Abstract:
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.
Abstract:
Gums and inorganic corrosion byproducts occurring in distilled petroleum fractions may be dispersed and resulting fouling controlled by adding to the petroleum distillate an effective dispersing amount of a monosubtituted alkylphenol polyethylenepolyamine-formaldehyde resin, such resins having a weight average molecular weight of from about 1,000 to about 10,000, and an alkyl substituent containing from about 4 to about 24 carbon atoms, which alkyl substituent may be a linear or branched.
Abstract:
This invention concerns a an amidoalkanolaminoester composition obtained by reacting: (1) a reaction product of dialkyl maleate such as diethyl maleate and an alkylalkanolamine such as N-methylethanolamine; with (2) a hydrocarbyl oxypolyoxyalkene amine represented by the formula ##STR1## in which R represents an alkyl, an alicyclic, an alkylalicyclic radical having from 12 to 30 carbon atoms, or R'--Ar--; wherein R' represents a hydrocarbyl radical having from 4 to 12 carbon atoms; wherein x has a value of from about 10 to 16; wherein Ar is a divalent aromatic moiety such as divalent benzene; and wherein R" is an ethyl or methyl radical or a mixture of methyl and ethyl radicals. The amidoalkanolaminoester may be used as a fuel additive.
Abstract:
A low-sediment, low-tar, chlorine-free thermal process for preparing oil-soluble polyalkenyl derivatives of monounsaturated C.sub.4 -C.sub.10 dicarboxylic acid producing compounds is disclosed. The process involves reacting the dicarboxylic acid producing compound with a polyalkene at high temperature and under high inert gas partial pressure in the presence of a sediment-inhibiting amount of hydrocarbyl substituted sulfonic acid. The polyalkenyl derivatives are useful per se as additives in lubricating oils, functional fluids, and fuels and are also useful as intermediates in the preparation of other products (e.g., succinimides) useful as additives in lubricating oils, functional fluids, and fuels.
Abstract:
The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene/alpha-olefin/diene interpolymer of 300 to 20,000 number average molecular weight substituted with mono- or dicarboxylic acid producing moieties (preferably dicarboxylic acid or anhydride moieties), wherein the terminal unsaturation comprises terminal ethenylidene unsaturation. The mono- and dicarboxylic acid or anhydride substituted interpolymers of this invention are useful per se as additives to lubricating oils, and can also be reacted with a nucleophilic reagent, such s amines, alcohols, amino alcohols and reactive metal compounds, to form products which are also useful lubricating oil additives, e.g., as dispersants.
Abstract:
The pour point of paraffin-containing liquids is reduced by adding to the liquid an effective amount of a pour point depressant which is the reaction product of a hydrocarbyl-substituted phenol having a number average of greater than 30 carbon atoms in the hydrocarbyl-substituent, and an aldehyde of 1 to about 12 carbon atoms, or a source therefor. The pour point depressant is particularly useful for treating crude oils which have an initial pour point of 4.degree. C. or higher.
Abstract:
Compositions comprising hydroxyl group containing acylated nitrogen compounds, a process for reacting certain carboxylic reactants with olefinic compounds then reacting the product prepared thereby with ammonia, a hydrazine or an amine, products prepared thereby and lubricating oil and fuel compositions.
Abstract:
Reaction products of amino-alkylenecarboxylic acids with polyoxyalkylene compounds are used as paraffin dispersants for mineral oil middle distillates.
Abstract:
This invention relates to novel azo-dicarbonylo derivatives of a C3-C4 olefin polymers of the formula ##STR1## These can be prepared by reacting an ene compound such as a polypropylene or a polybutene, especially those with a vinylidene group, with an enophile such as X--CO--N.dbd.N--CO--Y. The resultant products can be used either as such or after further functionalization with eg polyamines as an additive for fuels and lubricants.
