Abstract: Polycyclic aromatic compounds, such as biphenyl, are alkylated with an alkylating agent, such as propylene, in the presence of an acidic mordenite zeolite catalyst under conditions sufficient to produce a mixture of substituted polycyclic aromatic compounds enriched in the para alkylated isomers, such as p,p'-di(isopropyl)biphenyl. The novel acidic mordenite catalyst is characterized by its silica/alumina molar ratio, its porosity, and a Symmetry Index. The p,p'-disubstituted isomers of polycyclic aromatic compounds are useful as monomers in the preparation of thermotropic, liquid crystal polymers.

Abstract: There is provided an improved process for producing biologically active arylterpenoid compounds useful to inhibit eclosion of pupae, e.g., fly pupae or mosquito pupae. The process is characterized by reacting a terpenoid material having a terminal unsaturated linkage, e.g., dihydromyrcene (3,7-dimethylocta-1,6-diene) with a lower alkyl Grignard reagent, e.g., n-propyl magnesium chloride to form a Grignard exchange product. The exchange product is then benzylated. Either a benzyl halide, e.g., p-isopropylbenzyl chloride, or a benzaldehyde, e.g., p-isopropylbenzaldehyde may be used. These compounds are specifically described in U.S. Pat. No. 4,002,769. They contain also a lower alkoxy group, e.g., methoxy. This can be introduced prior to the formation of the Grignard exchange product or at a later stage in the operation. Use of the exchange-type Grignard reaction enables elimination of several steps when producing the arylterpenoids from pinene as the terpene source, and consequent costs.

Abstract: Properties of phenol-containing hydrocarbonaceous streams are improved by first treating the stream with a C.sub.1 to C.sub.10 alcohol and an acid. If enough alcohol and acid are employed, two liquid phases are formed, an alcohol/acid phase and a hydrocarbonaceous phase. The alcohol/acid phase, which now contains phenols, can be separated and contacted with a C.sub.1 to C.sub.16 olefin or the olefin can be added in situ. In any case, oxygen-alkylation of the phenolic groups occurs.
