Method of obtaining phenol and acetone |
| abstract |
FIELD: chemistry. n SUBSTANCE: invention relates to the method of obtaining phenol and acetone by acid-catalysable decomposition of hydro-peroxide of cumene in the environment of the reaction products at elevated temperatures in one stage. In this case the process is carried out in the presence of a catalyst, prepared immediately before its introduction into the reactor for the decomposition of hydro-peroxide of cumene by mixing sulfuric acid with phenol at the ratio of from 2:1 till 1:1000 and the waiting time from mixing till putting into the reactor for the decomposition of hydro-peroxide of cumene from 1 to 600 minutes at a temperature from 20 to 80°C. As a rule, sulfuric acid has a concentration of higher than 75% or oleum is used. n EFFECT: it makes it possible to decrease the output of the by-product hydroxyacetone, improves the quality of market-grade phenol and decreases the consumption of sulfuric acid. n 2 cl, 4 tbl, 4 ex |
