摘要:
Gamma-alkyl-gamma-butyrolactones having an alkyl substituent of at least 16 carbon atoms in length are reacted with amines or polyalkylenepolyamines, providing novel lactams useful as multifunctional agents in lubricants, fuels, coolants and other organic fluids.
摘要:
N-halo-5-(substituted-phenoxy or -pyridyloxy)-2-substituted benzoic acid sulfonamides and sulfamates, their preparation and use as herbicides are disclosed.
摘要:
Urea damage to the foliage of plants, particularly legumes such as soybeans, is reduced by application of corn syrup together with urea to the plant leaves.
摘要:
Metal salts and amides of alkyl-lactam acetic acids are prepared by reacting gamma-hydrocarbyl butyrolactone acetic acid compounds derived from alkenylsuccinic anhydrides with metal compounds and amines or amines alone. High molecular weight lactam acid salts and amides and metal complexes and metal carbamates thereof are useful as detergents or dispersants in organic industrial fluids. Another aspect of this invention is a method of preparing lactone acetic acids in yields up to 90% conversion from alkenylsuccinic anhydrides.

摘要:
Gamma-butyrolactones are formed by reacting an olefin with a compound containing a carboxylate moiety having at least one hydrogen atom on the alpha carbon atom in the presence of an ion of manganese, cerium, or vanadium, the ion being in a valency state higher than its lowest valency state.
摘要:
Succinimides of aminoaryl sulfonic acid salts provide exceptional detergency, viscosity control and anticorrosion properties to lubricants and greases and to other fluid compositions useful in hydraulic systems. Ammonium, alkylammonium, alkali metal, alkaline earth metal and groups IB, IIB, VIB, VIIB, VIII metal salts of aminoaryl sulfonic acid salts, and the salts of sulfanilic acid in particular, can be reacted with alkenyl or alkylsuccinic anhydride, acid or ester, in which the alkenyl or alkyl group may contain from 8 to about 500 carbon atoms, to yield the products of this invention. These products are understood to be novel. Suitable modifications of the aforementioned are the succinimides of di(aminoaryl sulfonic acid) salts, aniline disulfonic acid salts and corresponding aminonaphthalene sulfonate salts which are also useful in the compositions of this invention.
