  • Patent number: 5043501
    Abstract: A process for producing 2,6-dimethylnaphthalene by alkylation of an alkylaromatic, e.g. toluene, with a C.sub.5 olefin alkylating agent, e.g. 1-pentene, in the presence of a suitable alkylation catalyst, and dehydrocyclization of the resulting alkylate with a dehydrocyclization catalyst to generate a dimethylnaphthalene product rich in the 2,6-isomer. Additional process steps can include isomerization of the product and further alkylation.

  • Patent number: 4980333
    Abstract: Perovskite related materials of high thermal stability and surface area which contain interspathic polymeric chalcogenides such as polymeric silica are prepared by ion exchanging a layered metal oxide, such as layered titanium oxide, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming a polymeric oxide, is thereafter introduced between the layers. The resulting product is treated to form polymeric oxide, e.g. by hydrolysis, to produce the layered oxide material. The resulting product may be employed as catalyst material in the conversion of organic compounds.

  • Patent number: 4967030
    Abstract: It has been discovered that low viscosity lubricant can be prepared in high yield by catalytically cracking higher molecular weight oligomers of C.sub.6 -C.sub.20 alpha-olefins prepared by oligomerization in contact with reduced chromium oxide catalyst on solid support. Further, it has been discovered that the reduced viscosity oligomers produced by cracking of high vicosity lubricant retains the superior characteristics of higher viscosity index and low pour point of the liquid lubricant starting material. The lubricants are cracked in contact with hydrogen and hydrocracking catalyst such as platinum or palladium on mildly acidic support. The support can be Al.sub.2 O.sub.3, acidified Al.sub.2 O.sub.3, SiO.sub.2, SiO.sub.2 /Al.sub.2 O.sub.3, zeolites comprising high silica ZSM-5, Beta, HY, USY, and clay. The reduced viscosity material is hydrotreated during cracking.
