| titleOfInvention | PROCESS FOR THE PRODUCTION OF HIGH PURITY DIMETHYL CARBONATE. |
| abstract | A process for the production of high purity dimethyl carbonate, comprising: - subjecting at least one commercial grade dimethyl carbonate, which has a chlorine content greater than 1 ppm, to cooling, operating at a fluctuating cooling temperature from + 60C to -5 ° C and at a cooling rate that fluctuates from 0.5 ° C / hour to 2 ° C / hour, to obtain dimethyl carbonate in solid form; - subjecting said dimethyl carbonate in solid form to a first heating, operating at a heating temperature ranging from -5 ° C to + 6 ° C and at a heating rate ranging from 1 ° C / hour to 5 ° C / hour, to obtain a mixture comprising dimethyl carbonate in solid form and a predetermined amount of dimethyl carbonate in liquid form; - separating said dimethyl carbonate in liquid form from said mixture; - subjecting said dimethyl carbonate in solid form to a second heating, operating at a heating temperature ranging from 20 ° C to 40 ° C to obtain dimethyl carbonate in liquid form, said dimethyl carbonate in liquid form having a degree of purity greater than 99.99% and a chlorine content less than or equal to 1 ppm and use the dimethyl carbonate obtained as an organic solvent for the production of the lithium battery electrolyte. |
