Abstract:
A process for separating a hydrophobic hydrocarbon chemical from an aqueous emulsion and recycling the majority of the water, co-solvents, salts, and the emulsifier is set forth. A preferred emulsifier is a salt of a carboxylic acid, phosphoric acid or sulfonic acid having an amine in the hydrophobic portion of the emulsifier, said amine being capable of being protonated to change (increase) the water solubility of the entire emulsifier molecule. The process is useful for soil remediation by extraction in that it facilitates the recycling of the water and emulsifier dramatically reducing the amount of water and emulsifier used in remediating a site. A method for remediating contaminated soil using the process is also set forth.

Abstract:
Hydrocarbyl substituted carboxylic compositions and derivatives thereof useful as additives for lubricating oil and fuel compositions. Carboxylic compositions are derived from (A) an olefinically unsaturated hydrocarbon, said hydrocarbon having at least one allylic hydrogen atom, and (B) an alpha , beta -unsaturated carboxylic compound prepared by reacting (1) an active methylene compound of formula (I) and (2) a carbonyl compound of general formula (II) wherein R is H or hydrocarbyl and R is a member of the group consisting of H, hydrocarbyl and (III), wherein each R' is independently R or OR and each R is, independently, H or a hydrocarbyl group; and lower alkyl acetals, ketals, hemiacetals and hemiketals of the carbonyl compound (2). Carboxylic derivative compositions are obtained by reacting the carboxylic compositions with a reactant selected from the group consisting of (a) amines characterized by the presence within their structure of at least one condensable H-N

Hydrocarbyl substituted carboxylic compositions and derivatives thereof useful as dispersant/viscosity improvers for lubricating oil and fuel compositions. Carboxylic compositions are derived from (A) a hydrocarbon polymer having Mn ranging from about 20,000 to about 500,000, and (B) an alpha , beta -unsaturated carboxylic compound prepared by reacting (1) an active methylene compound of the formula (I), and (2) a carbonyl compound of the general formula (II), wherein R is H or hydrocarbyl and R is a member of the group consisting of H, hydrocarbyl and (III), wherein each R' is independently R or OR and each R is, independently, H or a hydrocarbyl group; and lower alkyl acetals, ketals, hemiacetals and hemiketals of the carbonyl compound (2). Carboxylic derivative compositions are obtained by reacting the carboxylic compositions with a reactant selected from the group consisting of (a) amines characterized by the presence within their structure of at least one condensable H-N
Abstract:
PROBLEM TO BE SOLVED: To obtain a low-chlorine-content composition by reacting a halogenated polyolefin obtained by reacting a polyolefin terminated with a tetra-substituted or tri-substituted unsaturated group with a halogen with an α,β-unsaturated acid, its anhydride or its derivative to obtain a polyolefin-substituted reaction product. SOLUTION: A tetra-substituted or tri-substituted unsaturated terminal- containing polyolefin such as polyisobutylene having a number-average molecular weight of 300-5,000 is mixed with a halogen such as chlorine, and the mixture is reacted under heating to form a partially halogenated polyolefin. Next, 0.1-10mol, per mol of the polyolefin, of an α,β-unsaturated acid such as maleic anhydride is added to the reaction mixture and reacted to obtain a polyolefin- substituted reaction product. This product has a halogen content of below 1,000ppm and is reacted with an amine, an alcohol, a reactive metal or a reactive metal compound to form a dispersing agent.
Abstract:
PROBLEM TO BE SOLVED: To enable the conversion of a low reactive alkylating agent into the one having high reactivity by passing the low reactive alkylating agent through the vapor phase on a catalyst. SOLUTION: (A) A low reactive alkene is passed through the vapor phase on (B) a catalyst (preferably a sulfuric acid-activated clay, an iron oxide, etc., on alumina) to produce (C) a highly reactive alkene. The component A is capable of producing
