    摘要： Provided herein are sulfosuccinamates made using polyetheramines as intermediates. The sulfosuccinamates according to the invention exhibit excellent detergency when employed in formulations used as hard surface cleaners, laundry detergents, and dishwashing liquids. In addition, the sulfosuccinamates according to the invention have an unexpectedly high degree of water hardness tolerance, and are easier to produce than similar materials found in the prior art owing to the fact that the product and its intermediates exist in liquid form.

    摘要： This invention is directed to detergent compositions which employ sulfonated alkyltoluenes as surfactants, wherein the sulfonated alkyltoluenes have a higher content of the sulfonated 2-phenyl alkyltoluenes isomers than was previously available in sulfonated alkyltoluene surfactants of the prior art. Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonated alkyltoluenes having lower contents of the 2-phenyl alkyltoluene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkyltoluenes are also provided, including dry cleaning formulations containing same. The alkyltoluenes of this invention may be combined with alkylbenzene surfactants in order to provide detergent blends having increased water hardness tolerance, lower Krafft temperature, and increased cleaning performance over what was previously afforded by the prior art.

    摘要： A process is described for preparing an activated porous phosphorus/vanadium oxide catalyst adapted for the catalytic oxidation of a hydrocarbon to produce a carboxylic acid anhydride. The catalyst comprises a shaped body having a volume of at least about 0.02 cc, a phosphorus content of between about 1.05 and about 1.20, a B.E.T. surface area of at least about 15 m 2 /g, an average vanadium oxidation state of between about 4.06 and about 4.3, a total pore volume of at least about 0.15 cc/g, a normalized apparent shaped body density of between about 1.0 and about 2.0 g/cc, and a crush strength of at least about 4 pounds [1.81kg]. At least about 20% of the pore volume of the catalyst is constituted of pores having a diameter between about 0.1 and about 3.3 µm, and at least about 40% of the pore volume is constituted of pores having a diameter of less than about 0.1 µm. The catalyst is prepared by mixing a particulate phosphorus/vanadium oxide precursor with a pore modification agent to produce a modified catalyst precursor composition, forming the modified precursor composition into a predetermined shape, and removing the pore modification agent substantially at a temperature below 300°C, preferably using air as a stripping gas.
