    摘要： The present invention provides an integrated process for continuously preparing 1,4-butanediol, which comprises the following stages: (I) reacting formaldehyde with acetylene in the presence of a copper catalyst at a pH of from 5 to 8 and a molar ratio of formaldehyde to acetylene of at most 2:1, (II) intermediately buffering the resulting butynediol-containing aqueous mixture for from 0.1 to 100 h, (III) hydrogenating the mixture obtained after the intermediate buffering and (IV) distilling the hydrogenation product obtained in stage III to obtain 1,4-butanediol.

    摘要： Novel crystalline forms of and a process for converting perylene-3,4:9,10-tetracarboximide of the general formula I to a form used as a fluorescent dye. The process including: a) dissolving or suspending the perylene-3,4:9,10-tetracarboximide in a solvent to obtain a solution or suspension; and b1) cooling the solution obtained in step a) to a temperature at or below the crystallization temperature of the perylene-3,4:9,10-tetracarboximide and, if the solvent is organic, removing excess solvent until the first crystals form, otherwise, adding water or dilute aqueous solutions of the solvent until the first crystals form, and maintaining the solution at that temperature for further crystallization; or b2) cooling the suspension obtained in step a) to or below the crystallization temperature when the temperature in step a) was above the crystallization temperature, and maintaining the suspension at the temperature for further crystallization to form one or more solvate crystals.
