摘要： The present invention is a process for producing phenyl-alkanes at alkylation conditions in the presence of a zeolite having an NES zeolite structure type, such as NU-87. This invention produces phenyl-alkanes having lightly branched aliphatic alkyl groups which are used to produce modified alkylbenzene sulfonates that have improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates.

摘要： A process for separating the isomers of dichlorobenzene from a feed mixture of the same. Separation of the isomers is effected by selective absorption and desorption and is susceptible to various flow schemes for performing continuous adsorptive separations. The process uses an X-type zeolite adsorbent having a mixture of sodium and potassium ions in the exchangeable cationic sites. The desorbent may be an alkyl benzene, such as toluene, xylene, p-diethylbenzene, etc.
