    Abstract: An improvement in the liquid phase air oxidation process based upon a solvent system such as acetic acid and with a bromine activated heavy-metal catalyst system for preparing phthalic, isophthalic and terephthalic acids from their corresponding alkyl benzenes wherein the heavy metal is a soluble cobalt compound and sufficient excess of air is introduced so that the waste gas still contains an excess of oxygen.

    Abstract: p-tert-octyl phenol is produced by reaction of phenol with diisobutene in the presence of an acidic ion exchanger and water, in a first stage, in a solid-bed reactor at temperatures of 110.degree.-140.degree. C. and under an excess pressure of up to 5 bar. The resultant dioctyl phenol formed as a by-product is alkylated in a second stage in a further solid-bed reactor with phenol in the presence of an acidic ion exchanger, and water at temperatures of 110.degree.-140.degree. C. and under an excess pressure of up to 5 bar to obtain additional p-tert-octyl phenol.

    Abstract: In a process for the manufacture of a p-alkylphenol by alkylating phenol with an olefin of 3 to 4 carbon atoms, at an elevated temperature, in the liquid phase, in two reaction zones in series and in the presence of a strongly acidic ion exchange resin as the catalyst, an improvement comprises:(a) passing in a first reaction stage at a temperature of 80.degree.-140.degree. C. over a suspended catalyst, the olefin as a gas at a gas velocity of 30 to 20 cm/second, based on the free cross-section of the empty reactor and on a molar volume of 25 liters per mole of olefin, from below into the reaction mixture; and(b) passing the resulting liquid reaction product, into a second reaction stage, at a temperature of 80.degree.-140.degree. C. over a fixed-bed catalyst;wherein a catalyst having an exchange capacity of 70-120 m. equivalents/100 cm.sup.3 is used in both reaction stages.

    Abstract: An improved process for the continuous alkylation of phenol with olefins having 6 to 12 carbon atoms in the liquid phase and in the presence of strongly acid ion exchange resin catalysts mounted in a fixed bed. The phenol and olefins are passed in a first stage at temperatures from about 80.degree. to 120.degree. C. over an ion exchange resin catalyst having an exchange capacity of from 50 to 96 m Val per 100 ml of catalyst and then passed in a second stage at temperatures about 110.degree. to 130.degree. C. over another ion exchange resin catalyst having an exchange capacity of from 100 to 180 m Val per 100 ml of catalyst.
