20140059827 | METHOD FOR CUTTING TO LENGTH A PIECE OF TUBE FROM A TUBE - A method for cutting to length a piece of tube having an inner tube and an outer tube sheathing, the piece of tube being detached with the aid of a cutting tool at a cutting site in a plane oriented transversely to the longitudinal extent of the tube. The tube sheathing is surrounded by a severable tube fixing element, which covers over the intended cutting site before the piece of tube is detached using the cutting tool at the cutting site, and the tube fixing element completely encloses the outer tube sheathing in the circumferential direction. The tube fixing element is fixed on the tube sheathing and/or the tube enclosed by the tube fixing element is severed with the cutting tool such that a relative displacement of the tube fixing element with respect to the tube sheathing or of the tube sheathing with respect to the inner tube is prevented. | 03-06-2014 |

20100113836 | METHOD FOR PRODUCING HYDROXY PIVALIN ALDEHYDE AND NEOPENTYL GLYCOL - The preparation of hydroxypivalaldehyde is effected by aldolizing isobutyraldehyde with formaldehyde and subsequently working up the resulting reaction effluent by distillation, wherein the reaction effluent is fed to a distillation column which is operated at a top pressure in the range from 0.5 to 1.5 bar and in which a two-stage condensation is provided in the top region, in which the vapors are first conducted into a partial condenser operated at a temperature in the range from 50 to 80° C., whose condensate is recycled at least partly into the distillation column, and in which the vapors uncondensed in the partial condenser are fed to a downstream condenser operated at a temperature in the range from −40 to +30° C., whose condensate is at least partly discharged. | 05-06-2010 |
20110272270 | Process for Preparing Polymethylols - The present invention relates to a process for recovering components from a low boiler mixture which is obtained in the distillation of hydrogenation effluents from the preparation of polymethylols, by multistage distillation of the low boiler mixture comprising a tertiary amine, water, methanol, polymethylol of the formula (I) | 11-10-2011 |
20120004472 | METHOD FOR PREPARING POLYMETHYLOLS - The present invention relates to a process for distilling an aqueous polymethylol mixture which comprises a polymethylol of the formula (I) | 01-05-2012 |
