摘要

the subject of the invention is a method of alkylphenol phosphate reduced trifenylowego phosphate (tpp) of phosphorus oxychloride and) reaction with a mixture of izopropylofenoli (ipf) in the presence of a catalyst, using an ipf to pocl3, and ii) reaction the resulting mixture of phenol, characterised by that the ipf to pocl3 ranges from 1.3 to 1.5.how does not require oddestylowywania pocl3 and controlling composition contains in the final 60 - 75 mpa x s.
