| titleOfInvention | Method of purifying chloroform |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of purifying chloroform through its treatment with a mixture of gaseous sulphuric anhydride with air, obtained by passing air through oleum heated to temperature 30°C-60°C. Treatment is carried out at temperature 20°C-50°C for 2-7 hours and content of sulphuric anhydride in the gaseous mixture of 20-50 wt %. n EFFECT: obtaining high-quality chloroform, in which not only 1,1-dichloroethane is absent, but cis- and trans-dichloroethane as well, considerable reduction of waste water and gaseous emissions, reduction of raw material consumption. n 1 cl, 1 ex, 3 tbl |
