| titleOfInvention | PROCEDURE FOR THE PREPARATION OF SULFURIC ACID SEMIESTERS OF OXALCOHYLATED ALCOHYLPHENOLS OF VARIOUS NUCLEES. |
| abstract | Process for the preparation of sulfuric acid half esters of oxalcohylated alkylphenols with several nuclei of formula I **formula** in which-(OX)- means oxalcohylene radicals with 2 to 3 carbon atoms in the alkylene chain, R1 means a straight or branched chain saturated alkyl radical with 1 to 14 carbon atoms, Y means hydrogen or the SO3Me radical, Me means hydrogen, the ammonium ion, an alkali metal ion or an equivalent of an alkaline earth metal ion, and n and m represent numbers from 2 to 25 and z represents numbers from 1 to 9, characterized in that monoalcohilphenols of the formula II **formula** in which R1 has the above meanings are condensed with formaldehyde in the molar ratio of 2:1 to 10 :9 in the presence of acid catalysts to form polynuclear novolac resins, these are reacted in the presence of alkaline catalysts with 2-25 moles of alkylene oxide for each mole of alkylphenol used, and The free hydroxyl groups of the oxalcohylates obtained are reacted totally or partially with sulfating agents to form the half esters of sulfuric acid and eventually in the aqueous phase to form the alkali metal, alkaline-earth metal or ammonium salts of the half esters of sulfuric acid of formula I |
