Patent number: 5985804Abstract: It is disclosed that succinic acid and its derivatives that contain a branched aliphatic group on the 2 or alpha position of succinic acid form surfactants that exhibit a high order of or bioresistance to bacteriological degradation. Further, it has been discovered that these novel surfactants can be employed to prepare novel oil-in-water emulsions with lube oils such as mineral oil that are effective as cutting fluids for machining operations but provide an improved resistance to biodegradation to the cutting oil so formulated, without resorting to the inclusion of conventional biocides in the formulation. It has also been discovered that the bioresistance of the cutting fluid emulsion formulation can be further enhanced by using a branched aliphatic hydrocarbon oligomer or polymer as the lubricative component in the formulation. Cutting fluid emulsions so formulated are effective fluids in prolonging tool life and facilitating machining operations.Type: GrantFiled: March 18, 1992Date of Patent: November 16, 1999Assignee: Mobil Oil CorporationInventors: Henry Ashjian, Thomas J.

Patent number: 5417869Abstract: The invention relates to bioresistant surfactants and cutting fluid compositions which utilize them. The surfactants consist of soaps of carboxylic acid compounds having from 10 to 30 carbon atoms, the carbon skeleton of which is branched and not straight chain. It is the branching which lends the resistance to biodegradation to the products of the invention. Further enhanced bioresistance may be obtained by utilizing a branched lubricating basestock material in the cutting fluid composition.Type: GrantFiled: January 10, 1994Date of Patent: May 23, 1995Assignee: Mobil Oil CorporationInventors: Thomas J. Giacobbe, Frederick C. Loveless, Carl R. Mackerer, Norman J. Novick, Douglas G. Placek

Patent number: 5245072Abstract: This invention relates to processes for making biodegradable surfactant. The process comprises several steps including an optional step. The first step is directed to reacting olefins with ZSM-23 catalyst to form oligomers having the formula -(C.sub.3).sub.x, (C.sub.4).sub.x or mixtures thereof. Second, the oligomer is hydroformylated to form a saturated alcohol, for example, tridecanol. Next, the saturated alcohol is ethoxylated. Thereafter a nonionic biodegradable surfactant is recovered. This surfactant can be used in detergent formulations. A process is also taught for making esters which can be used as lubricants or plasticizers. A specific hydroformylation process is taught which utilizes modified cobalt carbonyl catalyst. Also, a specific ethoxylation process is taught. Products formed according to the latter two processes as well as their uses are also taught.Type: GrantFiled: February 24, 1992Date of Patent: September 14, 1993Assignee: Mobil Oil CorporationInventors: Thomas J. Giacobbe, George A. Ksenic

Patent number: 4675369Abstract: A catalyst composition for polymerizing alpha-olefins in a gas phase continuous process is prepared by combining a catalyst precursor with a catalyst activator in such proportions that the polymer product comprises about 9.times.10.sup.-7 to about 18.times.10.sup.-7 gram-moles of the activator per gram of the polymer produced. The use of the activator in these proportions lowers the partial pressure of the monomers used in the process without sacrificing quality of the product. The catalyst precursor is prepared by reacting a carrier having OH groups with a stoichiometric excess, with respect to the OH groups, of an organomagnesium composition, and subsequently reacting the product with a transition metal compound.Type: GrantFiled: October 4, 1985Date of Patent: June 23, 1987Assignee: Mobil Oil CorporationInventors: John E. Cook, Thomas J. Giacobbe, Robert O. Hagerty

Patent number: 4629903Abstract: A method for monitoring the feed of a catalyst, especially the feed of a catalyst employed in a gas-phase linear low density polyethylene process system through the intermediary of the electro-optical scanning of an intermittent flow of the catalyst. The invention also relates to an apparatus for monitoring the catalyst feed in a gas-phase linear low density polyethylene process for the implementing of the inventive monitoring method. An intermittent flow of the catalyst, which is generally opaque, is monitored through the utilization of fiber optics and a light source and light detector device, wherein light which is conducted through the fiber optics passes through a clear or transparent flow channel through which there is effected the catalyst flow, and is monitored through a suitable photocell. The catalyst particles will interrupt the light beam while traversing the transparent flow channel and allow this to be registered by the photocell on a suitable indicating instrument.Type: GrantFiled: October 9, 1984Date of Patent: December 16, 1986Assignee: Mobil Oil CorporationInventors: Thomas J. Giacobbe, Richard H. Leitman, Walter Terebecky
