    摘要: The present invention relates to the use of secondary alkanesulphonic acids as asphaltene dispersing agent in crude oils and products derived therefrom, wherein a chain length of 8 to 22 C atoms is present. The secondary alkanesulfonic acids are employed in an amount of from 1 to 10,000 ppm by volume. The alkanesulfonic acid is preferably formulated as a solution or microemulsion, and can further contain optional alkyl-formaldehyde resin, oxyalkylated amines, or wax-dispersing agents. The alkanesulfonic acids provide reduced precipitate amounts, slow the rate of precipitate formation, form a more finely divided precipitate and reduce the tendency of the precipitate to be deposited on surfaces.

    摘要: A scratch-off lottery game card that simulates the rules of the game of Bingo. On the card, there is a first set of game indicia of a first type arranged in a grid that has at least one row of cells having a indicia of a second type with a unique one of the indicia of the second type defining a particular column of the grid. There is a second set of game indicia on the card, each a grouping of one of the first and second type of game indicia such that each defines a potential one of the first type of indicia in a column of cells of the grid of first set of game indicia. A set of prize indicators is adjacent the grid of the first set of game indicia thereby defining a row of the grid and indicating the prize for matching a defined row.

    摘要: A process for producing organic acid esters using continuous countercurrent reactive distillation using acid catalysts in a structured packing in a single column (10) is described. In the reactive distillation an organic acid ester is formed by chemical reaction and can be purified to its final state within the single column. Organic acid esters are produced at relatively low cost, with less waste production, and in a less complicated manner than prior processes. Organic acid ester have uses as solvents, as intermediate chemicals, and in consumer products.
