Patent number: 12116540Abstract: Polymeric mist control materials, methods of forming polymeric mist control materials, and methods of using such materials for mist control are provided. The polymeric mist control additives are formed of molecules comprised predominantly of monomers that confer high solubility in fuel and include associative groups that attract each other in donor-acceptor manner, and are incorporated such that multiple associative groups are in close proximity (“clusters”), such that the clusters are separated by very long non-associative sequences.Type: GrantFiled: March 7, 2022Date of Patent: October 15, 2024Assignee: California Institute of TechnologyInventors: Ming-Hsin Wei, Julia A. Kornfield, Ralph Leonard Ameri David

Patent number: 5935276Abstract: A method of impeding the evaporation of a solvent by at least partially dissolving a solvent soluble polymer in the solvent in sufficient amounts so as to impede the evaporation of the solvent is disclosed. In one embodiment the soluble polymer may be selected from the group including oligomeric or polymeric homo-, co-, and terpolymers wherein a vinylcyclohexyl moiety comprises at least 10% weight of the polymer. Another aspect is generally directed to a method of storing a solvent including placing the solvent in a suitable container for storage, and dissolving in at least a portion of the solvent sufficient amounts of a soluble polymer so as to impede the evaporation of the solvent. Also described are compositions including a solvent and a polymer dissolved in the solvent so as to impede evaporation of the solvent.Type: GrantFiled: July 29, 1997Date of Patent: August 10, 1999Assignee: Texaco IncInventors: Thomas F. DeRosa, Joseph M. Russo, Benjamin J. Kaufman, James R. Ketcham

Patent number: 5837867Abstract: The present invention is directed to the use of cyclic amide alkoxylate compounds as additives in fuel compositions having a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of one or more cyclic amide alkoxylate compounds of the formula: ##STR1## wherein x is from 2 to 20 and y is from 1 to 50. R.sub.1 and R.sub.2 are independently hydrogen or hydrocarbyl of 1 to 100 carbon atoms. R.sub.3 is hydrocarbyl of 1 to 100 carbon atoms and R.sub.4 is independently hydrocarbyl of 2 to 100 carbon atoms. R.sub.5 is hydrogen, hydrocarbyl of 1 to 100 carbon atoms or acyl of 1 to 20 carbon atoms.The invention is also directed to the use of these cyclic amide alkoxylate compounds for decreasing intake valve deposits, controlling octane requirement increases and reducing octane requirement. The invention is further directed to novel cyclic amide alkoxylate compounds.Type: GrantFiled: August 6, 1996Date of Patent: November 17, 1998Assignee: Shell Oil CompanyInventors: Jiang-Jen Lin, Charles Lee Edwards, Pen-Chung Wang, Garo Garbis Vaporciyan
