| production method | 1. first prepare hydrochloric acid solution of about 27% with hydrochloric acid with relative density of 1.18, then slowly add iron filings for reaction. When hydrogen is no longer generated, cool, filter, add some small iron flakes washed on the stool surface to the filtrate to prevent chlorination of ferrous chloride, then heat, evaporate and concentrate to the crystalline film, filter while hot, and the filtrate is cooled and crystallized, The following is quickly dried to produce ferrous chloride crystals. Anhydrous ferrous chloride can be prepared by reacting iron and gaseous hydrogen chloride under 900 oC. 2. Ferrous chloride tetrahydrate can be prepared by dissolving iron in hydrochloric acid at a temperature above 12.3 ℃ and under anaerobic conditions. |
