TL;DR: In this paper, the results from the Black Mesa Pipeline slurry were compared with results from Wyodak, Illinois No. 6 and Black Mesa pipeline slurry using a capillary column GC/MS of the methyl ethers.
Abstract: Organic compounds in the water separated from coal pipeline slurry has been investigated on a laboratory basis for the slurry with each of three subbituminous coals: Wyodak, Illinois No. 6 and Black Mesa. The results are compare with results from the Black Mesa Pipeline slurry. Compounds such as aryl hydrocarbons, nitrogenous bases, aryl thiophenes and aryl ethers are all more than 99.9% adsorbed when added to water before slurry formation and are undetectable in the resulting slurry waters. Phenols occur in slurry waters and their identification and quantification using methylation with perdeutero phenol as an internal standard for capillary column GC/MS of the methyl ethers is described. Phenol, o-cresol, p-cresol, 2,6-dimethyl phenol, o-ethyl phenol and 3,5-dimethyl phenol were identified and quantified in all slurry waters from each coal. Laboratory results on slurry waters from Black Mesa coal are in agreement with the results for these phenols in the clariflocculator overflow water at the Mohave Generating Station. 4 figures, 13 tables.

TL;DR: In this paper, a method for producing o-cresol and 2,6-xylenol using the catalyst is provided to stably produce o cresol to a high yield even without frequently performing a reactivating operation of the catalyst.
Abstract: A catalyst for alkylation of phenol and a method for producing o-cresol and 2,6-xylenol using the catalyst are provided to stably produce o-cresol and 2,6-xylenol to a high yield even without frequently performing a reactivating operation of the catalyst. A catalyst for alkylation of phenol is represented by the chemical formula 1, Fe1.0VaM1bM2cSidOx, where M1 denotes one or more components selected from the group consisting of cobalt(Co) and nickel(Ni), M2 denotes one or more components selected from the group consisting of manganese(Mn), molybdenum(Mo), zinc(Zn), and magnesium(Mg), catalyst components of Fe, V, M1, M2, and Si are present in the oxide state, a, b, c, and d denote mole ratios of the components V, M1, M2, and Si based on 1 mole of Fe, a ranges from 0.5 to 2, b rages from 0.01 to 0.5, c rages from 0 to 0.5, d rages from 0.01 to 1.0, and x is determined according to values of the a, b, c and d, and oxide states of the components Fe, V, M1 and M2 based on 1 mole of Fe.

TL;DR: In this article, various compositions of zinc manganese ferrospinels and their lanthana modifications were tested as catalysts for the vapor phase alkylation of phenol with methanol.
Abstract: Various compositions of zinc manganese ferrospinels and their lanthana modifications were tested as catalysts for the vapor phase alkylation of phenol with methanol. The zinc manganese ferrospinels were prepared by the controlled low temperature hydroxide co-precipitation method and their lanthana modification by the wet impregnation method. The prepared systems were characterized by various physico-chemical methods. All the ferrite samples proved to be active for the alkylation of phenol using methanol and lanthana modified systems exhibited cent percent for o-cresol. Being an acid–base catalyzed reaction, the enhancement in the phenol conversion for the phenol alkylation reaction using methanol in the prepared systems is mainly due to their increased acidity, especially in the strong regions. Under the optimized reaction conditions, all the systems showed constant activity for a long time.

TL;DR: In this paper, the solubilities and equilibria at 20° in the system phenol, o-cresol, water, sodium hydroxide have been determined, showing that the separation factor of the phenols between aqueous and phenolic phases is not sensitive to the alkali content of the solution.
Abstract: Solubilities and equilibria at 20° in the system phenol, o-cresol, water, sodium hydroxide have been determined: solubilities up to rather more than 3% of sodium hydroxide (complete miscibility), and equilibria to a lower value. The measurements indicate that the separation factor of the phenols between aqueous and phenolic phases is not sensitive to the alkali content of the solution.
