508591, 44459, 585 10, 5253317, 5253319, 5253337

Abstract:

Polymers (including copolymers) derived from one or more olefins, such including ethylene and C -C -olefins such as propylene and 1-butene, which polymers have (a) an average ethylene sequence length, ESL, of from, about 1. 0 to less than about 3. 0; (b) an average of at least 5 branches per 100 carbon atoms of the polymer chains comprising the polymer; (c) at least about 50% of said branches being methyl and/or ethyl branches; (d) at least about 30% of said polymer chains terminated with a vinyl or vinylene group; (e) a number average molecular weight, Mn, of from about 300 to about 15,000 when the polymer is intended for dispersant or wax crystal modifier uses and up to about 500,000 where intended for viscosity modifier uses; and (f) substantial solubility in hydrocarbon and/or synthetic base oil. The polymers are produced using late-transition-metal catalyst systems and, preferably, inexpensive, highly dilute refinery or steam cracker feed streams that have undergone only limited clean-up steps. Fuel and lubricating oil additives, particularly dispersants, wax crystal modifiers and flow improvers, are produced.

International Classification:

E21B 2800

US Classification:

166299, 166300, 1663082

Abstract:

A method for recovering oil in a reservoir by generating chemical microexplosions in the reservoir. The invention treats the hydrocarbon-bearing reservoir by decomposing in situ at least one PEH-3CO, thereby generating heat, shock, and CO. A preferred method comprises the steps of depositing PEH-3CO into the formation and depositing an acid into the formation to cause the PEH-3CO to decompose and generate heat and gas.

International Classification:

C07C 45/00
C07C 37/08

US Classification:

568385, 568798

Abstract:

A process for producing phenol and methyl ethyl ketone comprises contacting benzene with a Calkylating agent under alkylation conditions with catalyst comprising zeolite beta or a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12. 40. 25, 6. 90. 15, 3. 570. 07 and 3. 420. 07 Angstrom to produce an alkylation effluent comprising sec-butylbenzene. The sec-butylbenzene is then oxidized to produce a hydroperoxide and the hydroperoxide is decomposed to produce phenol and methyl ethyl ketone.
