Method for eliminating polymerisation inhibitors of monomer mixtures including tert-butylcatechol |
| abstract |
The present invention relates to a process for the preparation of a composition comprising extracting a tert-butyl catechol by dissolving a mixture comprising a tert-butyl catechol containing polymerization inhibitor and at least two ethylenically unsaturated monomers in a sodium hydroxide solution, Wherein the sodium hydroxide solution is injected by a sparger dispersion method, a spray dispersion method, or a direct injection method, and the sodium hydroxide solution is injected into the aqueous solution of sodium hydroxide Is 1% by weight to 20% by weight, and 10-20 parts by weight of the sodium hydroxide solution is dissolved in 100 parts by weight of the mixture. |
