    摘要: The invention provides a means for greatly saving the thermal energy consumption in the dehydrating distillation of an aqueous solution of a carboxylic acid such as acetic acid by use of an azeotropically distilling entrainer boiling at a lower temperature than the carboxylic acid and immiscible with water. The improvement proposed by the invention comprises taking at least a part of the entrainer phase separated from the condensate coming from the column top or at least a part of the side-cut fluid abstracted from the refluxing fluid inside the column, evaporating the thus taken fluid into vapor and introducing the vapor into the distillation column at a stage for the introduction of the starting feed or below.

    摘要: Proposed is a novel and very efficient method for the preparation of an N-vinyl compound such as N-vinyl-2-pyrrolidone and N-vinyl-N-ethyl acetamide by the thermal decomposition of an N-(.alpha.-acyloxyethyl) compound which is a novel compound obtained by the addition reaction between an NH group-containing compound such as 2-pyrrolidone and N-ethyl acetamide and a vinyl carboxylate, e.g., vinyl acetate, in the presence of an alkali, e.g. alkali metal hydroxide. The reaction mixture after completion of this addition reaction as such, i.e. without isolating the N-(.alpha.-acyloxyethyl) compound, such as N-(.alpha.-acetoxyethyl)-2-pyrrolidone and N-(.alpha.-acetoxyethyl)-N-ethyl acetamide, is heated to effect in situ formation of the desired N-vinyl compound which can then be isolated by distillation under reduced pressure in a very high overall yield.

    摘要: A novel and effective catalyst system is provided for application in the preparation of alkenyl esters of carboxylic acids by transesterification reaction. The catalyst system consists of a palladium compound as the main ingredient and a cocatalyst formed of an alkali metal compound and a copper compound, at least one of which is a halide. The catalyst ingredients are adsorbed on a solid catalyst carrier, so that repeated use of the combined catalyst or a continuous operation of the reaction can easily be facilitated.

    摘要: A microscope apparatus has a sample table for supporting a sample and being mounted to undergo movement in a horizontal direction. A line sensor acquires a line image for each of a series of measuring positions of the sample in accordance with movement of the sample at a constant speed by one measuring width of the line sensor in the horizontal direction. An image processing device produces an image of the sample based on the line images acquired by the line sensor. A focusing device has a light-projecting member for projecting light onto the sample at a position forward of a leading side of an imaging range of the line sensor in the horizontal direction to prevent light reflected by the sample as a result of the projected light from being incident on and interfering with the line images acquired by the line sensor.
