200mL of anhydrous ethanol and 60mL of concentrated hydrochloric acid, after the dithiamidine hydrochloride is completely precipitated, filter, clean with hot anhydrous ethanol, and vacuum dry at 85 ℃ for 3 h to obtain 4. 34 g of white solid with a yield of 61. 93%. |
