Abstract:
An alkaline earth metal sulfonate of high alkalinity is prepared by reacting an alkaline earth metal base, e.g. calcium hydroxide, with carbon dioxide in the presence of the metal sulfonate and an alkaline earth metal phenate, there also being present a polar solvent such as benzyl alcohol or tetrahydrofurfuryl alcohol, as well as free phenol in an amount over and above the stoichiometric quantity necessary to form metal phenate by reaction with the metal base. At the end of the reaction the solvent and free phenol are removed from the product by distillation. Preformed metal phenate can be used at the beginning of the reaction or the metal phenate can be formed in situ, starting with free phenol. Also, in place of metal sulfonate, free sulfonic acid can be used initially, with sufficient metal base to convert it to metal sulfonate. The attainment of total base numbers of 400 or more is possible by use of a second dispersant along with the metal sulfonate. This second dispersant, which is used with the sulfonate in the proportion of 0.1 to 1 part per part of sulfonate, can be a thioacid of phosphorus, or metal salt thereof, obtained by reaction of a sulfide of phosphorus on a hydrocarbon; an alkyl phenol or alkyl phenol sulfide, or metal salt thereof; or a monocarboxylic or polycarboxylic acid or anhydride, or metal salt thereof, characterized by a long chain hydrocarbon group of from about 20 to 200 carbon atoms, as for example, a polyisobutenyl succinic acid.
Abstract:
1. The production of a gel which comprises incorporating into a normally liquid hydrocarbon a small proportion effective to form a gel of at least one liquid hydrocarbon dispersible copolymer selected from the group consisting of rubbery and solid copolymers compound represented by the formula WHEREIN R is selected from the group consisting of hydrogen, alkyl and alkoxy; and R'' is selected from the group consisting of WHEREIN X is selected from the group consisting of hydrogen, alkyl and a halogen, Y is selected from the group consisting of hydrogen, alkyl and aryl; wherein R'''' is selected from the group consisting of alkyl, cycloalkyl, aryl, alkaryl, and aralkyl; the total of the carbon atoms in R and R'' when R'' does not contain R'''' is two to eight; and wherein when R'''' is present the total of the carbon atoms in R and R'' is two to thirteen and a copolymerizable compound containing a basic tertiary amine group selected from the group consisting of vinylpyridines, vinylquinolines and their nuclear-alkyl-substituted derivatives containing not more than a total of 12 carbon atoms in the nuclear-substituted groups, said copolymerizable compound containing not more than a total of 12 carbon atoms in the hydrocarbon groups attached to the nitrogen atom, said copolymer having been prepared using 0.25-8 parts per 100 by weight of total monomeric material.
Abstract:
Compositions useful as antioxidants, corrosion inhibitors and extreme pressure agents in lubricants are prepared from hydrazine or a substituted hydrazine, carbon disulfide, and the product obtained by reacting a hydroxy-substituted phosphorothioic acid triester with an inorganic phosphorus acid, oxide or halide and neutralizing a substantial portion of the acidic intermediate thus obtained with an amine.
Abstract:
METHOD FOR APPLYING A COATING TO A METALLIC SURFACE, THE SURFACE BEING IMMERSED IN AN ACIDIC AQUEOUS COATING COMPOSITION COMPRISING AN ORGANIC COATING-FORMING MATERIAL, AN OXIDIZING AGENT, HYDROGEN ION AND AN ANION, WHEREIN THE WEIGHT OF THE COATING FORMED ON THE SURFACE CAN BE CONTROLLED BY THE TIME THE SURFACE IS IMMERSED IN THE COMPOSITION.
