Abstract:
An amidoalkanolamine composition having the formula:
wherein R is a monovalent aliphatic radical having 1 to 10 carbon atoms; R' is a hydrocarbyl radical having 8 to 30 carbon atoms; R'' represents methyl or a mixture of hydrogen and methyl radicals; and x is 5 to 50, can be added to fuel compositions to reduce deposits on the intake valve and combustion chamber of an i.c. engine. The amidoalkanolamine composition can be produced by reacting a 4-substituted-2-morpholinone having the formula:
with a hydrocarbyloxypolyoxyalkylene amine having the formula:
wherein R, R', R'' and x have the meanings given above.
Abstract:
The present invention provides a class of compounds, useful as gasoline detergent additives, comprising hydrocarbyloxypolyether allophonate esters of 2-hydroxy ethane. These allophonate esters can be represented by the formula:
where R is a C₉ - C₂₅ alkyl group, R¹ is a C₂ to C₄ oxyalkylene group, m is 0 or 1, and n is a number between 5 and 30.
Abstract:
Middle distillate fuel oil compositions such as diesel fuel or heating oil can be rendered storage-stable by an aromatic polyamine succinimide of a copolymer/maleic anhydride graft having the formula.
wherein (CP) is a copolymer and R is
where R and R are each aryl, alkylaryl, HN-Aryl, alkoxyl or H and n = 0 or 6.
Abstract:
An additive for a lubricating oil composition includes (a) a halogenated copolymer prepared from ethylene, a C₃ to C₁₈ alpha-olefin, preferably a C₃ to C₈, or mixtures thereof, and at least one halogen, and (b) an amino-aromatic polyamine compound.
Abstract:
An amido alkanolamine composition obtained by reacting
(a) a 4-alkyl-2-morpholinone represented by the formula: in which R represents an alkyl radical having from 1 to 10 carbon atoms, and (b) a hydrocarbylphenoxypolyoxyalkylene amine represented by the formula: in which R' represents a hydrocarbyl radical having from 4 to 30 carbon atoms, x has a value from 5 to 50, and R'' represents a methyl radical or a mixture of hydrogen and methyl radicals is provided.
Abstract:
Methyl tertiary butyl ether (MTBE) can be produced by reacting methanol with isobutylene, tertiary butyl alcohol (TBA), or preferably a mixture of isobutylene and TBA, in a distillation column packed with a sulfonic acid resin catalyst. The reaction proceeds substantially to completion and MTBE is distilled from the column with good purity.
