Abstract:
Composition comprising an aqueous or partially aqueous functional fluid susceptible to degradation by a metal; and b) a metal deactivator having the formula I: ##STR1## in which X is a group having the formula II. ##STR2## in which R is hydrogen or C.sub.1 -C.sub.4 alkyl.
Abstract:
A process for stabilizing an ethylenically unsaturated monomer or oligomer from premature polymerization is disclosed whereby a stabilizing amount of an N-hydroxy substituted hindered amine is added to said polymerizable monomer or oligomer. The ethylenically unsaturated monomer or oligomer encompass vinyl monomers or oligomers bearing at least one polymerizable moiety. The N-hydroxy substituted hindered amine inhibits premature polymerization in the liquid and/or vapor phase.
Abstract:
Conductive fuel detergent compositions which posses not only the desirable characteristics of minimizing unwanted deposits on internal engine surface such as intake systems or port fuel injectors and exhibiting anticorrosion characteristics but also have conductive properties comprise quaternary succinimides which are characterized by having an oligomeric alkyl moiety on the succinimide ring. The additive may be prepared by condensing a (polyalkyl)succinic anhydride with a polyamino hydroxyalkyl quaternary ammonium salt, where the latter is formed by the reaction of a .OMEGA.-haloepoxide with a tertiary amine followed by reaction of the resulting product with a polyamine.
Abstract:
A distillate fuel, particularly one which has a high acid number initially or which develops a high acid number as a result of fuel degradation, stabilized with a diaminomethane of the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be independently a saturated or unsaturated hydrocarbon group, e.g., alkyl, aryl, aralkyl, alkaryl, cycloalkyl, alkenyl, aralkenyl, alkenylaryl, cycloalkenyl and the like or heterocyclyl groups and in which R.sub.1 and R.sub.2 and/or R.sub.3 and R.sub.4 may be joined together to form a five or six member heterocyclyl ring and R.sub.5 may be hydrogen or lower alkyl is disclosed. A method of stabilizing a fuel oil wherein a stabilizing amount of the above-mentioned diaminomethane is incorporated into the fuel oil is also disclosed.
Abstract:
Formulations of additives for engine fuels comprising at least one constituent (A) and one constituent (B) resulting from the reaction of at least one alkenyl or polyalkenyl-succinic derivative with at least one polyamine to form constituent (A) and with at least one 1-(2-hydroethyl) imidazoline substituted in the 2-position by a linear or branched alkyl or alkenyl radical with 1 to 25 atoms of carbon to form constituent (B). The preferred formulations also contain a constituent (C) consisting of at least one polyglycol soluble in said fuel, with an average molecular mass ranging from 480 to 2,100. The (A)/(B) and (A)+(B)/(C) molar ratios preferably are respectively 0.2/1 to 5/1 and 0.05/1 and 20/1.
Abstract:
Disclosed is an additive for liquid hydrocarbon fuel composition, particularly diesel fuels. The additive composition is the reaction product of polyalkenyl-substituted succinimides, aldehydes, and triazoles. It also finds use in lubricant compositions.

Abstract:
A method is disclosed for improving low temperature cold flow of fuel oils by using a cross-linked ester compound consisting essentially of a nitrogen-containing compound having hydroxyl group, a straight chain fatty acid, and a cross-linking agent.
Abstract:
A motor fuel composition which inhibits engine ORI and resists engine deposit formation comprises a mixture of hydrocarbons boiling in the range of 90.degree. F.-450.degree. F. and the reaction product of a dibasic acid anhydride, a polyoxyalkylene diamine, and a heterocyclic azole.
