The TaKoii method has the following disadvantages: the difficulty of creating mono-airatates for schloflorine, and Enla ciiCTa killed (.t and | 1oi rationally to the square of the source; insignificantly 11) the transparency of the reaction mixture drastically reduces fopch) chemical effect; The irradiation system of the environment enrichment ion increases the explosion (explosion) and is} 1 and the herodess (n) the light shafts must be enclosed in an explosion-proof valve), which complicates the maintenance of the animatant; In photochemical sulfochlorination, the process is chlorination of a yenn-thrombone and a gamma (for analysis, the chlorine content is 29%, sulfur is 1.5-2%).

С целью уст|)анеии  указанных недостатков предлагаетс  is качестве ин1н.1,иаторов примен ть органические оксииерекиси, нанример диоксннерекнсь хлорал  или нерекись оксиметил-г/ ег-бутила .

The use of these initiators makes it easy to regulate the sulfochlorination process and to obtain products with a given amount

And the most irrective is the concentration of H1; it is 3-5% of the co-concentration of polyethylene in an indifferent solvent (carbon tetrachloride) and 45 ° C. Under these conditions, the reaction medium is a homogeneous solution, which has a favorable effect on the course of the process. The more coherent | 5a solution is presented with a decrease and the sulfochlorination for a longer time with all other conditions being equal. For carrying out the reaction, one can use Kaiv devices of a single-phase pump. so n round-bottom reactors. It should be noted, however, that in the case of a photochemical initiating sulfonated chlorine monoxide, especially in round-bottom reactors, it is very difficult. Offered for the supply of oxinereoxide is generally available and free of solvents; dyes, especially in organic solvents (including tetrachloro carbon).
