Abstract: The payable production process of CrCl₃·6H₂O is a reduction method with using chromic anhydride.It has many disadvantages，such as high cost，heavy pollution，and cockamamie process flow.The chromium（Ⅲ） chloride hexahydrate was prepared by sodium chromate directly.The influences of maturation time，quantity of hydrochloric acid，reductant，and its quantity on reaction effect were investigated.Results showed that when maturation time was 4 h，reductant was methanol，the quantity of hydrochloric acid was 1.5 times as great as theory quantity，the quality of chromium（Ⅲ） chloride hexahydrate could meet the quality requirement of professional premium grade of industry standard，and the cost can be decreased greatly amplitude as the cost of preparation by chromic anhydride.
