METHOD OF PRODUCING TERT-BUTYLHYPOCHLORITE Russian patent published in 2012 - IPC C07C71/00 

FIELD: chemistry.

SUBSTANCE: invention relates to an improved method of producing tert-butylhypochlorite which is an effective oxidant and a "soft" chlorinating agent. The method of producing tert-butylhypochlorite involves reaction of tert-butyl alcohol with chlorine in an alkaline medium, where tert-butyl alcohol and chlorine are added to a freshly prepared sodium hypochlorite solution with concentration of 8.0-18.0 wt %, with pH of the solution not less than 10, or tert-butyl alcohol is added directly during preparation of sodium hypochlorite solution through chlorination of aqueous sodium hydroxide solution, chlorine is continuously added until after batching tert-butyl alcohol and until attaining pH of the reaction mixture of 4.8-5.5. Aqueous sodium hydroxide solution with concentration of 10-23 wt % is used to obtain sodium hypochlorite solution. Excess chlorine released at the end of synthesis of tert-butylhypochlorite is absorbed with an aqueous alkaline solution to form sodium hypochlorite which is returned into the cycle for subsequent synthesis of tert-butylhypochlorite.

EFFECT: obtaining end product with high output in commodity form.
