Abstract: Separating sublimation products from gases in nested tube separators having heat exchange in the interior of the separator as well as from the outer wall, the outer wall being kept, during the sublimation and melting out of the sublimation product, substantially constantly at a temperature which is somewhat above the melting point of the sublimation product; in the corresponding apparatus, the heat exchange system for the interior and that for the exterior of the separator are separate from each other.

Abstract: A tubular reactor with forced circulation of a heat transfer medium which flushes the outside of the reaction tubes in axial direction, the heat transfer medium being supplied to, and withdrawn from, the reactor wall uniformly through circular pipelines, and particularly the constructional shape of deflecting guide plate means arranged transversely to the direction of flow and having annular openings around the reaction tubes for uniform flow towards all the tubes of the nest of tubes.

Abstract: Crystallite suspensions containing from 3 to 70 weight percent of a crystalline, ethylenically unsaturated polyester prepared through condensation polymerization, and having a molecular weight factor per double bond of 154.4 to 408, as the dispersed phase, and from 30 to 97 weight percent of a polyhydroxyl compound having a functionality of from 2 to about 8, a hydroxyl number of from 20 to 800, and a melting point of less than 30 DEG C. as the coherent phase are suitable for preparing non-cellular and cellular polyurethane- or polyurethane group-containing polyisocyanurate foams.
