The present invention relates to zeolitic adsorbents based on agglomerated crystals of FAU zeolite containing barium and/or potassium, with large external surface area, combining optimum properties in terms of selectivity and mechanical strength. These adsorbents find applications in the separation of cuts of C8-aromatic isomers and notably of xylenes, in the separation of isomers of substituted toluene such as nitrotoluene, diethyltoluene, toluenediamine, in the separation of cresols, and in the separation of polyhydric alcohols such as sugars.

The present invention relates to a method of preparing ortho substituted phenols from 2,5-dimethylfuran and propargyl ethers in the presence of a gold(I) complex. It is particularly advantageous to use 2,5-dimethylfuran as this offers an ecological beneficial synthesis of said ortho substituted phenols.

The present disclosure is directed to a nitrocellulose-based propellant composition comprising: (a) a nitrate ester-based propellant comprising nitrocellulose; and (b) a stabiliser comprising a non-aromatic compound (12) consisting of a general ionone formula (12-I), (12-II), (12-III) or (12-IV): ##STR00001##
wherein R.sup.1 represents a ketone, hydroxyl, carboxyl, aldehyde or an unsaturated alkyl group, preferably C(O)CH.sub.3 (corresponding to alpha, beta, gamma and pseudo ionone).

Processes and apparatus for making xylenes and phenol are described. Phenol and alkyl phenols are separated from coal derived liquid. The phenol is separated from the alkyl phenols. The alkyl phenols can be reacted with aromatics such as benzene and toluene to make xylenes. The xylenes and other aromatics are then separated from the phenol and alkyl phenols. Para-xylene is separated and recovered using a xylene separation process, and meta-xylene and ortho-xylene are optionally converted to para-xylene through an isomerization reaction.
